Its hard to find large slabs of thin sandstone for my tables.  I had a pice that was almost 4 feet by 3 feet and took it to Denver to have the waterjet guy cut me a circle of 40 inches diametere.  The plan was to have half of the top one unbroken piece and the other half smaller ones.

Well the wagon wheel was not circular!   I had to break up the large slab and fit it in.

The rsult I believe is much better than I would have got if I had been able to follow my plans.

If you have a rim of a wagon wheel, I'd love to use it to make a table for you.
