So, here's what's new, lol. The power feed on my lathe has so many issues I don't know if it's worth trying to fix (multiple gears broken and I can't even get it to change gears on the 3 levers on the face). So I had this idea of fixing a small electric motor to the tail end of the feed screw. I found another guy that did that for the same reasons and he used a windshield wiper motor, a very large one, that has a 60:1 worm gear drive. So got the biggest wiper motor I could find, a pwm controller to adjust speed, and made an adapter to fit the lead screw and viola! I now have power feed! It isn't as precise as I'd like it, there's a threshold if you go slower than it can stall. I have a large stepper motor that want to try and see if it does better. If it's strong enough I should be able to get very precise feed rates.
I got a new cutter for the boring bar. I've been learning about cutters and how they can affect the surface finish. The cutter that came with the bar had a huge radius. Probably a .120 or so for taking deeps i guess. I got one that had a .008 radius and it cuts very nice! Chatter is gone, partly I think form tightening the cross slide gibs. But mostly from the cutter. Only problem now, it is cutting a .003 taper on a cylinder. Which is about 6" long bore. Kind of a lot to hone out, at least more than I want to. So I need to adjust that. I took 3 cuts, .003 each time and it cut the exact same each time. I mounted my indicator on the saddle and had it touching the tool holder, it moved .0005 when it first started a cut. But it stayed there the entire cut. So my crosslide isn't moving like it was before adj. the gibs.
