Well, well, well, what do we have here? Might that be a long overdue update on the Neutrino Probe project? “No, that’s impossible!”, you might think. After all, the last update was almost exactly one year ago! How could this still be a go? Well, you better believe it ’cause this baby is alive and kickin’! Still not positive? Jump past the break to look for yourself. Have you ever been told that you’re hard to convince of something?

Sometimes, you want to finish something as quickly as possible. You desperately want to make progress, feel the urge to get back to it continuously and yet you can’t find any time to do just that. You just can’t, and every step takes forever as a result. That pretty much sums up the situation I’m in right now with this project.

Anyhow, as you can see I finally did manage to take the next step by finishing another important part of the tool – the business end! It’s a very detailed piece that consists of four separate parts right now (I’m not sure yet how I’m going to mold it though). And four very tiny parts I might add. The smallest one is only 5 mm in width!

This is by the way the part of the probe that was originally made from a disassembled nose hair trimmer. Unfortunately, despite my best efforts I wasn’t able to identify the exact model or even manufacturer of that trimmer, so I couldn’t use the original and had to scratch-build something instead. It was one hell of a lot of tedious work, but – to be honest – the result is probably nicer and cleaner than any found item, which makes the whole thing worthwhile in my book.

But, judge for yourself. To refresh your memory, here’s the front part of the original prop as well as the schematics I did as preparation for this project:

neutrino_probe_iaw_2

Schematics

And here are the pictures of my finished multi-part piece:

So, let’s get down to business. How did I create these parts? Here we go:

It all started with some more or less precisely cut pieces of styrene, my material of choice when it comes to scratch-building stuff.

They would make up the body of the largest piece. Which is round. Which meant that I had to sculpt it somehow since I didn’t have anything that I could’ve used as a base piece.

So I marked an appropriate line for the outer curvature on all pieces and cut them with an X-acto knife.

As you can see, I also cut some material away at the top to make it easier to create a recession there later.

Then I arranged them in a circular way to build a kind of skeleton structure and glued them together using plastic glue.

The next step was to fill the spaces between the “ribs” with putty to “put some meat on the bones” as it were. 😉

Then the sanding began. Oh, boy. The sanding – that’s the kind of work that I’d like to have an assistant do for me or something. On the other hand it gives you great control over the final shape of your piece. The downside is that it takes a long time. A very long time. And especially so if you’re only one bit as anal about a perfect surface as I am… 😉

While sanding the outer surface of this part I also paid some attention to the top side of it where I needed to have a pretty substantial indentation with a thin lip around it. To achieve this I used a mini-dremel with an appropriate attachment to remove material from both the surface inside as well as the “walls”.

Here is an intermediary result. Looks pretty nice already, doesn’t it?

On to the next part, which is essentially the same deal as the first one, except smaller and with a more straight profile. And when I say smaller I mean like 9,5 mm tall! That’s pretty tough to even hold in your hands (depending on what kind of hands you have of course). But holding it while trying to leave some room for sandpaper to work on it? Yep, you guessed it – that’s not easy to say the least. To illustrate: I even had to use tweezers to glue the “styrene skeleton” parts in place, which were only a couple of millimeters in width.

Here’s another preliminary result, this time a bit smoother. As you can see, I used spot putty on the smaller piece to fill in tiny holes and gaps.

And this is where Murphy came into play. It turned out that I had miscalculated something or simply had visually misjudged the proportions of this small piece. Anyway, it was evident that it was too thin and I had to somehow make it thicker – or wider if you look at it from the side.

Sounds easy, but how should I do that? Well, after thinking about it for a bit I decided to simply add material by gluing small strips of styrene to the side of it and fill it with putty as before. Yay, more sanding! Not exactly what I wanted to do but it sure did the trick:

After that small setback, I moved on to the next part, which is a kind of add-on to the first, “big” base piece. I made it basically from four small strips of styrene, which I glued together and sanded in shape.

A little putty to hide the seams:

A little sanding – done.

