We just got started on a foundry for casting aluminum parts. I can not find anything worthy made from extruded stock in aluminum so we have to make a casting for the CNC machine.

 I'll be making the casting for whoever wants one by the time we finish this project. Here's some photos of the ground work being done.

Over a ton of sand for the foundation. 500# of Sugar Sand #85 mesh for making the green sand and #100 of Bentonite Clay. 70# of Fireclay 4 cubic feet of Perlite and some Diatomatious Earth for parting dust.
