I always say, "I love a good laugh, especially when it's on me." Here's my latest "duh moment." I spent a long time with a combination plane hand-rabbeting some pine boards for building a steam box. (Note: I do this by hand because I enjoy it and not for bravado.) All I had to do was drill the holes for the dowels that will hold the items being steamed suspended so heat can get all around them. In order to make the holes match up on either side, I clamped the two boards together, and drilled all the holes through both boards at the same time. Yes sir, I'm smart like that. So smart. I'm so proud of how smart I am...

...and then I went to assemble the thing. Turns out I clamped the boards together both facing one way, when the rabbets should have been facing inwards, so one board is okay, but the other doesn't match when you put it the correct way. UGH!!! SO- this morning I made another board, and tonight I'll clamp it to the other board the RIGHT way, and match the holes up.

So- what stupid thing have you folks done lately?
