Are all C&P OS Presses treadle-ready?

So, in the wake of our loss of one press, we’ve found ourselves in the position to possibly purchase another. It’s an OS C&P 8x12, but I haven’t gotten a clear answer as to whether or not we can use a treadle with it. Currently, it has a motor, and the photos I’ve seen have not specifically been of the crank shaft, so I can’t see from the photos whether or not I can remove the motor and use a treadle instead.

This is kind of a “duh” question, I’m sure, but I thought I’d go ahead and ask anyway since I know the answer will be helpful:

Do all OS C&Ps have the u-dip in the crankshaft?

No, they do not necessarily have the “U” dip. However, you may be able to switch crankshafts for one that does, if you can find someone who is parting out a broken press

Bill is right… not all C&Ps had the crankshaft.

Just as a clarification on terminology: a crankshaft is the technical term for that shaft with the ‘u’ crank in the middle. This is the shaft that would receive a treadle. The straight shaft is the one that would not receive a treadle. C&P uses these terms pretty specifically in their literature, so if you’re looking for parts be sure to ask for a ‘crankshaft’.

Hope this helps,

Thanks! That helps a lot. :)

Terminology . Crankshaft is bastardized usage of the term Cranked Shaft .
