I didn’t design this chicken crate, as it is a half size copy of the wooden crates from about 100 years ago. The only change in the design was the addition of corner brackets. Most of the surviving crates that I have seen have damaged corner dowels, so I made the brackets. The only concern was how to clamp the corners. What I came up with was to use two different size C-clamps so one would “leap frog” over the other. To keep the clamps from bruising the wood of the crate, I made some cauls that would spread the force over a wider area. Works great.