So, here are all of the three pieces that had been done at that point:

Next, I had to make the small, narrow part fit into the bigger base. So, I cut a piece out of the side of it and added some putty back in to make the new surface nice and smooth. Again, I used my mini-dremel to do that, this time with a small circular saw attached to it. I also used various small files to work on that slot.

While working on any of these pieces, by the way, I sprayed light coats of automotive primer on them all the time to reveal small blemishes, scratches or any kind of unevenness that needed to be fixed.

It wasn’t until I had created this slot that I noticed how deep I had carved the indentation into that big piece from above. Clearly too much! When put together, the final element of the prop would not have looked very good like that. So I had no choice but to improvise again and insert a round piece of styrene to raise the level of that surface a bit. This of course meant that I also had to putty it to blend it to the “walls” inside:

A lot of sanding later – and I mean a LOT of sanding later – the mistake was corrected and the surface both inside and outside was smooth as an androids butt. Also, the small add-on piece fit in its place perfectly.

To finish this piece off I had only one thing left to do and that was to create tiny grooves on the outside as a bit of detailing to give it some structure and make it interesting, not to mention match it with the original of course! To do that I cut tiny pieces of tape and put them on where I wanted the grooves to be.

Then I applied several coats of primer to add some material to the outside.

Then I removed the tape and voilà – micro-detailing! 🙂

Last but not least I had to tackle the emitter tip, which proved to be extra challenging. What I needed was a very small piece with very specific measurements and three tiny rings around it. At first I had no idea how to achieve this, but then decided to try to sculpt the tip from air curing clay which worked out quite well.

The three rings around the tip gave me a headache though. How the hell should I sculpt those by hand? It seemed impossible. Then I had the idea to wrap a bit of wire around it to at least get an approximation of what I wanted. It would be a short spiral instead of three separate rings, but that was the best I could think of. And it turned out that it worked really well and looks very nice even if it’s not perfect. After all, it’s only a very small part of the final prop…

So, here’s the final result again:

Note that I added a small indentation on top of the middle sized piece as well, similar to the one on the big base piece to create a small lip and a place for the emitter tip to fit in.

Seeing those four parts together now that they’re finished, I’m very satisfied with this part of the probe and I think it goes very well with the main parts I did a while back:

neutrino_probe_wip3_4666

I’m sure it’ll be a great prop when it’s all done. And I sure hope that I’ll be able to make some more progress in the near future, too! 🙂

tn_picards_briefcase

Ah, Starfleet cases. They come in all colors and shapes and I love all of them! Especially the ones that were used by the engineering staff to carry around their great little tools and instruments. But that’s not the only use for them, of course. They’re also very useful to store PADDs for example. And that’s exactly what Captain Picard uses his briefcase for in the TNG-Episode “Starship Mine” (6×18) when he leaves the ship, which is due for a Baryon sweep that requires a complete evacuation.

Prop-makers love to use everyday items, re-dress them a little and let them appear in a futuristic environment. It’s cheap, it looks convincing and it doesn’t take much time to do it. Because of that, most of the cases that appear on Star Trek are actual cases, that have a unusual twist or a unique look to them. It’s the same with Picards briefcase, which is actually a uncommonly shaped CD case from the eighties. The good thing about this is, that any “replica” made from the same type of case is 100% accurate in size and material, which is also the case with my prop.

The case itself does not give away too much about the brand or maker of it, the only markings on the inside state: “Outer Circle Products LTD. Chicago, U.S. & Foreign patents pending, made in U.S.A.”

I got this case on eBay some time ago. Unfortunately it was painted in the wrong color and had the incorrect details on it, so I had to refurbish it and make it accurate to its prominent appearance in TNG.

Here are some screencaps from the show:

picards_briefcase_ref_1

picards_briefcase_ref_2

picards_briefcase_ref_3

This case was actually also heavily used on “Star Trek: Deep Space Nine“, not very prominently however, but in the background on the Promenade. For these appearances, it was repainted and outfitted with different styles of tape detailing.

