   SODD -

   Nova makes perhaps the least expensive scroll chuck that I've run across. Check Rockler or Woodcraft, among other on line catalogues for what they carry. OneWay is another but more expensive option. I chose the OneWay because it seemed a bit better from the perspective of the machining of the various parts, the options available and so forth.

   I'm not familiar enough with the Nova line to offer any suggestions. Depending on the size of your lathe, the OneWay Talon chuck is sized for smaller lathes, the Strong Hold chuck requires a pretty hefty machine.

   When I win the lottery, I plan on buying a VicMark scroll chuck for no other reason than I want something as beautiful as that on my tool shelf next to the lathe! (grin) They really *are* nicely done .... but correspondingly expensive.

   With One Way chucks you purchase an adapter that fits in the back of the chuck to adapt it to the threads of your spindle. Not sure about Nova or others, you probably have to specify your spindle thread size in any event.

   Most scroll chucks operate in much the same way one to the other. What you want to be cognizant of is the method used to open and close the jaws. Some use a single key that resembles a huge drill chuck key, some use levers, perhaps there are still others. What I like about the OneWay single key system is that it's a one handed operation to open and close the jaws. Other mfr's make 'em that way, too, of course but what I'd suggest is getting one that can be operated single handedly. Consider holding a big heavy bowl blank of green wood up to the lathe trying to mount it in the chuck and having to use two hands to close the chuck jaws.

   Make sure whatever brand chuck you get has available a broad range of changeable jaws. This is pretty much the case these days anyway, but check out the options first. Don't overdo it with respect to your lathe; get something suitable for its size.

   Does this address your question with regard to "...and explanation of why to use one over another."?

   You can do anything with a faceplate that you can do with a chuck. A chuck can be more convenient; a faceplate is usually more secure. I've used a lot of different brands of chucks. The jaw profile of the Oneway gives it more gription.

   Faceplates were all we had before jawed chucks were available for wood lathes. Before faceplates, bowls were turned between centers. It just depends on what level of technology you want to spend your $ on.Clay Foster

   I have 1000+ bowls plus lots of boxes, pepper mills, etc on an original Nova scroll chuck, needless to say, I'm a believer.
