Here’s a jig I made to rip 40” long tapers that go from 3/16” at one end to 1/2” at the other.
One could band saw these out and then do the finishing on a planer, but I wanted to see if I could get glue-able surfaces right from the table saw.
It works well, and the surfaces are very smooth and consistent.
I’m making a chair prototype with laminated curved back legs. The wood I used here is just construction lumber and it has too many flaws to really be usable, but the tapers came out as nicely as I could have wished. Last picture is the tapers ganged up to show how the leg will taper from 2” to 3/4” over its length. The four layers will be glued and clamped into a curved form.
