Amazing Circular Saw Jig: Quick, Accurate & Easy

How to make an accurate and easy to use circular saw jig for cross cutting or ripping.

Yes, this jig has been around for many years and you'll be surprised at how simple it is to build. I have several in my shop and I use them for cutting plywood, and door bottoms, and more. No woodworker or carpenter should be without one.


  1. EXCELLENT !! 😉

  2. So simple, so clever! Thanks

  3. thanks for the vid. easy and very useful

  4. Simple and effective, thanks for the great idea.

  5. I’ve made a number of these jigs for different saws. I do it exactly the way you do. I use 1/4″ ply for the base. Remember folks to lay your jig on the “save” side of the cut, if you lay it on the scrap side, your piece will be a kerf width short. Great video.

  6. Great video, so simple when you know how.  By the way, has anybody ever said you sound like Joe Pesci the actor!!

  7. Very cool stuff thanks bud.

  8. Very useful. Thank you for sharing your knowledge. I will make one tomorrow to cut my kitchen worktops.

  9. Made my jig the day after I saw this video and would be lost without it! Many thanks!

  10. Smart! Thanks so much 👍

  11. Awesome idea. So simple. Thanks for posting

  12. Thank you. Great idea! Since I’m a beginner, I really wish you had shown the smaller side. But I got the idea. Thank You. Just subscribed after watching this simple yet elegant technique.

  13. I especially liked the explanation!

  14. Excellent tutorial. Thanks!

  15. Folks: Don’t assume that your guide wood on top of the jig is straight. I’ve bought warped wood that was only apparent after fitting it where it didn’t fit because of a slight curve.

  16. Simple, but perfect!! Thank you. I’m of to make 4ft & 8ft.

  17. Why do you need both sides? Won’t cutting on the short side make the saw unstable and not stay 90degrees?

  18. If you’re just cutting plywood in your shop, you may not need the shorter side. If you use the jig out in the field, though, sometimes the shorter side is needed just for physical access when things are tight or when you can only cut in one direction. It’s just an option to have if you need it.

  19. Great Video. Friend suggested this jig and you pointed out a few things I hadn’t thought of probably saved me a bunch of time. Thank you!

  20. Do you think this will work to joint 2x4s and 2x6s? I’m trying to find a way to joint accurately with a circular saw.

  21. You don’t mention what you are trying to do with the 2x material–is it crosscutting? Ripping? This jig will work with any style of wood as long as you can fin a place to clamp it down and the saw blade depth is adequate to get through the thickness.

  22. Ah, yes. Good point. I’m talking about ripping the 2x for a tabletop. I don’t have a jointer nor do I want one. I would like to joint these edges as close as possible. I’m fine doing touchups with a hand plane if necessary. It seems like this jig would work perfectly as long as the jig is perfectly straight, the saw is tuned, and the clamping is sound. I keep reading that it is impossible to joint without a jointer or a masterful hand and a #7 plane. I’m new to all of this and would love to live without a jointer.

  23. I see. Well, you could rip with the jig as long as you figure out a way to clamp it and stabilize it on the workpiece. You might even cut the 2x material longer than you need for your tabletop and then screw the jig right onto the workpiece so it can’t go anywhere, then cut the ends off the workpiece after you’ve ripped. As for the jointer problem, you can definitely get straight clean edges with hand planes if you have the right plane. There are lots of old hand planes for sale at flea markets, auctions, online, etc. I have antique wooden planes that work as well as the day they were made. A longer plane will give you the straightest edge. You’ll want to cut the workpiece a sixteenth to an eighth wider than you need to give yourself material to remove with the plane. Remember that there is direction to the grain, so one direction will be easier and smoother to plane than the other. If you get chip-out, switch direction. Like anything, with practice you’ll get better.

    how do cut in 45

  25. You can cut any angle with this jig–just mark the line you want to cut and place the jig on it. Use a square or an angle finder to mark the angle you want to cut.

  26. This is so helpful. Thank you so much. I appreciate your wisdom and your time.
