Flattening a wooden potato chip question

Barry Irby

My son brought a burl back from Florida maybe fifteen years ago and we had it sawed into slabs. Some of them are about 24" by 30" but sadly only 1" thick. We did not know to saw them thicker. Now we would like to make a coffee table out of one. Don't know what the wood is but it's not something we would find here in VA and tough as nails.

If we try to flatten this potato chip on a CNC we will end up with nothing. Been thinking of steaming it and then weighting it down, making it flatter and drying it again. Any suggestions?

Finish it as is and display it under a glass top that floats above. Make lemonade out of a lemon.

First get your fixturing ready. Two pieces slightly larger then the piece you are flattening. I've used quals, about 4", made from particle board. TYop surface, bottom surface and spacer pieces. Then steam the piece to be flattened and put it between the 2 quals. Let it sit for at least several weeks as the moisture in the wood will be absorbed by the qual surface and eventually evaporate.

That is a good idea...

One could either cut down til the get 3 flat coplanar spots and use little rubber pads at those spots for the glass, or make decorative standoffs that attach to the glass. I'm a sucker for drilling holes in glass for some reason - the first method is far easier :D

A table only has to look like it's flat;

on one side ;)

Flatten the edges of the concave side the put nuts in the middle dish. ..Or cover with glass with some decoration in the middle, such as your childhood set of jacks or marbles or coins. ..Or put a lamp in the middle. ..Or do all at various times . . . ..Or fill with decorative epoxy or a contrasting wood.

As a famous person (Clint Searl) said : "When you've got a lemon, make lemonade.

If it wasn't kiln-dried, it should be relatively easy to manipulate. Maybe just rehydrate it by soaking in water for a week or so. If it straightens out, clamp it flat and re-dry. If not, go for the steam; you'll just have to build one heck of a steam box.

Do we really think it is possible force wood to be flat with weight, heat and moisture? If so how thick a piece can you impose your will upon?

Seems to me it turned in to a potato chip because it was thin enough to bend if it was thicker it would have cracked to relive the stresses. The parts of the wood farther from the pith have to shrink more than the wood closer to the pith this tension had to be relieved by the wood moving vertically as yours did or the wood has to crack.

Part if what I find interesting about wood is that that it is a living thing and every piece is different from the next.

How thick?

Dave Bair

He stated his pieces are 1" thick.

would it be possible to saw it up into pieces (like pizza slices or otherwise) that can be flattened, and then edge jointed back to a flat table top? this way you would loose minimal thickness, especially if you dont flatten the bottom.

And if it can´t be done, maybe cut up into knife handle blanks?
