To keep the streak going I finished the clutch cap on the lathe today. The first milling operation went smoothly but this lathe operation had a slight bump or two in my way. I initially programmed the part using conventional tooling but the recessed pocket really needed some more specialized face turning cutting inserts. The problem was minor and did not cause any undue headaches but the program needed to be redone.
The first step was to cut some profiled soft jaws to hold the part:
The small burrs you see are away from the profile and will not cause any clamping problems.
Unfortunately I was on such a roll I machined all 3 parts without taking any pictures of the process! Here’s the final 3 pieces looking really good:
The clutch side is nearly complete and looking great. I’ll try to get to the oil fill and crank end plugs today then next week I have to do a bunch of contract machining so will likely be too busy to make bike parts. Damn. I will try to get to something done to keep the streak going.
