Precision Ground 1/2" 7075 Rod Supplier

[AdamHeard]

Thanks all, it's a lot of axles, and a lot of mating parts. So, for overall ease of assembly and good running, we'd need some tight tolerance precision ground.

I know Cal Poly has some centerless grinders, we may just buy some 12' lengths of 7075 rod and grind it ourselves (assuming the school lets us).

We have the ability to turn it ourselves or even take rod and "grind" it by polishing with emory paper, but the sheer amount of it would tie up our lathes and machinists for too long.

Mcmaster is the last options, as we'd need 10 72" lengths. I'm assuming a supplier would cost half that.

Eric, it's all for this year
