I'm making a workbench and I've seen lots of examples of slots for bench dogs that have a notch cut at the top. I'm making my own bench dogs that will have a "spring" formed by a piece of pine that fits into a recession under the head and attached to a taper at the bottom of the dog with a screw.
My question is: should I cut a notch in the workbench slots or just leave it straight? Also, the bench dogs will be rectangular (not round) and at a slight angle.
Thanks!
