Hydraulic Power Drawbar (PD) For Round Column Mill
One issue regarding the air impact is that my mill, like a lot of them, requires a tap on the drawbar to get the collet to "let go". The problem with the "Wrong Fu" round column type of mill is there is no convenient "shelf" above the spindle and quill to mount PDB components, just a large stepped sheave and then the folding belt guard above that.

DIY Power Drawbar for my Bridgeport
Food for thought. One thing you may not be noticing about other power draw bars is that they actually help break the taper on the collet loose and eject the tool. My Kurt draw bar does this by stopping the drawbar from rising up and in return forcing the tool out. Here is a pic of the actual drawbar supplied by Kurt.

Re: Drawbar - Belleville Stack selection. 1. Figure out your desired clamping force. (>2200lbs) 2. Figure out your minimum travel to release the TTS. I figured on .125" when I built my PDB, but really you only need about .040" unless the TTS shank or collet are super-cruddy. Go with .050" or .075" to be safe. 3.

Power Drawbar Issue/Question
I had a 30 taper quill machine (yes, cnc) with an air powered drawbar. Had a Kurt setup, using a 3/8" air impact to drive the drawbar. To fix when things needed adjustment, I just removed the cover of the assembly, disconnected air, removed maybe 4 cap screws, then lifted the assembly off the top of the head. Then the drawbar lifted out.