Here are some examples:

cardie_padd_tnIn “Star Trek”, the idea of the paper-less office has been perfected. No pieces of paper, no pens, but only so called PADDs are used to note, capture, save, copy and transmit any kind of information.

Not only humans however use this kind of technology (see Voyager PADD), also several alien races like the Cardassians have realized the comfort of easy to use mobile information management. What I have here, is such a cardassian PADD, which was used primarily in “Deep Space Nine”. I was fortunate enough to add this piece to my collection by winning an eBay auction.

By the way: Although this PADD was designed to be a cardassian device, it was later repainted and also used as a Federation PADD!

First up, here’s a close-up shot from TNG for reference:

tn_voy_padd_sHow do you build a PADD? Well, it’s easy, if you have the right kit. In this tutorial I want to show you how to build up one of Matt Munson’s small Voyager PADD kits. Although he claims to build these is under an hour, I would recommend to take a little more time…

Matt’s PADD kits contain three black acrylic plates which have been precision cut with a laser using the accurate shapes traced from an original prop. The thickness of the plates is also correct (3 mm).

Along with these plates I got a set of graphics for the display and the control buttons. I also got another display graphic so I could choose my favorite one. Furthermore, there’s a sticker of brushed aluminum vinyl included for the big button in the right control window. Looks sweet!

Here are all of the kit pieces at a glance:

buildup_voy_padd_s_4415

There is a protective paper backing on the acrylic plates. This is a necessary part of the laser cutting process.

This paper has to be removed first, but only on the “inner” sides of the front and back plate:

buildup_voy_padd_s_4418

buildup_voy_padd_s_4423

These are the two plates without the paper. Note that the right (front) plate is lying on the table reversed showing it’s “inner” side.

Next these plates are carefully glued together so that they are perfectly aligned to each other and the edges are flush. This is just a temporary fixation and will be unfixed later. So I didn’t use a non-removable glue, but double sided adhesive tape instead.

buildup_voy_padd_s_4425

buildup_voy_padd_s_4426

I left the paper attached to the front and back side to protect them during the next step.

The corners and edges of the PADD need to be rounded. Since acrylic is a pretty hard material, you won’t have much success using sandpaper. For this you need either a dremel with an appropriate attachment, a router or a big file. I decided to use the latter to keep a higher degree of manual control.

This is a rather tricky process. The curvature should be clearly visible, but it shouldn’t be too round. It wasn’t easy to remove an equal amount of material all around and on each side to make it look symmetrical.

buildup_voy_padd_s_4427

The file work is of course only a means to add the bevel to the plates. You won’t be able to get the surface smooth that way. To achieve that, I used sandpaper going from lower to higher grit numbers. This works best using wet sandpaper under running water!

During sanding I then disassembled the two plates to also sand the “inner” edges slightly – not to round them, but to remove flashes left over from the laser cutting process.

Finally, I also removed the paper backing to check the curvature of the two plates and used sandpaper to do corrections.

buildup_voy_padd_s_4428

Here’s the result of my work with file and sandpaper:

buildup_voy_padd_s_4429

buildup_voy_padd_s_4433

Next up is priming the PADD.

Since the plates are later glued together, the areas where the glue will be applied need to be masked. This is done because glue attaches itself more easily to “naked” acrylic than to primer or paint. This way you won’t have to use sandpaper later to rough up the surface.

buildup_voy_padd_s_4435

To prime the pieces, I placed them on paper without suspending them in any way! This way I didn’t have to worry about overspray getting on the other side of the plates and making them look ugly. I didn’t prime the edges in this step because they could get stuck to the paper.

buildup_voy_padd_s_4447

When the primer was dry, I turned the plates over and then did suspend them on small blocks of wood. I primered the pieces again and also applied some to the edges. Because the plates are suspended, they can’t get stuck to the paper and I don’t have to worry about overspray because most parts of the inner side will not be visible.

buildup_voy_padd_s_4453

I repeated this step with my Plasti-kote 7173 equivalent spray paint,  suspending the pieces when doing the outsides and laying them flat when doing the inner sides.

