You guys forgot to mention cutting the ring land at the top of the cylinder if you are going to hone.
Also know that if the cylinder is worn, getting the piston out the top may not be easy since the rings may hang on the land.
Also not mentioned is grinding the rings to get the gap correct, or at least checking it during assembly.
Personally, I have done it successfully, but without experience, there are way too many ways to screw this up. If you are going to all that effort, pull the engine and have the block bored and buy a new set of pistons and rings. If you pull the block and strip it down, the machine shop costs drop drastically. While it is apart, check the rod and main bearing clearance.
