The Walnut platter I posted previously was the motivation for finishing this chuck. I had run out of options since my platter was too big to fit inside my Cole Jaws without the jaws hitting the bed, and it wouldn't work to expand inside the undercut rim for the same reason. And I'd already finished the inside. So what's a guy to do?
I designed a Longworth chuck in AutoCAD and cut it out on the CNC router at work.:D (I work in a nice cabinet shop.) Then I turned a faceplate block to fit the double step mortise in the back of the chuck plate, and glued and bolted it all together. There's a T-nut in the back of the faceplate hole holding the center bolt. It's loctited so it won't come out. It runs pretty true even though I didn't face off the main plate.
The stoppers were purchased at Lowes along with the other hardware which totaled about $10. The plywood and 1/4 melamine MDF was scrap. (There's lots of it when you install a kitchen a day.) I was wondering how to drill out the bottle stoppers but hit on a neat idea. Just push them into your spindle taper and drill from the tailstock end. Works like a charm!
