Wonder if you could use a set of wedges like those used to remove drill press chucks to remove the drive center ? http://www.jacobschuck.com/accessori...ed-on-3jt.html They come in different sizes and have no idea what size if any would work for mt2 but maybe your machine shop guy could help. I have an old babbitt bearing headstock which also has a taper in the inboard side of the spindle but is not drilled through for a knock out bar. I have no idea who made the head stock I have as it only has some casting numbers on it and have not seen another like it. If companies were doing this then there had to be a way of removing drive centers.
I know the voices in my head aren't real but boy do they come up with some good ideas !
