I have percolated on a Taper / Rip jig for quite awhile. I try to render down all the ideas I see on other versions and take the points that will work best for what I want to do. After a few design versions I came to realize that Woodsmith's version had everything I was after and had a simpler, more elegant centering pin mechanism. I scrapped my designs and went with theirs . Some dimensions are modified as I will use this for more than just tapering legs but, except for that, the jig is basically unchanged.
Since this is a combination "build those jigs I've been meaning to get to" and "get rid of some of that scrap" effort, I used some old plywood that has been around way too long. How long? It measures 3/4" in thickness!?! Anyway, a piece of straight-grained pecan will do for a runner. I dado about 1.8: deep to set the runner and make it solid. I have shellac'd these surfaces and given them a good coat of paste wax.
I noticed something funny while cutting the dados for the t-track. I keep using my original 'beater' dado jig to make more jigs . . . why don't I make a better one of these? Maybe he's next. You can see that I have given the shop plywood substrate a tempered hardboard laminate surface for wear purposes. I did the same for the fence.
The recently made sled support comes into play to cut the 'zero' reference side of the base.
The t-track goes on the base.
