Tap Plastics has their line of RTV mold rubbers(both urethane and silicone)as well as other brands I believe located throughout the bay Area nd a few places out of state on the north coast.Douglas and Sturgass is an art supplier in the Bay Area that carries a variety (they do mail order) as well as ...

I would say that it would need to be thinned more aggressively,but I've never used "Future Floor Polish" before and don't know how it performs/reacts?With paint,the thinner you can reduce your paint,the lowere the psi you can use.Something I've been strugggling with when using hobby enamel...

So, if you use this "servo" you can program it to start and stop in different positions?How many?It can only store 4 minutes of memory,am I understanding this correctly?The only other obstical aside from being able to grasp the concept of servos is the mechanics to make the wings move. I w...

I've read how the Aztec brushes have a really simplified maintenance.I liked that part,but don't really know how well they perform?The Pasche VL I have has a #3 needle I think?I don't think I could get a smaller needle for that brush,maybe a #2 needle,or it wasn't recomended for use with acrylics,la...

Many thanks guys for getting back to me on this "off" subject.The only other real hurdle is developing the physical mechanics to achieve the motion.I know virtually nothing of electronics,a sad subject for me to admit to.I hadn't really thought of servo's as an option,and radio control is ...

mecanization with electric motors/gearing?

I was wondering if anyone out there has any experience with stepper motors?I have a completely crazy idea that I'm considering to try,and that's animating wings on a large scale model.I have been attemptintg to learn about stepper motors but really...I find myself more and more confused. The kit I h...
