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

I am not proud, I just have too follow thru, I am not quitter; it's hard for me too believe someone already figured out the physics between twist force/ spring length and material and friction of cyl wall / tool contact resistance...and what's $200 - $300? If I even succeed or don't?
