Because it was shipped up here to Canada, they had to take most of the sapwood off before shipping it. Picture three is of the back or where the back will be once I chase it down to the ring I'll use. If you look at picture seven and eleven (the side views) you can see that I don't have a lot of room to work. With that being said after looking at picture four, how many rings would most of you go down? Are most of those top rings too thin or would you guys just go down two or three rings and make that the back? By the way, it is 72" long and will be unbacked. Also if you look at picures one and two, these are obvious pin knots and I'll have to leave them raised when establishing the back. When you look at pictures five, six, nine and twelve (I hope this doesn't make me sound stupid) do those look like knots or is just old wood left on there? Should I leave these spots raised or work through them when chasing rings? I appreciate all the help from anyone willing to give it. I'm excited about this project.
