My rotary table is a Phase II 10" and should have a MT3 bore....but it doesn't. It's a short 25mm straight bore, only about 20mm deep. I have no room for, nor any desire to get a shaper. Yes, I know what they can do and have run them before. I just can justify getting one in the small shop I have just because it can do a couple of little things I can't easily do on my turret mill.
It occurred to me that I don't have to broach it. It's a "low force, low speed" gear, so I'm just going to lay it flat on my milling machine and make a "horseshoe shaped" keyway. Simple.
