Any recommendations on a dial bore guage, or an appropriate way to accurately measure the cylinder bore?
Hone to .035 clearance between cylinder and piston (that distance split between the two sides)?
Anyone have tips on honing?
I'll get a scale and balance all rods and pistons.
I've done work on auto and aircraft engines before, but never honed cylinders.
I do have Les' book and will read before proceeding.

Honing is quite basic for what you're doing. You merely need to break the gaze on the cylinder wall to allow new rings to seat. No need to resize the cylinder unless it's badly scored. Then a rebore (not rehone) is in order). The other pistons should have the oversize (if any) stamped on top. Just order a piston the same oversize.
