I don't know on the Pam, I haven't tried it, it was an idea that just popped up while reading the post. It's vegetable based. I originally thought raw linseed oil, a wood lube I've used before, but would make an absolute mess of a jointer. With turned items any stray pam would probably end up in the chips, I'd test it first, but it sounds probable.
I've got a big block of sicamore (sp?) from my parents front yard I may get to cutting into call stock. If I do I'll put some up for swapping. It's the rough bark sicamore, not the white flaky bark stuff that grows well in northern California. It's got some sentimental value, I spent alot of my youth under the shade of this tree, and raking the giant leaves in the fall. Most of it unfortunately went into my Dad's neighbor's woodstove. I'd have liked to hauled more home, but they'd already given most of it away before I knew about it. That, and it was 270 miles away, I just happened to be down for a visit before the rest got away.
In the spring, if I get down south for turkey season, I'll throw my chainsaw in the truck and try to get some of those southern Oregon woods that don't grow here.
