Dragline Rebuild

[modelman]

Jim-the pitch is good. The sides of the teeth on the main gear are not cut on the correct angle. I had no way to do that. I think that is causing the jerky motion since the pinion is not engaging smoothly as it rotates. The way this model is designed I cannot use a larger main gear. The one I have ordered is a 32-p-128T x 24T and I hope that will solve the problem. The swing gear-case is driving me nuts but I will keep working at it.
