[QUOTE="JimGore, post: 75217, member: 3"] Progress update! Pics below: 1. Final horn profile machined out. 2. Two cuts showing the thickness of the flange, as well as where I will be parting the billet off. 3. This is as deep as my parting tool can safely go. There is about 45mm from the original 130mm left over there, so it is hacksaw time ;D 4. After drilling holes up to 15mm using standard twist drill bits, I get the boring head and boring bar out to go bigger. The boring head is actually made for machining on a mill, but with a change of arbor, I get it to fit inside the tailstock of the lathe. Lovely :) ...continued below... [/QUOTE]
