Thread: Working with Foam

Well, here's what you could do instead. Make the part out of foam. Make it to the exact dimensions that you want the final part to be... THEN! instead of trying to reinforce the foam, build a box around it and fill it with RTV silicone! Then you can fill it with your favorite urethane and paint it, machine it, make a billion of em for that matter. If you want, check out www.smooth-on.com They have all kinds of wonderful castable plastics.

BuT, if you don't want to bother with all that, then yes, you could just offset your boundaries and laminate glass over it. I'd advise looking into vacuum bagging too because chopped mat and wet-layups are just asking for rough finishes and air bubbles, especially in small parts.

I could go on for hours with any of those reproduction methods, or some others i didn't mention, but let me know what you're interested in and we'll talk.

those smooth-on products rule! i've used a few of them with great results!

I like the way that looks.

I have read the thread. Not sure I want to go.
Thanks though.

Nice write up on the process. It certainly gets one thinking about the potential uses of foam.

i've spent alot of time making parts out of it. I'm pretty excited to see what the possibilities are for mold-making and production. I'll probably do another write-up when i finish my alumilite version of the trim bezel.
