Turn a small drill press into a Bore/ Hone. Bolt it to the top of your engine block & do your own machining .

The time, effort, & $$$ You've pissed away trying to half-*** this isn't going to save You a cent. A lot of Us wouldn't do it, but You could've bought (1) .040" over slug & had the cylinder fixed by a pro, & been done 284 posts ago Dude.....and the cylinder wall won't look like an hour-glass or a snake......or a funnel.....
Sounds all good, but my machine shop and those near by won't bore/ hone just one cylinder...you should have known.
