I am wanting to cut some 1/4” wide/thick tenons in cedar fence picket material. The problem is that the rough sawn cedar is not all the same thickness. I was wondering if I could stack two table saw blades together with a 1/4” worth of washers and create essentially a “dado” blade that would cut 1/4” tenons. Or, does anyone have any other ideas? I am building some small rough sawn table displays for a wedding reception and think tenons would be the easiest way to join two pieces of materials together for this application. Thanks

The technique you describe is doable and
described in various books I’ve read.

Whether you want to go to the hassle of
fine-tuning the spacing to match your mortising
tool is another matter.

As long as you reference the same face for both cuts, it won’t matter. Just mark one face of each board with a pencil, crayon, tape or whatever and make your cuts in relation to it. You’ll have to readjust whatever jig you’re using for the second cut. Use a piece of scrap for setting up each cut before doing the production pieces.

Assuming you are using a tenoning jig, it could be done with two passes on the TS, always referencing off the same face of the part being tenoned. First pass- cut all the right cheeks. Reset the blade, then second pass- cut all the left cheeks. Your tenons will all be equal thickness now, but you will have the potential for some variation on one side of the part.

I used a tenon jig like this one for awhile.
It was easy to make and referenced off the
fence so adjusting for cut 2 was as simple
as moving the fence over. Design by
Frank Klausz.
