OK everyone it's a cast crank.I have not ground any crankshafts Hoosie,but gotta ask ya in post 5 you said u "had a crank like mine with no radius"u got the required fillet with just a .030 cut,that .015 each side.I just measured the height of a good main and it was .060 tall.So gotta ask how can that be possible with only just a .015 cut u arrived to around .060 tall fillet?

If it’s a cast crank the ONLY option you have is to have it ground to 3.000 crank specs. I’ll let you know when I can find a REASONABLE machine shop to produce shims. .060 fillet? Well, what that says is you were going to have one hell of a time fitting a crank on bearings NOT manufactured or modified to run that much of a radius. What does your radius gauge indicate? You have a radius gauge to check the radiuses, yes? What you need to understand about grinding the radius on a journal is the perimeter of the cutting wheel is used; the radius does not cut the journal. Unless you “bump” the stone on the cheeks of the journal toward the end of cutting the journal you will end up with a parting line between the journal and the fillet. If your machinist went overboard while cutting the radius on the grinding stone you could have a .060 fillet. I would seriously question whether you can trust ANY of their machine work.
