My Lee 120 TC mould for 9 mm casts .001 smaller than I want and also has a bevel base, a feature I'm not a fan of. I finally got up the nerve to throw it in the lathe and fix these issues.
Have to get it in the 4 jaw chuck and indicate each cavity as you go. Doesn't take long after you get a feel for the process. Getting that feel took me quite a while.
Getting ready to make a cut. The tool was the first step in the whole process. It was ground for a 5/16 inch square bit of HSS. That is an art I am learning, tool grinding properly is truly an art.
Two down, 4 to go.
The final results. The mould is heating, along with the pot right now. Will bve interesting to see how they come out. The burr thrown up by the cutter was removed with a bit of 400 grit paper and followed with a little steel wool.
I have high hopes for this mould now.
