I came across a nice sized burl in a tree that had come down. Unfortunately, there was a chain sticking out of it. But I didn’t want to pass up the burl. I figured, “No problem. I’ll just unscrew the anchor and still get a nice sized bowl.” While attempting this I broke anchor (or what I thought was the anchor) at the wood’s surface.
So I mounted the piece on my lathe anyway and started to turn. My intent was to carefully remove enough wood around the metal so that I could get a purchase on it and twist it out. I was fairly successful at removing the wood. However I quickly discovered that the “anchor” ran deeper than I thought. I took the wood off the lathe and started at it with a chisel.
After about a half hour of work, my growing suspicion proved correct – the “anchor” was actually part of the chain, which extended into the wood about 3”, and formed a loop arond the center. Someone must have put the chain on this part of the tree when it was less than 6” in diameter, and forgot about it. I’m guessing that the growth of the tree around the chain gave rise to the burl. I did manage to save some of the wood and I hope to post a turning.
Pic shows where I dug in to the wood (starting from the bottom of the pic, and moving left)
Pic shows cross section, where two severed ends of the embeded chain (dark grey marks, left & right) are exposed.
And as a bonus I was able to recover some antique chain parts!
So be forewarned: If you ever see a chain sticking out of a burl…
