Dragline Rebuild

This segment is lesson #1 in what NOT TO DO!!! I had some small sprockets and I decided to make my own swing gear to match the pitch. I had to make it in-4- pcs. because at the time I didn't have a pcs. of alum. that big. After a lot of machining I got it to work but it is a bit "jerky". and not smooth at all. So now I have ordered the proper gear and pinion and while I am waiting I can work on the swing gear-case. Lesson learned-

Still very interesting to look at! What exactly do you think made it not smooth? Pitch not perfectly matched? Not enough teeth?

Very nice looking, keep the updates coming!
