Had some beautiful old fir, reclaimed bowling alley, full of nails, screws, angle iron, and tarred on the bottom, a real treat to work with. Cleaned it up, ripped all the boards to size, cut off the tar, cleaned my table saw with solvent, and the fence and my band saw and my hands, clamps, workbench, etc.
Made a countertop (bakers table or some such thing) for a dear friend. fit on her cabinet, 3 drawers underneath. glued the drawer slides to the underside (after it had sat in her house for weeks) all installed and feeling pretty proud. Over for dinner one evening a few weeks later and there's a quiet few minutes while we are eating, there is the loudest POP! It split from edge to edge straight across the middle. Its still there, I'm planning to do a stealth repair when she's away skiing next winter.
I always forget to factor in shrinkage.
