After wrestling with the lever drawbar and suffering some rubbing and occasional drawbar backing out due to the rubbing I decided to reinvent the wheel and make a new power drawbar.

Here is the CAD file if anyone is interested. A360

One thing to note is that my cylinder is an MP4 2 stage, which only has about 2400lb of force at 100psi. I would recommend anyone doing this use the Fabco MP4 3 stage to get about 3600lb of force at 100psi.
It's the same footprint in the cad file btw.

My belleville stack is set up for 2100lbs right now. Once I upgrade my cylinder I will change the stack to a 3200lb stack. This should be fine for most operations.

Here is a mcmaster parts list for the small parts I used. I had a bunch of 1018 3/8" steel laying around for the bases and 1/4" for the uprights, just TIG welded together.
