I'm experimenting with cutting a 3/8-10 ACME LH leadscrew. I can't find any documentation on how to grind the toolbit. "How to run a lathe" gives next to nothing on the bit itself, only a top view showing how to grind it to fit the ACME screw gauge. Anywone have a picture or diagram. One book I saw showed a "skewed" rectangle when looking at the tool from the front.
Any thoughts on material? I've got a lot of 12L14 laying around. This is a home shop not a business. Screw will be used for a cross slide vice.