Next up are the graphics. They have to be cut precisely to fit inside the windows of the front plate. This requires some patience.

buildup_voy_padd_s_4458

Also the brushed aluminum vinyl sticker has to be applied to the gray area on the bigger control graphics using a pair of tweezers. The sticker has the exact same size as the rectangle and is not removable, so I had to be very precise!

buildup_voy_padd_s_4461

buildup_voy_padd_s_4464

Once the paint has dried, …

buildup_voy_padd_s_4467

… I removed the tape from the inner side of the plates.

Now all the parts have to be assembled. I used 5-minute epoxy glue to join the acrylic plates together permanently. Be careful with this stuff and always wear gloves to avoid glueing your fingers together!

First, I removed the paper from the middle plate. No additional work is necessary on this one. Then, I glued it onto the back plate like so:

buildup_voy_padd_s_4554

I had to be careful to align the smaller plate correctly (the shape is not symmetrical) and to place is exactly in the middle of the back plate. I used the working time of the 5-minute epoxy glue to correct any errors.

Next up is the front plate which is glued onto the middle plate. Again, careful aligning of the edges is in order.

buildup_voy_padd_s_4557

The last step is to apply the graphics. They are self-adhesive so you merely have to peel them off and place them where they belong:

buildup_voy_padd_s_4558

That’s it, the PADD is finished!

Bottom line: A very inexpensive prop that is quickly and easily built and looks just plain cool lying on a desk!

tn_tng_cricketI got this small prop in kit form from a fellow ASAP member. When I first started this project, I thought that such a small object could not be a lot of trouble during buildup. The exact opposite was the case. It took a lot longer than I anticipated to get this one done. I also had to do a lot more research than I had planned.

The Type I personal phaser was used in TNG whenever a seemingly peaceful situation didn’t require larger weapons or when a potentially dangerous away mission needed discrete protection, for example diplomatic negotiations. During undercover operations such a small weapon can be useful as well.

tng_cricket_4371

Gene Roddenberry, the “inventor” of Star Trek, always considered the “cricket” phaser as a symbol of superior 24th century technology. It illustrated for him that great energy and with it great power doesn’t have to be contained in a large and terrifying housing. Roddenberry also gave this phaser the nickname “cricket”.

tng_cricket_4373

There are two variants of this prop: During the first season of TNG, the phaser was painted completely silver, had dark particle vents and a dark blue thumb pad. From the second season on, the case was designed more colorful and interesting. This variant is what can be seen here.

tng_cricket_4376

Unfortunately, the use of the Type I phaser was ceased soon because of technical difficulties. Since this is such a small weapon, it was nearly not visible on low-res TV screens when fired. Because of this, the phaser beams sometimes seemed to come out of the actors hands, which – in the opinion of the studio executives – would confuse the viewer. Therefore it was suggested to use Type II phasers only from this time on.

I didn’t just paint the muzzle red but actually inserted a dedicated muzzle piece.

The last time this type of phaser was used was in the fourth episode of Voyager’s fifth season: “In the Flesh“.

tn_tng_cricketThe Type I phaser from TNG, a prop barely 9 centimetres long. To do a replica of this can’t be much trouble, right? Wrong! The smaller the object is, the finer are the details and the more time has to be spent to make the prop look good. I will describe here what I did to build this “cricket” phaser up. When I got the kit from a member of the ASAP board , it was in a pretty raw shape, which is not uncommon for resin castings however. This meant that the surface had to be smoothed out (especially on the sides), pinholes had to be filled and even certain areas of the body had to be reshaped:

buildup_tng_cricket_3137

buildup_tng_cricket_3139

buildup_tng_cricket_3141

As a special feature, this kit allowed you to take a look inside the phaser. To implement this into the finished replica, the builder is supposed to cut a piece of styrene to fit as a thumbpad which then could be slid out to reveal the “circuits”.

buildup_tng_cricket_3145

buildup_tng_cricket_3148

Note the two struts at the rear end of the body. They are caused by the resin being poured into the mold and also getting into the air vents that probably had been created to allow the air to escape as the resin was poured. They of course need to be sanded off.

