I asked this question on top of another post but I figure it may be easier to just post it separately. I was charring a pine table top last night and to my dismay, I found that when I was done that the sides had warped upwards. I imagine this is from the heat of the torch shrinking the fibers on that side of the table, but now it wont lay flat without being clamped to my workbench. Is there a way to make it sit flat again? Maybe charring the underside?
