Thanks for a surprising number of helpful replies...somewhat unexpected for a niche topic. Apparently, I do have a Woodcraft in my city. Never would've even thought to look for something like that. Much like how I recently had another craft hobby come out of guns (holsters) and discovered that I actually have a leather craft store nearby, too.
Any, uh, by the way, anyone who thinks they're clever by pointing out the suggestive nature of some of the things in my first post...yeah...that's...the joke. I was aware.
I'd definitely like to get some nice maple to work with. I carved a set of grips out of a hardwood floor sample from Home Depot and they turned out rather excellent. Not that hard to work, sturdy, and after repeated oiling they are like glass. Just not that interesting, appearance-wise.
I'll head over to Woodcraft today and see what they have. Surely something. Still want to get some of those sweet, sweet burls off of eBay. I would love to get a big chunk of rosewood burl, which is unfortunately DAMNED expensive.
Here's some 1911 grips done with rosewood burl:
Goddamn magnificent, that stuff is.
