General | Manual Mill drawbar torque.
Ive got a bridgeport type mill, r8 spindle. Im in the process of designing and building a power drawbar using a butterfly impact, as done by many on youtube. My question is this. What torque should be made on the drawbar when tight? Does it vary with cutter size? Does a 1/4" endmill need the same torque as a r8 4" facemill?
