Thanks, Les. I go back and forth on cracks. Some get thin CA, some get medium, some get thin epoxy with color. And some I say “well, I didn’t want that piece anyhow!” and let it become a lid or handle or pen blanks.
I’m not so worried about catches when hollowing. When I’m using a bowl gouge, I’ve got a pretty good feel for things now (and getting better with every catch), but I do the bulk of the wasting away with forstner bits and carbide tools. I’ve also made a few negative-rake scrapers with flat bottoms I can use inside a form if needed. All a matter of what the wood seems to need at the moment.
