On my latest table design, the aprons need to be rebated to fit into the legs, and while there are many ways to achieve this, with a ~46” long board, some become just too difficult or unsafe to perform. So I considered my options, and decided that I would prefer to use the table saw and a dado blade as opposed to a router. Now I run into the issue of the board not being supported safely by the miter guage face due to the length. So I started researching the possibilities and came across a company called 80/20 that makes aluminum extrusions. Here is my solution, 1”x3” smooth face extrusion (1030-s) which I included a flip down stop from lee valley for repetitive processes.

How much deflection do you see on the unsupported end at full extension?

I use the beam (same kind of extruded aluminum) from the my oval jig set as my extra long miter bar. You can get them from most any on-line woodworking store that sells jig parts. Mine happens to be blue since I got it from Rockler. I think Woodpeckers sells a red version.

- Holt

As you see it set now, I can only see approximately 1/8” of deflection at the unsupported end. Small enough the angle change to the blade would be imperceptible.

What a handy upgrade

-- Norman - I never never make a mistake, I just change the design.
