I've always wanted one of these bad boys and stumbled upon one up in the Northwoods this weekend. Had a reasonable price tag so I snarfed it up. Nice 12-inch radius with no real cracks. Made for a nice cocktail table while "camping". We guesstimated the tree to be in the mid-100 year old range (we found 10-15 rings per inch though bear in mind..this was over cocktails).
Anyway, does anyone know any background on the making of these? I'm not so much wondering about the mechanics, but more the wood stability. Are they turned green? Is the wood aged somehow? Aged after turning? I can't imagine why these things aren't cracked like an cold iron frying pan put on a hot stove.(but that's another northwoods story)
Just curious, I have the fixin's for a big arbor for a lathe and have always wanted to set it in a big block of concrete to mess around with large turnings. Do you think they were turned between centers or on a faceplate? the bottom has faint signs of a large 4 tanged drive spur of sometype.
so let me know if y'all know anything.
p.s. I'm not talking about the ones made of glued-up blanks, just real tree-trunks.
