Thanks guys. Kirk, yes the rings were a definite factor in deciding to back it before tillering. I've chased rings on some gnarly stuff but this one had very thin, wonky rings that I didn't trust myself not to mess up. So, I got it the best I could then checked the bends at floor tiller, which was easy thanks to the straightness. Then glued on the wet rawhide and proceeded from there. Probably not the ideal way to do things, but so far so good.
Oh, and brace on the unfinished pic was probably around 5" or so.
