Aspen Un-Bowl Part Deux

I pulled the clamps off of the Aspen glue-up this morning, drew corner to corner lines to find the center on each end, then using a compass I made the biggest circle that would fit, about 7-5/6" diameter.

Next, I used a drafting circle template to draw a 3" circle in the middle of one end, this is where I will glue the sacrificial wood face plate which will be 3" in dia x 1-1/2" wide. I use TiteBond Original (Red) wood glue.

The sacrificial pine wood face plate is what I will screw the steel face plate to for mounting to the lathe.

I do this so there will be no screw holes in the bottom of the bowl. When the bowl has been carved, sanded and finished I will then reverse it on the lathe using the larger jaws on the chuck and carve the sacrificial face plate off and sand and finish the bottom. I'll post a picture or 3 of this process.

To the left of the glue up above you can see the 4 jaw chuck for my lathe. The black metal object just to the left of the green paint jar. It's a Penn State model, nothing fancy, that uses 2 Tommy bars for tightening and loosening. As it sits currently it has the 3" interchangeable jaws installed on it. I have various other jaws and holding nubs for it and use it extensively. Because I do use it so much I really need to get a 2nd one.
