Nice post. What originally brought me to this section of the forum is that there's some good people to learn from here. I'm still learning. The gift of a line bore job is that you don't have to take material on center, you can take more from the cap side. As far as the bore, how round is round and what's good enough? These choices are made daily by all machinists in every field. If you haven't noticed, part sets are pieced together or if conveniently offered, really freaking expensive for what they are... It's weird how one question opens up a whole can of worms, this is where you have to start off trusting your shop from day one. If you don't think they can work with a particular project (and as a customer you are not always qualified to make that decision), believe me you are $$ ahead even shipping this across the country to be done. With nearly any build at any power level you still have to ask, "How much is in the budget for corrective machining?" Yep, on brand new parts. These things don't always just bolt together. Each manufacturer doesn't always follow a common blueprint. As a shop and as a customer one has to think ahead and realize that problem solving costs $$... yours. From a shop perspective, can you see why offering "crates" solves a lot of hassles? No custy to micromanage you, simply write the check. I think it's been said a couple times here, "arm yourself with info" before you start cutting... Good luck! Tony. Wife calls me "f" sometimes.
