The rolling mill at school lost a few teeth last semester. It turns out the handle gear has been wearing for quite some time. Check out the twist in that spur gear! I couple teeth just finally wore down and then cracked. I've been trying to get a reply from Durston for quite a while and they finally came back with an answer of "no replacement parts for this model". I decided I would press the gear out of the handle. There was originally a set screw that held the threaded gear into the handle. This set screw had sheared sometime during the life of the rolling mill and there was no way to unscrew the gear. I turned a mandrel on the lathe to press the gear and started heating up the handle so I could throw the whole thing on the hydraulic press. It pressed out easy regardless if the threads and then I was able to clean things up. I'm going to try and order a new gear which I will have to modify. The Durston is just too nice to not repair, so I hope I can nurse this tool back to life.
