In this video I make some simple dogs for my workbench.
Before I started, I wasn't sure I'd need/use them, but fancied giving it a try - and now they're installed I haven't stopped using them
I started with a scrap of oak that was around 33mm square which I'd use to make the dogs.
I picked the back left hand corner of my workbench for a few reasons - I have access to the underside of the worktop in this area, it's also in a good position to plane/sand etc, and finally it's out of the way of the main surface area of the worktop.
