RE: OT: lost was casting equipment, DIY

Hi Jon

My spring-driven spin caster for the lost wax process turned between 200 and
300 RPM depending on the load (flask size, and weight of material being cast)
it had to turn. If you go to Rio Grande's web site, www.riogrande.com (it's
free) and order their tools and equipment catalog, they have an excellent
picture of a spring operated machine on page 102. They also show a motor
powered one on the opposite page.
