Hood,
SS is still in the old pc and I'll get around to installing it in the new one. I am also curiuos.
Just been focused on trying to improve threading when using the PP with a single pointed tool. Comparitively, using the SS would be an apple and not an orange.The file I recently posted about lead error says it all. I am also curiuos, if as shown by changing the feedrate, if it will hold true for long threading. That was like zero for a 2" length, which implies, 4" of threading should work fine. The long thread would magnify any lead error.
On the practical side of things, in all these years , i have only needed to do very accurate threading to 6" or so and that was for replacing a screw and nut in crossslides. The screw was matched to the nut and was done with a manual lathe. I am hoping that we can refine PP threading to equal a manual lathe. For threading it would be per the
file i posted.
BTW, this testing is not about "Rich's" threading. It's in light of the typical hobbiest that will use Mach threading with
a low end CNC system ( if that is a way of saying it ). It will be nice to be say to a user, with confidence, that his problem is the lathe system.
Any suggestions appreciated, as more viewpoints are a lot better than one,
RICH
