The main reason I ended up with my design, was it was the best way I could find to fit everything into the available space, plus I was aiming for a pretty large ratio, so pulley size wasn't really an issue. Everything was made from hot rolled steel, due to it having to carry the full weight of the knee.


That was my 3rd revision of the design. Prior ones used two single row angular contact bearings, but they were too tall to fit in the available space.
Once I get the Conect lathe up and running, and get the Triumph manouvered into place, I'm hoping to get back to the milling machine.

If you want the actual solidworks files, PM me your email, and I'll send them over.
