Well Chris, I've found that I have many of the components needed for a spin caster already. About all I lack are the motor and speed controller. So, in light of this revelation, I'm going to build a spin caster. Here are a few of the things I've been looking at:

The first is the most important to me. A few of the others pertain mainly to casting in resin, but show mold (mould) construction as being fairly straight forward. My goal is to construct a workable set of BT-7 tracks from tin or zinc alloy, zinc being the better choice. Although it melts at a higher temp, some zinc alloys can be nearly as strong as cast iron. It's also much cheaper.

Not ready for another project just now. Paul H. you don't have to get that fancy if you want one. you can make one simpler than that. pretty much make one like an upright disc sander, but just secure your molds to the disc rather than sand paper. so build it onto a bench. and for a splat shield, an old cardboard box will do, just cut out the top and bottom of the box and set it over the spinner, give the motor some juice for a second or two (just to get it spinning), then pour Chris, Odyssey Slipways ------------------------------------------------------------------------------ A Good Credit Score is 700 or Above.