Another thing you can see in this picture very well is that the sides of the casting were pretty raw. This was probably caused by the seam line running here, which is inevitable with all two part silicone molds.

buildup_tng_cricket_3157

This is after the first filling work was done. I filled the defects on the sides using polyester putty and sanded it down. Also the first splash-coat is already applied here. It revealed where I had to do more repair work.

buildup_tng_cricket_3158

buildup_tng_cricket_3160

buildup_tng_cricket_3163

As you can see, the muzzle of the phaser was originally solid and supposed to be implemented using paint only. However, I had other plans for it. More on that later though…

buildup_tng_cricket_3178

buildup_tng_cricket_3179

I then filled small holes and imperfections using spot putty. Don’t apply too much of it unless you want to make the sanding process any more difficult than it has to be.

buildup_tng_cricket_3207

The phaser during priming. Several thin coats are in order to prevent paint running down the body.

buildup_tng_cricket_3216

Here you can see the controls. They are nothing more than styrene cut and sanded to shape to fit into the respective recesses on the body.

buildup_tng_cricket_3215

Fits like a glove!

buildup_tng_cricket_3394

buildup_tng_cricket_3395

buildup_tng_cricket_3396

Next up was the cover for the “inner workings” of the phaser. After I had cut a piece of styrene to fit the designated area, I realized that it didn’t fill all the gaps present. Also, there was no way to make it fit in perfectly and keep the functionality of sliding it out.

Because of this, and because there was never seen a open “cricket” phaser in TNG or elsewhere, I decided to seal the thumb pad using putty and to make a solid prop out of it:

buildup_tng_cricket_3399

buildup_tng_cricket_3401

Sanding all of these edges and corners smooth was a challenge, especially because the corners were supposed to keep their curvatures.

buildup_tng_cricket_3403

buildup_tng_cricket_3407

buildup_tng_cricket_3489

Here’s the result of several puttying and sanding passes. The remodeling of this area was extremely elaborate and required a lot of patience.

After I had applied a coat of primer here , I realized that the area of the thumb pad was too small and also that the recess of the cover was too deep. So, I repeated the last step and cut another piece of styrene to fit. Then I once again had to use putty to seal all the gaps.

buildup_tng_cricket_3827

Here’s the final result after the last coat of primer:

buildup_tng_cricket_4107

buildup_tng_cricket_4108

buildup_tng_cricket_4110

The rear end required some effort, too. I had to join the pieces of styrene with the resin body to make it look smooth and “natural”.

Now back to the muzzle: As I said, I had a special plan for that. Instead of simply painting it red, I wanted to insert a seperate piece as an emitter. I thought that would look more authentic and I also used this picture from “Star Trek: The Next Generation – Technical Manual” as a reference:

buildup_tng_cricket_4111_tech_manual

So, I took a small round file and removed some material from the front of the phaser until I thought it looked right:

buildup_tng_cricket_4113

Next I shaped the muzzle insert from a spare piece of resin. It nicely re-completed the forward shape of the phaser and fitted inside the opening very well. Since we’re talking about very small sizes here, the task of modeling the muzzle was not an easy one. My own fingers often were in the way holding the piece of resin.

It would have been nice to do the muzzle piece from a translucent red material, but I decided not to pursue this because the muzzle should have the same appearance as the particle vents on the pre-fire chamber. Since there was no way to do them transparent on this build, I chose to do the muzzle piece opaque as well.

buildup_tng_cricket_4114

buildup_tng_cricket_4115

Here’s the emitter being test fitted into the phaser body:

buildup_tng_cricket_4118

buildup_tng_cricket_4120

buildup_tng_cricket_4121

buildup_tng_cricket_4122

Now all of the seperate pieces were finished and I could move along to painting them!

