I am have a strange problem with a soft maple board I am trying to plane.
I started planing one side and when I was done the board had twisted about 1/16" or more.
I have had this happen with stress. Not a problem there.
I turned the board over and was going to plane some off of the other side.
I was tired so I loosed the vise and left it set for the night. Un-planed side up.
The next day the board had returned to almost as flat as when I had planed it the day before.
I turned the board back over to the side I had been planing on to flatten it a little.
As I was planing it I noticed the shims were getting loose again.
I loosened the vise and the board was bowed again.
I turned the board over again with the planed side down and left for another night.
Today the board is very flat again.
My bench is flat, I shim the board on the bottom so it will not rock.
My shop is heated and never gets below 60*.
I have used an 18" piece of this board a few weeks ago and never had a problem with that board.
Any ideas????
Thanks,
Dale
