oh, that's a liggie; even visually almost an identical match to a block i got years back for conversion to a maul. beautiful, beautiful stuff. good samples have a wonderful perfume and exude a filmy wax. scrape off, and in a few months it comes back. that oily wax is one reason why (i recall) they once made ball bearings out of it for early industrial use (steamers, even early submarines). it could take the abuse and the oily wax self-lubricated, so you didn't have to worry about adding grease.
yours is almost certainly one of the lesser varieties. i think the original species was banned / became commercially defunct as far back as the early 20th century. super high demand, slow growth, restricted home area. some legit supply might still be entering the market, but not something you're likely to find in a bargain bin in Joe's Hardware shack ... and certainly not for bargain prices.
that said ... they used this stuff for ball bearings and hard-use tools.
worth repeating: it was used for BALL BEARINGS and hard-use tools, stuff normally made of iron or steel blends.
density will be a working issue, but that oily wax is the bigger long-term problem. (use a scraper to remove; only sandpaper afterwards.) this stuff can bleed oily wax for years; mine's still going at six. best bet is to use physics and design to your advantage and avoid adhesive-based solutions entirely.
brilliant when used for the right purpose; nightmare if you try to make it into something it's not. t'ain't oak, t'ain't pine, and it t'ain't maple 'er cherry neither.
