I am almost done with a project of a 4th axis for my tormach. The reason I built my own is I need a super solid 4th for my parts. I started with a super indexer 6" and the tormach 8" kits motor. Almost done and can say not much heavier then the tormachs well mine is 110 pounds total done. But wow what a super solid unit bought it off ebay for the 500 dollar range and it came with everything dividing discs,chuck,plate even the tools to it. I see this same unit all the time for around 1500 dollars. Fully adjustable.
