I'm working on a model engine here that needs a pretty straight 1/8" dia. piston rod. I have several choices here but the best one runs out .003-.004 over about 2". I tested it in a 3c collet, and proofed the setup with a gage pin which shows less than .001" @ 1.5" stickout. If I could thread the gage pin, it would be perfect.
So, you guys think drill rod would be the best choice? Something else?
Thanks in advance TC
