I posted this raised panel attachment that I made to enhance the versatility of my tall router fence v2. Both have served me very well. On a current project I am using the raised panel jig to hog off the bulk of the material on some drawer fronts. I must be a whimp because my wrist was actually sore today from winding and unwinding one of the knobs so much last night. The holddown bar is actually a curved caul of red oak so it does provide a good bit of torque. The downside to that is tightening it using a little knob was tedious.
I took one of the drawer front cutoffs and made this little guy.
The long bolt is held in place by forcing the 7/16" hex head into a 7/16" counterbore. The same knob (a Lee Valley snap-in knob) is used on a free spinning 1/4" bolt with a nylon insert lock nut inserted into the knob creating an axle of sorts.
Much easier now .
