>Keith, I don't have a link handy, but you can use a faceplate and make a jam chuck to turn almost anything. I have been turning for quite a while, so I have a number of scroll chucks, but I still use jam chucks for different purposes. Screw a waste block to the faceplate, then glue another, deeper wasteblock onto it, and form the size jam chuck you need. You'll want to start your box blank between centers first, and form a tenon on both ends, just like you'd do for a scroll chuck, but with straight shoulders like a dowel. Leave some extra waste on each end to allow for parting off. Remount your jam chuck on the lathe, drill a hole in the wasteblock to just fit the tenon, and glue the blank in, making sure you have it aligned properly. Let the glue dry sufficiently, then part the bottom off the blank, leaving the top on the wasteblock, and hollow and finish the inside of the top, then part it off the wasteblock. Again, drill the wasteblock for the tenon of the box bottom, and do the same for the bottom. Finish the inside and outside of the bottom as much as possible, then part off the bottom, leaving a little extra for cleanup. Now cut a tenon on the wasteblock to fit the inside of the top, jam the top onto it, and finish the top of the box completely. Pull the top off, and do the same thing again for the bottom. Not quite as quick as using a chuck, but certainly simple enough. I always recommend to my students that they do an operation like this entirely using scrap wood, to familiarize themselves with the process, before using a nice chunk of wood. Check out Raffin's books and videos to see how he does it, and just substitute the jam chuck for the mechanical one.

Hope this works out for you, and best of luck. If you need further assistance, just email.

>This is the way I proceed with or without an expensive chuck. Turn the blank between centers and square off the end that is to be the bottom. Leave about 1/4 inch to allow for parting off. Also leave the marks to allow to find center on the top end. If using a faceplate and waste block turn a recess to accept the bottom of the box. Using the center mark left from the between center ruffing out secure the blank in the recess and glue in place. Now you are ready to start the box. Turn the recess that will be that part of the box top that will fit into the bottom. Turn a tenon on the top of the blank that is something smaller than this recess. Part the top from the bottom. Turn an opening in the box bottom that will accept the tenon on the box top. At this point the box bottom becomes the jam chuck for the top. Now you can hollow the top. Now reverse the top again and open the bottom to accept the top. At this point the bottom and top are in what will be the final position and you can shape the outside profile of both bottom and top together. Remove the top and finish the inside. Part the bottom from the waste block and sand the bottom. I'm never comfortable with my verbal explainations so I have attached a "crude" drawing that I hope will help. If not drop me an email and I will try to do better.
