That's the plan at this point. Just trying to figure out how to accomplish it. Sometimes I wonder what I've gotten myself into. Then I remember if it was easy, everyone would be doing it!

What I'm planning is to make a tapered ream to cut the appropriate taper in the stacks. It's a fairly slight taper but matches what I've read somewhere (David Vizard perhaps?) as optimum, around a 2% taper I think.

I'm not sure at this point if I'll have to first bore the stacks with a few parallel steps then ream, or if my planned ream/cutter will do the entire cut in on motion. The difference in time between the two methods would be measured in days....