First I painted the phaser body using the standard color for Starfleet equipment: Plasti-kote 7173. This paint is of course not available in its original form in Germany and that’s why I went to a spray paint specialist and got me the accurate color custom mixed using a color sample of the original paint.

buildup_tng_cricket_4157

All of the areas that are not supposed to come in contact with the paint have to be masked off before spraying. In this case I masked the recesses of the controls so that the coats of paint won’t make them smaller to make sure my buttons would still fit in there later.

Just with the primer it’s extremely important to spray several thin coats instead of one thick layer of paint. It’s alright if the primer is still visible after the first coat! With the subsequent coats the paint then becomes more and more dominant until the surface is perfectly covered. Between coats you should wait 5 to 10 minutes to let them dry.

Try this trick to avoid ugly paint blobs: Place the can into warm water for a few minutes to heaten up the paint. It then disperses a lot finer.

buildup_tng_cricket_4200_coats

Here’s the result:

The second color was next: Bronze. Again, I masked all the areas except the thumb pad. To help attach the masking tape I sometimes use toothpicks in tricky situations. It’s important to stick the tape very tight onto the surface to prevent paint from getting under it which would make the paint line look messy.

buildup_tng_cricket_4232

Everything but the thumb pad had been masked off:

buildup_tng_cricket_4233

The power bar was also ready to be painted now. This piece of styrene is merely 25 millimetres long and the strips of masking tape were 1 millimetre thick. Masking this tiny thing required some patience.

If I were to do this today, I’d probably use a printed graphic instead of painting styrene…

This is the phaser after the second color had been applied and the tape had been removed:

Very nice!

buildup_tng_cricket_4270

These are all the finished greeblies: Muzzle emitter, power bar, control buttons and the trigger. I glued golden paper onto the styrene control buttons to make them neither too glossy nor too dull. Then I used a black marker to paint the sides. The trigger is also styrene painted silver.

buildup_tng_cricket_4365

buildup_tng_cricket_4367

Several masking and painting passes later the forward part and the muzzle of the phaser were finished. It still looked quite unfinished though.

Next the greeblies had to be attached. The emitter had to be inserted into the muzzle, the power bar and the control buttons had to be glued into the appropriate indentations and the trigger had to be attached to the thumb pad. To provide the glue with a better grip to bite on, I carefully roughened up the respective surfaces using sandpaper.

Now only one other thing was missing: The particle vents on the prefire chamber. A lot of replicas show them to be angular. However, the originals always had straight vents. To make my phaser as accurate as possible, I of course decided to make them straight as well. On the top and bottom side, there are one large and four small vents each. On each side there are three of them. Originally I wanted to put them on using red paint. It then however became clear that red vinyl tape was the better solution for this. It is less error-prone and also looked better.

And here is the finished phaser:

Although there are some things that I could have done better in this build, I’m still very satisfied with it.

tn_sonic_driverIn this tutorial I will describe the process of building one of my resin Sonic Driver prop kits. Though it’s a relatively simple kit that essentially just needs to be painted, the partially complex shape of the prop can make the preparation work quite tricky and requires some expertise.

The kit consists of the resin cast body and some tape which is added in the end. And that’s all there is to it, really.

tutorial_sonic_driver_3121

Here are some detail shots of the casting:

tutorial_sonic_driver_3130

tutorial_sonic_driver_3129

And here is a picture of the original for comparison:

sonic_driver_ref_2

When I first tried to cast this prop up, I had a lot of trouble with air bubbles in my castings. Then I learned how to improve my technique of mixing the two resin components by adding them together and then pouring them from one cup to another several times instead of stirring them. So, very few air bubbles were left to be filled.

To fill the bigger holes I used a two-component polyester putty which is normally used in the automotive sector. It cures very quickly (within 30 minutes) and can be sanded very easily.

Here are two of the biggest bubbles already filled:

tutorial_sonic_driver_3132

tutorial_sonic_driver_3133

Next is sanding. This is the most elaborate step in any prop building project. You will spend a lot of time grinding and sanding. So, sandpaper is essential here.

