In June 2010, I gave a demonstration to the Montgomery County, Maryland, Woodturners (MCW) on the method of turning a dinner plate, platter, or small tray using double-face tape and a 6" faceplate on the lathe. They documented each step with photos and have posted the result with explanatory captions on picasaweb.google.com. MCW is an outstanding woodturning club and I strongly recommend them to you if you live in the Montgomery County area of Maryland.
