Work in Progress: Neutrino Probe – Casting

If you know me, then you also know that my blog posts can get a bit lengthy at times. This one, however, I will try to keep a bit shorter than usual. What I want to describe to you however are some of the problems that presented themselves while casting the Neutrino Probe components for which I have all the molds now. Also, I tried a few new techniques with these parts to improve the appearance of the product and make the assembly process easier. What new techniques you ask? Read on to find out. [More…]

Work in Progress: Neutrino Probe – Molding


If you want to make more than one unit of any given prop replica, it is inevitable to make molds of all the parts you need. This way you’ll be able to make multiple resin casts of each piece. For the Neutrino Probe, this presented a few unique challenges I had to tackle along the way due to the special nature of the body, its prototype parts and the fact that I wanted to put electronics in there. In this blog post I’ll show you exactly what I thought would work, what did’t work and – most importantly – what I ended up doing. [More…]

Tools & Supplies: RTV Silicone Rubber

One of the most important materials in the hobby of prop building is RTV silicone rubber (RTV = room temperature vulcanizing). It is used to create molds which can then be filled with casting resin to make copies of your master model. [More…]

Work In Progress: ODN Scanner – Part II (Molding)

tn_wip_odn_scanner_2In this second installment of my ODN Scanner progress report I will describe how the finished master model (see Part I) is used to fabricate a silicone rubber mold which then can be used to cast resin kit parts.

Because the finished prop was supposed to contain an electric circuit with a super bright red LED and five green sequencing lights, the mold had to be done in a way so that the [More…]

Work In Progress: ODN Scanner – Part I (Scratch-build)

tn_wip_odn_scanner_1Welcome to the first part of my progress report covering the creation of my ODN Scanner! In this part I will show you how I scratchbuilt the prototype (the so-called master model) of this prop that I will later cast in resin. Part II and the Tutorial will then cover how I did the silicone rubber mold and how to build up one of the resulting kits. [More…]
