Nice work jim-I know what you are dealing with. Making those drive dog ears on the pad adds a lot of machine work. I spent a week+ making one pad perfect and that is why I made a mold and cast all of them. I'm sure you noticed the pitch changes as you transition from flat to the circle and that was the tricky part for me making the drive sprocket. Never got it exactly right. Looks like you have it figured out. Keep the pictures coming.

Tom,

Thanks, I thought I read a comment you made on another thread about the pitch, so I was aware of that going in. That would be a real issue if you didn't realize that and made a bunch of parts and THEN figure that one out!

Got a batch of pads mostly finished. Still putting the slot in middle that receives the drive dog part. And, I still need to drill the hinge holes. Going to be fun and should start to go faster once I get all the pads finished.
