Topic tags/keywords: unstable shrinkage swelling cocobolo cherry

I’ve made some pieces out of Cherry, the pieces keep moving. Farm table and pub table. On the farm I put a small bread board on each end. A year later I’ve had to trim the bread board just to have it two weeks later be to small. What gives?

I am not sure exactly what you mean about moving and getting too small. Can you take some picture of them?
If you glued the breadboard, that could have been the cause. If the tabletops buck and or split, it is more likely that they weren’t installed so the top could expand and shrink freely.

Your description sounds like wood expansion/contraction die to moisture content. Was it kiln dried?

Check out the shrinkulator to get an idea of what movement to expect.

Breadboards are great. But they are only the “right” size twice a year when the humidity is the same as when the piece was made. The table will expand and contract forever, while the breadboard will never get longer or shorter, leaving the table too wide or too narrow for the breadboard most of the time.

When wood expands and contracts and does it more across the width than it does on the length.
So your bread board ends, the length, won’t expand at the same rate as the width of all the planks.

That’s how Cherry is. Is the table still beautiful and usable.

Seinfeld fans would tell you to ask George Costanza about shrinkage. He is an expert.

Here’s a whole page of articles and videos on how/why this is happening to your table.
