What about the taper on the registers. I know ultimately one wants zero.. but as the stones go back and forth doesn't that crown it a bit? And when using steel caps procedures as the materials are different. Especially when line boring as the cap is harder than the block.Or for locking down the caps so they can't move when using studs..
Years ago when I had a girdle done to my TTA, the machinist I used instead of using the shims made the spacers. As the shims would "squish".
Glad I posted this thread. Extremely interesting. Thanks guys for the replies.
