Sculpture classes I teach at the Crucible. Right now we generally cut gears,
cams and levers out of foam core. It's easy, safe and inexpensive. But it's foam
core and... well it kinda sucks. If I taught mechanics in metal, we'd spend
all our time learning how to use the tools to work the metal; the same goes with
wood :-(. Maybe Shapelock will fit the bill: easy to work and re-work with
inexpensive tools, safe, inexpensive, fairly sturdy when
cool.</FONT></SPAN></DIV>

<DIV></DIV>Instead of buying the name brand material for $1.50 an oz, I am
looking for a source of CAPA 6800 at $10 a kg or about $0.30 an oz. I
might need to get this in a 20kg volume (that's right, I'm measuring volume in
grams!) That means a $200 purchase. maybe more with shipping and
distributor specific pricing, but I have it on authority that $10 a KG is not
unreasonable.
<DIV><BR></DIV>
<DIV>Anyone who knows of a source, please help me out. Right now I am
looking to work with Tri-ISO.<BR>
<DIV><BR></DIV>
<DIV>Who is interested? Do I have $200 of interest in Shapelock?
Or, how many KG would you like at $10 a KG? The more interest, the
more likely the chance of success.</DIV>
