Hi LJs, my workshop has a resident with a serious mental disease… My router fence acts like a dovetail jig. Wait a minute. It is. At least some sort of. OK, I’ll play along. I give it a dust hood. (photo 4) Now it sucks. So much that my hands are freezing after using it.
Joking aside, I had a piece of s… commercial half blind dovetail jig that I tore apart and reused the clamps of it. That jig came with 3 templates: 7/16” & 1/2” & 9/16”.
I was just about to make a 20mm template when I realized that I could use my 5/8” 7° dovetail bit with the 9/16” template with a 14mm bearing on the bit. (photo 2)
The ball bearing purchased. The bit slightly modified. Let’s try the template. But wait. That aluminium template was too thin to use it with this router bit on 20mm boards. All right, let’s make a copy of it in 12mm thick beech plywood. (I think it’s the best template material by far. Do you have it in the States?)
Why the router fence? Because it already has two sufficiently perpendicular surfaces on it. Since I just wanted a HBDT jig exclusively for 20mm thick boards, no adjustment slots are needed to cut on the fence. I only had to screw the fittings very accurately on the fence. Well, I use the fence much more often than a HBDT jig, so when I need the jig, I just screw the fittings on the fence.
It was a dream to work with it after I added the dust hood feature to it. It works with a 4” hose. (photo 4)
The last photo shows the test piece.
I hope I didn’t offend anyone with anthropomorphizing a router fence.
Thanks for the feedback,
