This video made me giddy with how clever these jigs are! Especially love the second one.

Be right back. I’m going to go in my shop and work until you’re needed again.

Very informative, I never knew that they made "Under Sized Plywood bits".... thank you for sharing. Love your videos. 👍👍👍

That first jig could also be used with a circular saw, I think I will make one for it.

HA - I made the first jig just yesterday! I've seen Tamar use it on 3X3 Custom a few times, which is where I learned about it. Anything that keeps your cuts straight and eliminates the need to measure is worth way more than the scraps you use to build it. I made mine 4 feet long, and I'm guessing I'll probably make another little sibling sometime in the future . . .

The hinged jig is a must have. And the t-square one, with the offset baseplate is genius. Never seen that one. It's going in my list to make!

Perfectly timed. I was planning to make a router jig this weekend. Your video has given me some ideas on how to simplify and improve it. Much appreciated, and, as always, great job!

I built a similar hinged jig a couple of years ago. It's become the most used jig in the shop. The T-jig is a great idea. Thanks

I just saw a video yesterday by Tamar from 3x3 where she used that first jig. It’s GENIUS!

I recently got a cordless router and replaced the stock base plate. They recommended a centering cone but Instead of buying one I just turned one on my lathe. I drilled a 1/4” hole first to establish the center. This video was very helpful. 👍

The first jig I have previously seen on other videos. HOWEVER, the second seems more versatile. Thanks for sharing that with us.

I've been working in rough carpentry, mill work, and fine woodworking for over 20yrs now in that time I am finding Metric Router bits my go to for most plywood dados and rabbets.

I finally built the first jig. I don't use it a lot, but boy, am I glad to have it when I do! It make things quick, accurate and easy. Thanks James!

I've been using similar jigs for quite a while. They are easy to make and work well. Thanks for presenting your versions, Im sure this video will be a great help to many.

As soon as I saw the thumbnail photo I knew exactly what I was seeing. The simplicity of it is brilliant. It’s something I’m going to add to my shop as soon as the weather warms up.

I've been using the first jig for some time now, but without the hinge. Once the fence is clamped in place I just remove the small piece and set it aside. Of course they're marked so I keep them together, and hang them on the same hook.

I accidentally invented a variation on the T-Square jig, but instead of using an additional base plate, I used a flush trim bit that referenced against the fence, and yes, cutting through the edge piece gives you perfect alignment to marks for cutting positions. I may not be as dumb as I think I am.

ALWAYS worth my time. Thanks for sharing, JH! I have a bookcase to make and these jigs will help that bookcase to be better than it would have been before viewing.

James, I’ve used a 4’ drywall T-square for your second jig for over forty years. They are aluminum, fairly light, but stiff and will not warp or loose square.
