I own an X2.

Is the column on the Taig the same style as a X2?

I want to know if this will fit:

Shouldn't be, they are different animals.

I don't think it will fit. If you want a high speed spindle option for your X2 you could try this:

I actually have a Taig and a Wolfgang spindle but I don't have the dovetail mount. I was just going to attach the spindle to the side of the Taig spindle mount.
