I know part of the fun is doing a lot of things yourself, but if you get tangled up in any of it and need some input or assistance, just let me know. I've got a brand new lathe and two mills in my shop at home, so I pretty much have it covered.
I may just do that. I have to figure out how and where to mount the single idler on a plate and affix the whole thing so it will have the correct arc of travel to engage the cam and crank gears equally. I can figure out the how and where, but I am sure I will need some help getting it made.
