So a buddy just got his late grandfather's mill and lathe given to him, and none of us are machinists by any means. Welders, fabricators, general diy guys, but not machinists. I've got a klr250 dual sport I'm rebuilding, and the cylinder has been left out in the rain a few times. So before I order one, I'd like to try my hand boring. It has a torque plate on the lathe, and power everything. It's old, his grandpa passed in 84, and the stuff is older than that, but in emasculated shape. Looks like it belongs in a showroom floor. This would be my first lathe project. Wondering what I need for the tooling? I know I need a boring bar, assuming I need it to be a bit longer than my stroke? What kind of material? If it goes at all well, I'll also be boring my Harley 883 instead of buying a kit. Plan on tinkering with the lathe a bit before jumping into the bore, but don't think it'll be that bad.
