Sorry Jim been gone for few days.
Sanding is the dilema. If you try to sand right away it clogs the sandpaper. You can unclog it by running it over a file card. This is like a wire brush that is used to clean stuck metal particles out of files. However as soon as you touch the wood they clog again.
What I do is to shear scrape as I go. This is done by tilting a scraper at about 45 degrees and pulling is along the work cutting with the lower 1/2 of the tool so you don't get a catch. This will remove much of the torn grain.
To get rid of really trouble areas stop the lathe and use a cabinet scraper. I use a flat one for outside and rounded one for inside the bowl.
I use a hair dryer to dry the surface of the wood. You have to be careful with this because you can cause checks. Actually I'll back up a little. First thing I do is blow all the water out that I can with a compressor. That speeds everything up. Then I use the hair dryer. I only dry it enough to let me sand. This can still be tricky. Try to dry the inside at the same time as the outside. This reduces the chance of checking.
The safest thing is to let it dry, warp, and then sand with the lathe off. However if you leave a big tenon on for the chuck you can have checks in the tenon that can spread. Sometimes I'll coat the tenon on the inside section of bowl over the tenon with Anchorseal end grain sealer and just put the bowl up for a week or so. Then I can remount it and sand with the lathe off.
The last thing I do is to turn the tenon off. If I turn it green from start to finish I dry it with the hairdryer and sand. Then I will turn the bowl around,place a rubber sink stopper over the chuck and pull the tailstock up to hold the bowl. Then I turn the bottom down to where there is a very small tenon left. I sand all of this are and then cut the tenon off with a small saw and carve away what's left.
