I needed to make a face frame for a small project, with material only 1/2" thick and 1-1/4" wide. Decided to use the Jessem jig I purchased from Bill Huber, with the .25" guide bushings.
I use the .25" aluminum pin to reference off the ends of the workpieces, I find this guarantees that the ends of my pieces will be perfectly aligned when it comes time to assemble the joints. Within .001" or so. Just amazing.
I love this jig.
Mr. Huber also sent me a set of his stops for the Paralign jig from Jessem (which I also have). I have a project coming up where I'll be using that jig. I've already tested the stops, they are brilliant. they make the process so fast and painless, I'd dare even say foolproof. The stops are actually better than using your finger. So I'm looking forward to that project. Just need some more straight-grained fir.
I'm including pics of the face frame I made w/ the .25" dowels. Two dowels per joint.
Oh and yeah, I really do clamp workpieces at an angle like that.
