Want to know more about making a Rose lathe pump?

[Curt George]

Hello everyone. I have been doing some research on the Rose lathe. The pumping element has me wondering.
How do you control the slop IN THE MOVEMENT? and how strong of a spring is needed to control the pumping back and forth?
Any help would be Appreciated.

Thank you. I have not seen this before.
I did not know that there was a second version of the MDF lathe.

Curt, look at the red books on the 2nd shelf in the MDF Rose Engine 2.0 Library. The 1st one (volume 1) outlines a pumping mechanism.
