I’ve seen a lot of people asking about how to get a straight line on a board without a jointer. I don’t have a jointer, but I found this link at and thought it was immensely helpful. I followed the instructions to a T and created three jigs using one sheet of MDF just like the video suggests. I’ve used this so many times, I can’t even count. Every rough board that enters my shop gets one rip using this jig. Hopefully this helps some of you out some as well.

there are two pictures. One of the jig by itself, and one with a router showing how the router would be used. The really useful application is the circular saw side though. Sorry I don’t have a picture to go with that aspect of the jig.

Important note : not all routers having the shaft centred on the base – so make sure to maintain the router in constant position all the way through especially those with round bases (unless it is a bearing guided routing).

I second the comment about the router base. Also, remember when using one of these for ripping, that depending on which of the cut-off you clamp it, you need to remember about blade width. Wanna guess why I mention that? Doh!

I’ve got two (one short, one long) I made from some scrap 1/2 ply from another project. They are quite useful. If they didn’t mention it in the video, take a permanent marker and label the jig with the tool and blade/bit used. And mark the router base so you always run the same edge against the cleat.

woodworm. Good call on the router comment. Another thing is that you need to use the same router each time, because the bases might be different sizes. This isn’t the router I use, but I slapped it on there to demonstrate.

rwyoung. good point about the labeling. you can kind of see that I did that if you click the first pic, but I’m glad you pointed it out because I should have thought to mention it in the post. For the router and saw, it is important to keep the setup constant.

I’ve got a couple of these, too, but I’m having trouble figuring out a good way to store them in my garage. How are you guys keeping them so they don’t get damaged?

I’ve got them leaning against a wall, so no, that is not the best way to store them. I would think an easy and good way would be to put a hole through the piece and hang them on a wall. They would take upa a lof of space, but if you were willing to hang all 3 from one peg, it wouldn’t be too bad.

the key is using the factory edge. it is pretty good to get you started with an edge good enough to put on a tablesaw.

Well, it’s been a year now and I still use it all the time. Hopefully it can help a few more people because it is affordable and make relatively accurate cuts. not as good as a tablesaw or store bought jig, but its particularly good for breaking down plywood sheets. Good luck!
