You can never have too many clamps, but they can start to get in the way if you’re not careful.
Since I have a small car, it can be kind of tricky to get plywood home. As a result, I try not to use it unless I have to. I’ve seen a lot of folks make very nice plywood clamp racks, but I wanted to see if I could make something fast and cheap.
I ended up with a design that uses half a two-by-four ($2.50 each at the home store), a drill, and some kind of saw. I used a bandsaw, but you can make the cuts with a hand saw, a table saw, a jigsaw, or whatever you’ve got.
Here’s the gist: mark hole locations one inch away from the back. Space the holes every inch and a half. Drill them out with a 1/2″ bit. From the front, cut slots towards the holes at a 45-degree angle. If you feel fancy, use a roundover or chamfer bit in a router to clean up the edges.
You’re done. That’s it. Attach with screws. Enjoy.
