Or something like that.:rolleyes:
A post by Rob Cunningham a little over a month ago on turning a sphere gave me the impetus to try this piece. When I stopped by to see Robs homemade hollowing rig in October, we briefly talked about the David Ellsworth book that both of us had recently read. One of the topics was turning HF’s green to final thickness . When I left, Rob graciously gave me a piece of silver maple. It sat for a few weeks till I came up with something relevant to my visit to try with it.

I turned away a lot of beautiful silver/gray spalting swirls trying to get away from the checking that came in from the ends at the pith. Finally gave up after turning away most of the best color and still having cracks on the end.

I was going to take pictures along the way but the fear of expanding cracks and my slowness in hollowing made me forget about it. I ended up using CA on a couple of end cracks that began to grow while hollowing. Figured I would deal with the finishing consequences of that later.
I liked the whiteness of the wood in contrast to the gray but ended up using an oil so the CA stripes wouldn’t stand out as much.
I never arrived at anything close to a perfect sphere due to trying to rid the ends of cracks and not lose all the spalting on the sides. Don’t think I could have anyway even without those problems. I thought about cutting out a template to use that would have matched the diameter I was going to end up with but didn’t want to stop and take the time.

Finished with 4 coats of AO so far. 6.25 x 6.75 depending on direction. Opening is 1 1/8 after I mangled it, with a 3/16 wall or less. After measuring one spot at about 1/16 I got scared:D and left the bottom where the chuck was a little thicker. Ended up at 3/8. It has some flat spots but was fun to try. Thanks Rob for the pretty wood. Still thinking about building that hollowing rig!:)
Comments and suggestions are welcome!
