I want to try to cast a headstock for a lathe in epoxy granite. I havent done alot of work in eg so i thought i get your input on a few things.
The headstock i want to cast is basicly just a big slab with cast in flanges back and front for a cartridge spindle and a rear bearing, no gears or anything like that on the inside.
Like this only bigger, http://www.toolsandmods.com/images/m...spindles-5.jpg
What wall thickness would you go for at the narrowest point, that will be the sides where the bearing houseing for the spindle sits? And what max aggregate size would you chose?
