Thanks for good advice. Keep it coming.
Muskrat, your suggestion last time I did shimming has, so far and with much wood knocking, worked well. Specifically clamping bearing and shims against web with cush nut while Loctite sets.
Coater, I don't think my machinist, Custom Engine Services of Aurora, IL, is spending much time on doggie door hinges, or the like, but your advice to state the goals is good. I will be asking for 1.5 -15 thou end play to give them a challenge while keeping it affordable.
On ovality, my small bore gauge turned out too small and my large too large to measure the bushing bore. This left me with telescoping gauges. Using one of those it appears the bore might be 1-1 5 thou oval. Might not matter because new bush is about 4 thou bigger than old bush and about 6 thou bigger than the bore. That, I believe, amounts to an oversized bush. I think I should ask machinist to just round the bore and turn the bush for the right fit after the heated case has cooled. I am assuming he will heat the case to install the bush, just like we would.
Wow, I hope a couple of our machinists have read this far and will tell me if my plan is good.
