I assume that once this has been done the first time that removing the bell housing to replace clutch etc. will be centered the next time it is put back on the engine.

Ron,
I can see you edited your post a little and I hit the reply button in the interim. No problem! Keep the questions coming.
We actually used a mill, but a drill press (or even by hand) would be fine as they do not need to be too accruate.
Yes, you must weld the dowel pin bushings AFTER the final centering. It can get very tricky as the bell housing will move around while you are tightening it. It can really try your patience. Yes, the bell housing will stay aligned forever...well, at least until someone line bores the crank journals which is what screws up the alignment in the first place--especially watch out for original blocks.
