Re: Offset Turning?

>In of of the Raffin books, I can't remember which, Richard has a simple way of doing offset box lids. He uses a four jar chuck with two of the jaws removed. A sacrificial piece of wood is held in the jaws, and a jam chuck turned in it. The piece can be offset and the piece rotated on the jam chuck to achieve offset designs. You could do this for small bowls, but would not do this for larger pieces.
I have the Escohleon (SP???) chuck, which has a faceplate adapter. You can use it on small bowls, but I don't think I'll ever use it on any large piece. It is really better suited for spindle work.
One of the English turners, name escapes me, made an offcenter chuck using two faceplates. One of the face plates mounts on the lathe and the other bolts to. The "swivel" faceplate has a male boss instead of a female coupling for your chuck. It also has a number of holes in an arch 180 degrees from a "fixed" hole. The facplates are bolted together in a singular hole and then the "swivel" faceplate is moved until the desired offset is achieved and the closest hole in the "arch" is lines up to a fixed hole on the other faceplate and bolted together. Cheaper than the Kelton, but it has no balancing either.
