Like I said, I already have a 6-inch 4-jaw chuck threaded at 3/4-16. At one time, I snooped around on Ebay for such a chuck and, wonder-of-wonders, it's actually cheaper if you
buy one new from Sears.
Matt, you will have to verify the threads on yours with a caliper: the large diameter on the threads should be close to .750 inches, and you should be able to count either 8 threads in a half inch or 4 threads in a quarter inch. Something like that, anyway. If it's anywhere close to that, it should be good.
If that is the threading on yours and you want to get creative about chucking stuff up, you can buy a
tap on ebay for about $15 to thread things for 3/4-16. So you could theoretically make your own mounting plates, etc.
If you're only turning round stock, and your headstock has an #1 Morse taper, you can get
one of these little jewels. I have the exact same thing with a #2 Morse taper, and it works well for holding stock, provided you're using a live center at the other end.
I like a live center without a lot of shoulder on it, like
this one here. This one is for a #1 Morse taper, but they're available in other sizes, too.
And a person could mount a
cheap cross slide and fit in
some sort of cutting tool and use it for turning tenons.
But for me, it would never be worth the trouble of bolting and unbolting such a thing, as I can turn a tenon with chisels in less than a half an hour, including the time it takes to stop every few minutes and take measurements.
Unless I could use such a cross slide as a chisel rest, too, it would just be in my way all the time.
