Topic tags/keywords: warped wood

Hi Everyone!

Today a friend of mine brought me a burning to frame. It’s 2ft by 2ft
in size, but the wood was severly warped.

Do any of you know of a way to flatten it out again? It’s birch
plywood 1/4 inch thick.

How do you all store your plywood to prevent warping. Thanks…Dannie

I can’t bend it enough to glue it to a thick piece of plywood. The bend is like a “smiley face’s” mouth

run some shallow saw cuts to the back of the pyrographed ply then you should be able to clamp it between two pieces of 3/4 inch ply gluing to the back bit

Depending on the thickness of the frame, you could sandwich it between 2 pieces of Lexan. Or a piece of lexan and a piece of plywood. I’d avoid regular Plexi though, it will fog over time.

spray water on the “cupped” side, continue to do so, on 4 hour intervals. In the interim clamp stickers to both ends and slowy apply pressure to flatten it out.

Once flat make sure all faces can breath

that is the way i flatten boards dannie. i wet the back of them then place them flat down and lay a bigger board over them and weight it down with heavy stuff. make sure if you weight it down tomake sure the pressure is over the whole board. not just part of it. and leave it until it is dry and f lat. at least 24 hours.
do not over wet it. that thin of plywood does not require a lot.

also when you frame it. leave a space between the board and glass if you put it under glass.

once flat. i would glue another plywood board to the bsack side. to give it some strength.

i do not burn on 1/8 in ply because it does warp.

Thanks everyone for your advice. Ok, I’ll spray water on the “cupped” side which is the backside of the burned picture…and I’ll put a bigger board over it….but I am leary of putting heavy weights on it…wouldn’t it make it crack? It’s warped so bad it looks like an archers bow. “Keep burning and learning”...Danette
