I wanted to share a photo of my first mould modification with a lathe. This was done with a 3", 4-jaw chuck from LMS, the Grizzly G0765 7x14 mini lathe, and a boring bar I ground from a piece of 3/16" square HSS that 'Perfesser' Keith B. was kind enough to donate to the cause of my general learnin'.
This mould is from 2009, right smack in the worst era of Lyman undersizedness and outofroundedness, so in order to use it at all I had previously fixed both problems via lapping but never was too thrilled with the bevel base when it came to lubing. I have a second, older mould that is near perfect, so this one got the nod for modification. Bottom right is a bullet I cast maybe 6-8 years ago showing the bevel base.
