I think I’ve done a reasonable job improving my dovetail jig.
That 12 inch Porter Cable model; it has some problems with repeatability. The reference marks are quite wide and positioned in a way to give a lot of parallax error. There was no real way to quantify how far you’ve moved the template in and out, which meant it’s basically guaranteed to come out of alignment. So I took a knife to it. Scribed the alignment line around all the tines and put graduation marks on the brass thumb wheels. It’s a lot easier to be deliberate in adjusting this thing now.
It still needs a few other things here and there, and I need to put those alignment marks on other templates. But it’s a start.
And here are some using my new “dial it in” method. Cut a test, measured how far off it was, adjusted the template that far and it’s done, no guess-and-check-oops-too-far.

That’s awesome! Dovetails a plenty in your future!
