Been experimenting w/ resawing. I noticed that several pieces of oak (flat-sawn white) went great. They didn't move a bit after being sawed in half.
Then I tried some 1C alder and maple I had purchased (same source). The alder went okay but it moved quite a bit after getting resawed. In fact, it was bowed about 1/8" over a 36" board after the cut. After sitting in the shop for a day or two it was bowed in the OTHER direction by about the same amount!
I attributed that to higher moisture content on the inside of the board.
Then I was cutting some of the maple and it actually moved quite a bit while I was cutting it. It actually "popped" at the end of the cut. The last 1/8" or so actually didn't require sawing, the stress of the board popped it apart.
Is this typical for maple? Or do I have some maple w/ a lot of built-in stress? Or is this moisture related?
I don't have a moisture meter so I can't know for sure what the moisture content is.
