it's not me, it's the material & tools, really. [Apr. 11th, 2011|02:26 pm]
Doug Ayen
I spent most of Saturday, and some time on Sunday, working on machining bevels in on the latest set of pizza wheels. The wrought iron, 1095, and whatever that third wheel was worked fine; W2, however, just isn't working out. I get no real machining, the surface just accumulates grooves and looks like crap, as well as not actually machining any material off. Changing feeds and feeds doesn't do anything, I'm at the limits of the machine.

Ok, so I should probably get a better lathe, something that has full torque at low RPM, rigidity where it counts, and enough mass to remain stable under load. Maybe I should just avoid working in W2, despite my having bought 20 lbs of 2" round stock recently.

I'll be checking with the local machinists club to see what I should be doing better, as well as going over my tooling and seeing if anything can be improved -- perhaps I can tighten up the gibs, or maybe I should scrape the ways on the crossslide, maybe I should be using carbide inserts with rounded points. I don't know at this point.

It's never easy. I'm not sure if I'd stick with it if it was, to be honest.
