Power drawbar on my Bridgeport clone mill

Nice work John. I'm going to copy it soon.

A good source for the linear shafts is used struts or shocks from a car/suv or whatever. I have been collecting them for years. The come in various diameters but i have some 16mm for this project.
 
Here's my take on the power drawbar. The impact is a CP the pneumatic push buttons are from princess auto

Oh looks good. You decided to make separate button controls for control of the impact, is that because the impact didn't have a butterfly style control?
