I believe it has a #2M taper. The live center comes out easy by just backing the wheel all the way out. The headstock threads are 1" x 8tpi which is standard I believe. Thanks for the help guys. I am planning on buying this spur center. I will probably buy a chuck from here as well haven't figured out which yet. I was originally going to buy one of their lathes until I had this wonderful tool fall in my lap.

I am also going to buy the above mentioned chisels from Digger.
