Okay, getting serious...Please ask if you have any questions, regarding the build, materials or processes. Any comments welcome.
First up is the mantlet:
The Trumpeter kit has not been designed for recoil, so a sleeve has to made for the barrel to slide in and stay true. Fortunately the kit's gun block's inner diameter is the same as the base of the barrel's OD. I had to cut the ends off the kit part after the halves were glued together and glue in place being careful to make sure everything is straight and true:
Next up is the emitter tube, using stock styrene. Again, it has to be set carefully so it's parallel to the barrel. A tiny bit off here would translate into a huge amount 90 feet away. The pencil mark halfway is where the end of the IR LED is in the tube, it's 9mm from the shallowest edge on the exterior of the mantlet.
I'll probably try to use the holes on the barrel sleeve as the elevation pivot, I'll see after I get the recoil unit set up. I'm using Tamiya's Tiger I unit.
