So I’ve got a problem. I bought an ash board from Rockler last week. When I got it in the store it was nice and straight. A few days in my shop (a drafty, unheated barn with a dirt floor) the board cupped quite a bit. The board isn’t wide enough for my project so I have to edge join two pieces to make a wider piece. But of course the warp in the board means the glue joint isn’t straight.
The wood is only 1/2 inch thick. If I run it over the jointer I’m going to lose a lot of wood and I’ll be left with something the thickness of a toothpick.
I tried sticking the pieces in a vise for a day to see if that would help and it didn’t. This is basically happening with almost every board I bring into the shop.
I realize the environmental conditions in my shop are terrible. But I can’t do anything about that. It’s too large and drafty to heat or dehumidify. I’d be trying to heat and dehumidify the outdoors.
I’ve run a few pine boards over the jointer that were warped. I put those things into a vise for a month. It didn’t straighten them at all. After removing about half the wood it was (more or less) straight. But it wasted a lot of material. And, of course, in a day the newly flattened board warped again. Plus, lumber is expensive and half of what I buy turns into jointer shavings.
Is there anything I can do to:
1.) Prevent the warping when I bring a board in.
2.) Straighten the board out without losing so much material.
I suspect the answer to these questions is: No, not with my current location and equipment. But I figured it couldn’t hurt to ask for ideas.
