I have a Sjoberg's Elite workbench. One incredibly annoying part about it is that it has 1" dog holes, instead of 3/4" dog holes. Now they make 1 type of hold down for them, and nobody else does, so all of those neat accessories for dog holes aren't usable.
What would be the best way to reduce the hole size to 3/4" to make them more usable? I've thought of metal bushings, but I wonder about other ideas.