Remember to “go through the grits”. This means that you should start with a higher grit sandpaper to roughly shape the object and then move to lower grit numbers to make the surface smooth. Be careful not to remove too much material in the beginning, because it’s much easier to remove a little more instead of adding something.

In the next picture you can see that I used a high-grit sandpaper to process the larger air bubbles first. The hole is still visible. Also, there is still putty which doesn’t belong there.

tutorial_sonic_driver_3136

The tip of the instrument is next: Here I also filled a smaller air bubble and sanded it smooth going from high to low grit numbers.

I decided to drill a hole into the tip, because that’s how it is on my original aluminum prop. Also, it adds a lot of authenticity.

tutorial_sonic_driver_3152

Sandpaper is not only used to sand down any left over putty, it is also necessary to remove other flaws that resin castings might have, for example the seam line. It occurs along the body where the two mold halves meet and is inevitable. Certain professional casting techniques however can reduce the seam line to an extent where it’s almost not visible anymore.

Reality is, that you should inspect every square centimetre or even millimetre of your prop and process it with sandpaper or putty. Sometimes however, sandpaper is not the first choice, for example when it comes to fine details or structures. In this case you should have several different small files handy to handle that.

For bigger kits or larger areas you can also use power tools like a belt sander. But be careful: These tools don’t allow the same control over your work as a manual job does. Before you know it, your project could be ruined because you removed too much material or you slipped and damaged something. Also, the risk of injuring yourself is a lot higher, so take the appropriate steps to protect yourself!

Now, if you think that the prop surface is smooth and you repaired all of the defects, apply the splash-coat (a coat of primer) to reveal any previously invisible imperfections: scratches, blemishes, pinholes.

tutorial_sonic_driver_3165

tutorial_sonic_driver_3167

tutorial_sonic_driver_3168

Allright, there’s still a lot to do here!

To remove such small defects, I use a spot putty. It’s not necessary to mix it from two components which makes it very easy to use right out of the tube. I chose to use a red spot putty because it’s easily visible during the application as well as during sanding. Since it will be painted over later anyway, it won’t affect the final finish.

Here you can see the areas covered with spot putty:

tutorial_sonic_driver_3169

tutorial_sonic_driver_3170

tutorial_sonic_driver_3171

After I had applied spot putty to every visible scratch, pinhole etc., I then again used sandpaper to once more remove any excess putty by “going through the grits” until the beige color of the resin becomes barely visible again. However, don’t take off too much – you don’t want to change the overall shape of the prop.

This is how the result looked like:

tutorial_sonic_driver_3174

tutorial_sonic_driver_3175

tutorial_sonic_driver_3176

tutorial_sonic_driver_3177

Now, another coat of primer was in order. After it had dried, I again took a hard look at every part of the prop. Normally there are still pinholes etc. left after this “second splash-coat”.

This is repeated until the prop body is absolutely perfect. Of course, the term “perfect” depends on what the person who is building the prop is regarding acceptable. Me, I’m a perfectionist and I probably do this way too often. Remember: The final coat of paint doesn’t hide any defects, but makes them even more visible!

A very important aspect here is patience. It can be quite unnerving to apply another coat of primer only to discover that there are still scratches or pinholes left. However, once they are all repaired, you can tap yourself on the shoulder knowing that you did everything possible to make the prop perfect.

tutorial_sonic_driver_3224

Now that the surface was completely flawless, I could apply the final coat of primer. One last checking look: Is there still a… No, thank god it’s just a shadow!

After the primer had completely dried, I moved on to the paint. I used a chrome paint containing real aluminum particles to create a highly realistic approximation. Silver spray paint is also suitable for this. A little trick helps to prevent ugly paint blobs: Place the can in warm water for ten minutes. The heated paint will then be dispersed a lot finer.

