Preparations for gear cutting
Almost ready to cut the lathe gear. It is 237mm diameter, 25mm thick, with a new rim Loctited and Scotch pinned to the old hub.
And today I made a tool holder for the new-old gear cutter which I purchased from Russia. It was meant to have a 27mm bore, but when measured was closer to 27.1mm, so I made an arbor to match.
Meanwhile, on advice from Swen, another GSMEE member, thinking ahead, and setting up to trial fit the new gear after it is cut. Here is Swen, making some steel temporary bearings to try the new gear on the shaft, after the gear is made. Tapping out the old taper bearing races. This is what Swen did for a living when he was in the work force. I have learned heaps just watching Swen doing his stuff.
