The form is about 4" x 4 1/2". It's a cherry burl, and the pedestal is rosewood. I've included a quick picture with a pen in it for size reference. You may recognize the pen
This block was originally much taller, and was going to have a collar at the top. I ended up turning off most of the top to get to some solid material. It was interesting to turn, I've never turned a piece of burl bigger than a pen blank. You really never know what is inside these things. The large hole in the side was just a small 1/2" inclusion on the outside of the block. I thought it would turn off, apparently I was wrong. :biggrin:
I used a sorby midi hollower. It was an impulse buy at rockler, and wasn't the best choice, but it worked for this one. It's similar to the bottom tool on this page, but a little bigger and no thickness gauge.(

I've still got a good bit of practicing to do. The walls and base of this form are thicker than I would have liked. That hollowing tool is a bear. If your angle of approach is off even a tiny bit, it is going to let you know. My forearms were pretty tired by the time it was all said and done.
