At the AAW symposium this year I was introduced to a negative rake scraper. They do a great job of removing tearout. Use it after the bowl is turned to shape and before sanding to virtually eliminate tearout.

Have you tried power sanding on the lathe? What tools are you using? What species of wood? Green, air dried, or kiln dried?

When I am doing my final cuts in the inside of the bowl I sharpen every pass. After seeing this at the AAW a few years back with Glenn Lucas I get very little tearout now.

It is dry cherry that was turned wet 2 yrs ago I just rechucked it and am finishing the outside first. Using a 3/8 fingernail grind bowl gouge. I tried a scraper but made it worse. Thanks for replies. Joe

I apply sanding sealer and let it dry before my final passes. Very sharp tool, hone between passes for a couple of times and then resharpen. Try to make a complete sweep and not break up pass a lot.

Also make sure you are cutting in the direction that supports the grain. From Bottom to rim on the outside and rim to bottom on the inside (for a normal bowl shape).

Haven't had a lot of trouble with cherry, but hickory gets the 80 grit gouge.
Ditto on the sharp tools.

One other suggestion is to wet sand with shellac. I'd go with Zinsser's SealCoat wax free to avoid possible finish compatibility issues.

Sharp tools is the best way to prevent it. Like mentioned earlier. Use a sharp as possible tool on you final cut. But obviously the better cut you have the less sanding you need to do.

Anyone try an Oland tool? I've just finished one, waiting on it to dry to try it out.
