I needed some square wooden dog for my workbench dog holes. The Lie-Nielsen website wanted $50 for the pair. I knew a guy who bought them and I asked for the dimensions and made my own. Perfect replicas.
Good job with them. It seems that the manufacturers are only giving themselves a bad name by overcharging for items such as this. Actually I can't see why anyone would not build their own anyways. That's one of the things I like most about having a shop. I don't have to rely on a store to come up with whatever I want or need. I am only limited by my own imagination.
ScoFF, I would take the time to sand a round-over on the corners and top of your thin tensioners, as they are they might tear the top of your workbench if its made of plywood or damage the dog itself when removed. Nice work on the pieces, Pat
