Just about the only thing that RTV silicone will stick to is silicone and it bonds to that like you never saw.

Get a spatula of a different material and all will be well.

The paragraphics things are real. There are actually small tools with little suction cups on them, but they are way larger than teh small parts we are talking abuot.

Like just about everything else in this hobby, the answer is "it depends". If you are glueing on a small part or something that shouldn't need to be held well, then any number of glues will work to hold the part to a painted surface. If you need to part to take some knocks or some loads, then make s...

Here's a thought - drill the holes first, but oversized. Then take some styrene tube and fit it to the holes, taking time to get them aligned. Use thick CA to give you time to move them.

Clear styrene is fundamentally more brittle than coloured stryene, the clear stuff is close to pure while the coloured stuff has numerous additives, only one of which is the colour. I'd reinforce fist and drill second. Also avoid putting too much force oni it while cutting/drilling. That said, I hav...

The answer to all those questions is "it depends" and the solution is to try a bunch of stuff and get experience doing it. Seriously.

Frankly I'd start with 400 grit to get down to a basically smooth surface and then switch to 600 grit to finish it off. It will rediuce the time you are spending hugely.

Re: How do you get that Scratched-Paint look?

I read about this technique where you put down a coat of steel or silver paint and then another colour paint and then scratch off the second paint to see the steel underneath. Which kinds of paints would work best for this type of thing? How do I keep the steel from scratching off at the same time?...

Sounds like it really did take a set when it was made.

If you want a straight barrel (and who doesn't!) I think scratchbuilding is probably your only hope.

If you have a lathe it's not that difficult.

Why not make one as a pattern, eliminate the build lines, cast the puppy in resin and sell them for 1/4 of the price?

Selling parts/models directly from the 3D printer is not cost effective in the least unless the parts are very, very small.

The only real answer to that is "It depends". You haven't even built the vacuform machine yet, so we don't even know if it will pull .030" sheet much less .062 sheet, no matter what the shape.

The thickness of the decals probably isn't too out of scale. A .005" (5 thou) thick brass part equates to a deflector grill that's 4' 2" thick in real life. That feels a tad thick to me.
