 A simple jig every new woodworker should have. A circular saw guide rail. Hola, woodworkers, Paul Carlson here, a small workshop guy. You've gone to the hardware store, you've bought your 4x8 plywood, you're going to build a filing cabinet, a drawer or something, and you need to get that big piece of plywood cut down to where you can manage it on your table saws or your various power tools. So, you want to use your hand circular saw to get it cut down to approximate size. So, what can you do? Simply take maybe a 10-12 inch wide piece of plywood, half inch plywood, and cut a piece off that's about 3 or 4 inches, making sure you've got plenty of distance here that's more than the distance from the edge of your circular saw to the blade. I'll explain why in a minute. They glue the one piece onto the other piece. When that's dry and ready to be cut to size, you're simply going to put this on a secured area where it's all secured and flat and you can cut it, and you're then going to run your circular saw along the edge of this piece that you've made, and the blade obviously will be in exactly the right spot, and it will cut this off to the perfect length, which is the distance from the edge of your circular saw guide to your inside of your blade. Now you've got a guide that every time you want to cut a straight line, or cut a rough line maybe of sheet goods, you've got something designed specifically for that circular saw. If you have a different circular saw that's more powerful, that's corded, then do another one of these for that saw. And I find it to be very, very handy. What, 50 cents? Maybe a dollar? I don't know. Not much. Probably scrap wood that you would have thrown away anyway. So, world's simplest jig for your power circular saw so you could cut a straight line.
