I've got workbenches that some people would think are antiques, built when I moved into my house in 1972. Basic construction is Square A-Frame 2x4 legs and many longitudinal 2x4 stringers topped with 1/2" plywood and an 1/8" masonite worksurface. The frame is still strong enough that I very often stand on both the top and the lower shelf to reach high things.
I recently bought some bench dogs and then started wondering how thick the wood where the holes are drilled has to be to provide good retention. Over the legs, I've got about 36" ;-), over the 2x4 stringers, I've got a measured 2" and much less between them. Is the 2" thickness sufficient to hold the dogs or do I need to provide additional thickness where I want to put them?
