I am trying to find a way to hold a small leg for a breakfast tray while you eat in bed. The legs are 8.5" long and 1.125" square with a 1.250" long mortise in the leg. Right now I am using a Nova G3 chuck with the spigot jaws. It barely opens enough to hold the leg. The problem I am having with this method is the jaws are making marks on the leg. I can't use a screw because of the mortise. It's Christmas and I am between a rock and a hard place. Here is the lathe I am using.
