That Hughes guy is one lucky dude.Technically started the one on the right yesterday and finished both this morning. After seeing a post on here, I decided to build a dedicated crank measuring stand with dual indicators. Came out pretty nice. Made one for Hughes while I was at it. Nice brake from building boats.

In the lathe chuck with one end and tap the other with a lead hammer, usually .008 or so.Very nice, how much runout do you typically see at those points on a new crank? How the hell do you get it straight?
This is the main reason I don't want to run the "RS" style nitro motors, that and having to pull the crank apart to change the rod bearings.
Terry, I shoot for under a thou. Zenoah cranks are mostly ok new, but I have found them 3-5 out. I have a very precision jig for assembling them that I got from Lohring. If it is too cold in the shop the plates bind on the pins.Very nice, how much runout do you typically see at those points on a new crank? How the hell do you get it straight?
