I promised in a thread that I'd post pictures of the jig that I was going to make when I did it next, but I can't find the post. So I'm hoping that anyone that may be interested could see it here.

The router bit has a bearing on the bottom that rides the jig
Here you can see the detail that the bit rides on.
Starting end bar
Completed end bar

I have to flip the frame over to rout both sides, but the de-sta-co clamps hold the bars down well so my hands are far enough away that it's totally safe to use. I also have a block that's cut one size for where it contacts the top bar and another piece that holds it where it attaches to the bottom bar. These 2 blocks keep it snug and hinders the frame from exploding. I did about 100 frames worth of end bars in about a half hour.
