I am glad you are back working on this Rusty.
I have a friend who has run a gear drive, I will bounce it off him and see what he thinks.
I had been thinking about cam walk, were cam profiles supposed to keep the cam back?
I know Will with the 68 Turbo Barracuda had to run a thin roller bearing behind his top gear.
His cam was walking backward.
I have the thin torrington bearing. It came with the gear drive kit. I plan on utilizing it. I've just left it out as I mock things up. Thanks for that. I'd like his input as well.
