I am nearing the end of a birdseye and walnut jewelry box (mitered corners all around with an open front for drawers) and I wanted to get a head start on finishing the carcass as I was building the drawers. Well, I applied the finish and set the pieces aside to dry.

I guess the sun was perfectly aligned, heated the pieces and the top and bottom are slightly twisted. The back is severely twisted. Any way to correct with clamp pressure? As all the joints are miters, I can’t just plane it out as that changes all of the dimensions.

Any ideas? Can I put the pieces under clamp pressure and hope they come back? Could I sandwich them between two boards and put them in an oven? Anything?

Thanks.

Jeff

You could try it in the microwave for a few seconds till slightly warm not cooked LOL then apply pressure with a few clamps and leave to harden-cool but I would advise you to practice this first on some bent scrap so I am not accused of ruining your lovely box..I have actually heard of this working Alistair

Thanks Alistair. I’ll give it a try. Maybe a wet towel in the microwave then clamp it to the table saw top?

You clamp a piece of damp wood to the TS top and you’re gonna have another problem called rust.

good luck. I think your toast. But I have had success flipping the piece over and putting it on wet grass in the sun. A combination of the sun on the opposite side and the dampness may bring it back. I’m not sure how often I’ve used this technique, but if I had to pull a number out of my a%$, I’d say it works about 25% of the time.

Watch it. There is nothing more frustrating than finding out it had worked but you over did it.

Well it is cooling now. 5 minutes w/a damp rag and now clamped down. This is for a graduation party Saturday! I don’t think I could get a finish dried by then…

I’m going to leave it clamped for an hour or so. If it works great and if not it’s to the jointer and planer…arg.

Lesson learned!

Shellac would be dry by then and more than durable enough for a jewelry box

Lacquer also would be quick

Thanks Doc. I have used shellac in the past but can’t remember if I cut it…this finish was going to be tung oil then maybe an arm-r-seal top coat.
