Someone gave me a power tapping head for free, but I'm having a problem with the taps running out a lot (+/-0.025) in the chuck. I thought it was just a simple chuck... put the tap in and use wrench to tighten the nut and off you go.
The taps are held in a 3-jaw arrangement with locking collar to tighten. I cleaned these jaws and stoned to make sure no burrs were interfering and fixed one of the springs that had popped out of its hole in between the three jaws. In addition there is also a square drive screw above that when turned opens and closes an additional pair of round opposing 'jaws'. These 'jaws' have a half round cutout in the lower side that hits right on the square end of the taps. I tried tightening this down on the taps as well, but it didn't help at all.
I couldn't find a copy of a manual for this specific chucking setup so I could figure it out. Is anyone familiar with this particular unit and what I'm missing?
