Solsylva has an interesting DIY rotational molding, or casting, machine used for hollow casting of resin or any other material that does not require heat activation. I like their idea of using a rotisserie motor, since I think it is fairly easy to find an unused one for free. Although, a hand crank would work for quick drying resins. – Link

    I’m so glad I saw this. I’ve been trying to figure out how to build a rotating rig for cleaning and coating the inside of rusty motorcycle gas tanks. This is exactly what I need.

    Great! Don’t forget to take some pictures when you are done, and sent them in.

    David (aka solsylva) also has plans for several DIY CNC machines. See the forums on http://www.cnczone.com to find people who’ve built from them. I built the belt drive CNC and am quite happy with it. You can see some video at http://www.youtube.com/cncron39
