Re: Applewood bowl

Now we're starting to get into the good stuff. Gotta get to the beauty pics before Hobbyman burns up his whole apple tree!
As it happens, this is the very same bowl that motivated me to design and build the Cole-jaw extenders that I wrote about back in March, in this thread. After the bowl dried, it was severely out of round. The rim of the bowl was out by a good 1/2", and even the round tenon had turned into an oval that I didn't trust my chuck to hold securely. So in order to finish-turn it, I had to get creative with the workholding. If you haven't seen that other thread, here's a pic of the jaw extenders that I made using the WoodAnchor fixturing system.
And here's what the rough-turned bowl looks like when it's spinning. The ghosting at the rim and at the the tenon periphery show just how out of round the bowl is.
This picture, taken after finish-turning the bowl bottom, shows it even better. Check out how much the thickness of the unturned rim varies.
Now, with the tenon trued up, I can flip the bowl around and chuck up on the tenon. The pic below was taken after finish-turning the inside of the bowl, refining the bottom curves a bit, and applying a few coats of satin wipe-on poly. Instead of just putting a flat on the bottom of a roundish bowl bottom, I decided to leave a small "pedestal" for visual interest.
Now it's time to get rid of the tenon. So back into the cole-jaw extenders it goes. When I see turners removing tenons from large bowls on YouTube videos, they usually cut it off with a hand saw, and then flatten and smooth the bowl base with a sander. But the Cole-jaw extenders enabled me to simply turn it off, which is a much nicer process.

In the next installment, we'll cover a couple more nifty details, and get this bowl ready for Christmas morning!
