Having picked up a "new to me" lathe, with a 1 1/4x8 thread on the headstock, as opposed to the 1x8 on my old one, I went looking for a new chuck. I got a headstock spindle adapter from PennState (would you be 1-2 thou runout?), but wanted a chuck I could use without the adapter.
I looked at a lot of sites (finding Ebay more expensive than Amazon) and finally looked at Southern Tool. They are having a special on the SuperNova2..
