I scored some 2' wide old-growth clear white pine that's now dry and stable. Planks are between 10/4 and 12/4. I'd like to resaw it to 4/4 for a batch of sea chests. It's too wide for my bandsaw, local sawmill won't/can't deal with it, and I haven't found anyone local (Cape Cod) with a portable bandsaw mill. I'm tempted to get a Roubo frame saw and have at it. I'd guess it's between 100 and 150 lineal feet of sawing, so it seems like a handful for a handsaw, but I'm game to try. I've also thought about ripping in half (width-wise) and then gluing back up, but that seems like a less preferable option.
Before buying a frame handsaw, I'd appreciate any comments from folks who dealt with this.
