Would someone please point me to a link that describes this, or outline the steps:
(I'm assuming "squaring up" is the right term for round bar.)
I have a piece of very rough aluminum round bar, 2" D x 4". Ultimately I want to part off a couple of 3/8" disks, diameter isn't crucial. I haven't touched my lathe in months and what I was trying last night--and apparently my brain--wasn't working.
