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

Use a 4" old piston slader it with valve grinding compound to start then use a magnetic drill press on top with a heavy duty honeing head then finish it up with the Lisle 15000 honeing tool at .040" over to fix a bad cyl that got toasted . Skirt going to the machine shop because all the other 7 cyl are in great shape. Unless you just like throwing your money away.
