Mr.P did your crank grinder dial off the mains or did he go off the seal and the gear? Reason that I'm asking is that I sent 3 cranks back last year that had a 0.020" runout on the gear. (340 mains)

if the machine has chucks, you go off the seal area, not the mains. on certain cranks we change over to centers. can't get any more true to the centerline than that.
i know scat had some issues awhile back. i think it might have been Ryan J that said he wasn't going to use them anymore. i'm sure he'll correct me if i'm wrong.
we've literally used and sold pallets of K-1 cranks and rods and out of all those i've only ever had one with an issue that was actually pretty minor. no matter, they propmtly replaced it and ate the shipping both ways, as they should.
don't even want to get started on the problems with the eagle cranks throughout the years.
(DISCLAIMER)we sell all three of those brands, so there is no bias in my reply.