One precept of painting is to apply several thin coats and let them dry before applying the next instead of spraying one thick coat. It’s alright if the primer is still visible after the first coat! Be patient, even if you want to finish the prop soon. You don’t want to ruin it during the last step by causing “paint noses” occurring due to too much paint, do you?

tutorial_sonic_driver_3226

Once the painting process was finished and the paint was dry (again, you should rather wait a little long than ruining the prop), I could add the greeblies which was the last step in this buildup.

In this case, the greeblies are nothing more than differently colored grip tape cut to shape and attached at the correct areas (see illustration).

sonic_driver_illu

tutorial_sonic_driver_3230

The last step is to paint the tip golden. Of course, I had to mask off the rest of the prop to protect it. I used crepe tape for this because it can be removed easily. Anyway, to avoid any risk of damaging the base paint, I only masked a small area at the tip and wrapped a paper napkin around the rest of the prop.

tutorial_sonic_driver_3370

tutorial_sonic_driver_3374

The prop is finally finished! Here’s how the result looks like:

tutorial_sonic_driver_3379

tutorial_sonic_driver_3381

Here are some comparison shots I did with the original aluminum version which served as a master model here:

tutorial_sonic_driver_3383

tutorial_sonic_driver_3388

tutorial_sonic_driver_3391

There’s almost no difference visible on the pictures. The chrome paint is not quite as shiny as the real aluminum, but that was to be expected. Unfortunately it also tends to get even duller when handled.

Anyway, I think the result is very good and satisfying.

tn_sonic_driverSince I’m a big fan of engineering tools that are used by LaForge, O’Brien or Torres to repair the ship, I’m always looking for adequate reference material to extract some useful information.

Because of this, “Star Trek: Captain’s Chair” is a true treasure chest for me as well as probably for many other prop enthusiasts. This software enables you to not only move freely on the main bridges of the Enterprises 1701, 1701-D, 1701-E, the Defiant and Voyager, but also to look at all of the control panels, use them (!) and have a look at several props that are lying around. There are 360° panorama views of above mentioned rooms and all of the props so that you can look at them from all angles.

In this manner, I found the Sonic Driver lying on the rear work table on the Defiant’s bridge next to a hand phaser, a phaser rifle, several PADDs and some more tools:

sonic_driver_ref_1

sonic_driver_ref_2

I’ve always liked the look of this tool: A Simple, symmetric shape and a very high-tech appearance intensified by glossy metal.

To keep that look, I decided to do a replica of this prop entirely from metal. Aluminum was the logical choice for that since it is relatively soft and easy to work with. The first step was to have a look at the Quicktime VR file and to study the side view of this prop. Next, I translated this information into an illustration showing the outlines of the general shape with all its details. Then I added some colors to the drawing and supplemented it with “virtual greeblies”. Finally, I rendered a 3D view of the prop to evaluate its overall appearance.

sonic_driver_illu

When I was satisfied with the result, I took this data to a local machinist who converted the template into a real metal body and turned it from aluminium with great precision.

To finish it off, I then applied some carefully cut grip tape and some golden paint to the tip.

And this is how the end result looks like:

sonic_driver_2767

Being made from solid aluminium, the prop has a nice weight to it…

sonic_driver_2771

…and is cool to the touch…

sonic_driver_2772

…just as a real heavy duty tool should feel!

Note the picture subtitle in “Captain’s Chair”: “Measure tetryon particle flux fields”. I’m sure I’ll find such a field somewhere around the house… 😉

Note: I made a silicone rubber mold from this prop to cast resin copies of the original. Here is a link to a tutorial on how to turn one of those castings into a prop.

tn_padd_stylusThis is one prop I got entirely by accident. While watching “Nemesis” once, I noticed that Picard was using a kind of input device to enter data on a PADD.

A closer look revealed that this prop was nothing more than a pen-shaped butane torch with some golden vinyl tape added to the handle. When I realized that, I remembered that I had something similar in my workshop lying around for years. When I finally found it, it was exactly the same!

After I cleaned it up and added the necessary tape, it looked just like the screen-used stylus and I had another accurate prop replica in my collection.

Common objects, slightly altered for use as a prop are called “found items”.
