I have just bought, (Finally!) a wee grinding wheel so I can now re-grind my lathe tools, as per grandad and Tubal Cain's way of doing it. Has anyone got experience, as myself, on the 'Ken Keeling's half-moon facing tool' ? The first thing I re-ground, and the facing surface, even though I am very rusty, is somewhat amazing! 10 degrees and half moon… ML7… Wow! Even I'm impressed!
