Is Your Square REALLY Square?


Hey Reader,

There’s nothing more frustrating than getting to the end of a project, trying to glue up a box or a drawer, and realizing the corners just won't seat right.

Usually, we blame our technique or the wood. But sometimes, the tool actually is the problem. Even a brand-new square from the hardware store can be off by a degree or two, and over a long cut, that adds up fast.

Here is a 30 second test to check yours: Grab a scrap piece of plywood with a straight factory edge. Draw a line using your square. Then, flip the square over so it faces the opposite direction and draw another line right next to the first one.

If the lines are perfectly parallel, you’re good to go. If they V-shape at all, your square is out of alignment.

It’s a simple check, but it’ll save you hours of sanding and "fixing" joints that should have been right the first time.

Now go build something awesome!

Videos | Plans | Tools Hey Reader, I think we all get a little bit of "analysis paralysis" when we’re about to cut into a nice piece of walnut or cherry. You’ve spent the money on good quality lumber, and you don't want to blow it on a simple mistake. The best way I’ve found to get past that is to test your setup on some scrap pine or plywood first. Once you’ve cut that joint or shaped that curve on a piece of scrap wood, you can be more confident everything will go right with the more...
