[Robotgroup] Casting plastics

[Paul Atkinson]

I would be interested in participating in this class/learning exercise also.
I don't have any practical experience molding with resin, although I have
done a few projects with fiberglass and also using silicon (similar to
caulk) to take and make molds.

There is a competitor to Smooth-On called Alumalite that some of the local
hobby shops carry. (If you need instant gratification :-) )

The May issue of Servo Magazine has an article on mold making and resin
casting which might provide some background reading, if nothing else.

Count me in and let me know how I can help!
