The Samurai Carpenter is a woodworker and trim carpenter out from Canada. He’s got a YouTube channel full of good stuff, shared with his own brazen humor. He knows his stuff, and you’ll see from the video below (and many others on his site) that he’s a very talented carpenter/woodworker. He’s even gone so far as to make his own customized work vest out of leather.

In the video below, Samurai Carpenter walks us through his technique for scribing and fitting a 1x10 around an odd-shaped beam. He could scribe the 1x10 to get a precise fit, but that would take a lot of time and wouldn’t account for seasonal movement of the beam or the 1x. Instead, he notches the beam with a multi-tool and chisel. He cuts the 1x10 close, then slides the board into the notch. One tip to this technique that he glosses over: he implies that he planed down the guide board to subtract the thickness of the multi-tool’s blade, which is a really good tip. You’ll see at the end that it would be nearly impossible to get a better joint. This technique is used a lot to run wood flooring under door jambs and casing legs. But this approach for fitting a 1x10 around an odd-shaped beam (or any beam, for that matter – because even square beams are rarely precisely square) takes that to the next level.
