[Noisebridge-discuss] Who wants Kilograms of Shapelock?

[Lee Sonko]

I'm in for $10 at up for $15/kg
 
I'm trying to find a better material to use for the Mechanical 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.

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. 

Anyone who knows of a source, please help me out.  Right now I am looking to
work with Tri-ISO.


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.

Ripped from http://en.wikipedia.org/wiki/Polycaprolactone :

PCL also has many applications in the hobbyist market. Some brand names used
in selling it to this market are Shapelock and Friendly Plastic in the US,
and Polymorph in the UK. It has physical properties of a very tough,
nylon-like plastic that melts to a putty-like consistency at only 60°C.
PCL's specific heat and conductivity are low enough that it isn't hard to
handle at this temperature.This makes it ideal for small-scale modeling,
part fabrication, repair of plastic objects, and rapid prototyping where
heat resistance isn't needed. Though molten PCL readily sticks to many other
plastics, if the surface is cooled, the stickiness can be minimized while
still leaving the mass pliable.
