Epoxy and machine building....
I don't think you can just use any old epoxy. Some of them shrink
quite a bit when curing. Turcite, Moglice, and Belzona are resins that
may be used.

small lathe cast in resin.

I've been looking around the net for information on how epoxy/granite
machine bases are formulated. So far I have come up with very little.
I'm going to attempt to make a smallish mill with a somewhat homebrew
epoxy formula. If anyone knows anything about these sorts of things
feel free to speak up.
For the base material I'm using the folowing formula:
First I will use quartz rock etched with a moderately strong HCL
solution.
The stones will consist of 1/2 to 1 inch stones.
For fine filler I will try a mix of 90% quartz sand and 10% carbon
fiber.
All the agregates will be soaked in silane and dried before being used
as filler.
For the mold I will use varnished wood. The steel dovetails will be
set directly into the epoxy plum.
Some problems I have a
Where can I get 2 or 3 gallons of epoxy and enough hardener?
I need to find some cheap ground dovetails.
I am probably going to need to make a couple small test batches. If I
cure the epoxy under heat and vacuume is there anything I can use to
seal it to reduce water uptake?
Anything else anyone can think of?
