For anyone interested in how the board was formed. the pictures of the jig tells most of the story.I sanded the tops one by one with an abrasive wheel. If I had to do it again I wouldn’t do any sanding til I had the whole board glued up. Even though I had the tops pretty smooth, after it was glued up, I still had to sand again to make sure the seams and corners were all flushed up. I made a couple of sanding discs out of a plywood disc and different grit paper which actually worked much better than the abrasive wheel…..

Precision is very critical with the square stock. I ripped down 8/4 boards and then ran them through the planer making sure they were all 1.73” square…..

The nylon ring is probably not totally necessary but I just happened to have it and thought it would make for smoother revolutions…...

The blade is 4 1/4”. Once I cut the base disc exactly to size, I glued blocks to keep stock from leaning. By spinning and slowly pushing down the stock, the pieces are cut. Only takes about 3 revolutions. They didn’t come out as smooth as I hoped but that’s what sandpaper is for…...

I turned the main pieces on a spindle 2 at a time, head to head. Turned the pawns 4 at a time.
