Mounting an AXA QCTP on a 9x20 lathe

[Crusty]

FWIW - when I make a press fit that doesn't turn out as tight as I want it I'll often knurl the end of the shaft to make it a little bit bigger in diameter to tighten up the fit. Traditionally straight knurls were used for this purpose but diamond knurls work too and along with a little red Loctite the pins will be solidly in there.

I agree that there's problems associated with using those mag bases but the most significant one for me was that there wasn't a surface anywhere useful for me to put one so that prompted the ways clamp base design. I moved the arm to the other side of the clamp and that proved to be more useful, and then it dawned on me that I could mount another arm on the other side with a 2" indicator and have a range of possibilities all in the same footprint. I'll mount it today and see if it's going to work out or just be mostly in the way.

I thought a bit more about your problem of the dog slipping on the mandrel and wondered if perhaps your mandrels don't have a flat at the end for the set screw to tighten against. If not you should put a flat on the mandrel to tighten against and then that slipping problem will be a bad memory.

I first heard AVE on Youtube refer to a hammer as a swing press and got a chuckle out of it so that's what I call them now.

I've become a fan of VX belts. They fit onto the same pulleys as V profile belts but they have more grip strength.
