Work In Progress: Neutrino Probe – Main Parts

After my efforts of starting a Neutrino Probe replica were suddenly brought to a halt last week, I couldn’t do anything but wait for my Dad to repair the lathe which had broke down on us. Fortunately, he was able to find a new capacitor quickly and replaced it in no time at all. So, we could schedule a new session to get back to work. This time, there were no interruptions and I was able to continuously work on the three main parts for two days.

Even if I had to deal with a few setbacks, the work went forward quite smoothly and pretty much the way I had imagined it. However, some serious precision work was necessary to make the parts as accurate and clean as they turned out to be, which was no easy task at all! As you can see in the pictures below, I shaped the wooden raw material with knives, saws, files and of course different kinds of sandpaper until I was satisfied with the results, while permanently applying coats of primer in between to reveal rough spots and other blemishes yet to be smoothed out. The most useful tool in this process? My caliper, which I used to continuously measure the thickness of the ribs, the spacing between them, etc. Without it, the parts undoubtedly wouldn’t have turned out this nice.

Of course, the pieces are not 100% symmetrical or exactly like my schematics, but I’m very pleased with the results nonetheless. The three parts I made in this manner are the ribbed middle section as well as the two back pieces. I decided to do the latter ones separately so I could make seamless resin castings of them later by using a one-piece silicone mold for each – in contrast to a two-part mold for a bigger piece, which would have a seam line by default.

So, without further ado, here are the pictures. First, the finished parts:

The original prop and my schematics for comparison:

And here are some progress pictures:

Very useful for making flat surfaces truly flat: a belt sander.

Humble beginnings…

Expanding the grooves.

Cutting deeper to match my schematics.

Some filing action to accurately shape the ribs.

Splash coat applied to reveal all kinds of blemishes.

The final cut to trim the piece from the excess wood.

The next part of the probe I want to tackle is the tip of the tool, which I will have to scratch build since I wasn’t able to identify the nose hair trimmer part that was originally used for this purpose.

Work In Progress: Neutrino Probe

Bad News. Today I made my first attempt to use a turning lathe to make the main parts for the Neutrino Probe from wood. For this purpose I went to my parents house where my dad has the required equipment. Well, everything went pretty smoothly at first and while working on a test piece I got confident to be able to shape the wood in such a way to mimic my schematics almost exactly. So far, so good. Unfortunately my efforts were interrupted abruptly when the lathe suddenly broke down. It turned out that the machine used a very old capacitor, which downright exploded in our face. Don’t worry, nobody was hurt in any way. However, the capacitor is useless now and will have to be replaced, which sadly will take a few days. As a result, I’ll have to postpone more work on this project to next week.

For what it’s worth, here’s a look at the test piece I was playing with to get accustomed to working with a lathe:
