I have a MiniMax T124 Italian made industrial lathe. Most of the stuff I use on it is Morse taper #2. I have a threaded Multi Star chuck and I remember when I ordered it it had a non-standard thread but it was a stock item. I was just about to order a PSI collet set in order to do blank drilling on the lathe and was figuring out the headstock threads - but I don't know how to find out for sure.
One online reference says the thread is M30x3.5 and I measure the exterior diameter at the top of the threads at 3cm. If so it wont take standard thread on stuff and that kind of sucks
