I've tried using a direct link and some of the guys complain they can't open the pictures. This is the only way I get no complaints. I don't own the site. The owner asked me to moderate it for him and I post my construction projects there that I think will help fellow beekeepers.
There are different ways to make box joints. The most common is to use the miter gauge with a block attached. After using this method for many years (since 1968), I found a better way to do it (1997) and I would like to pass it on so others don't make the same mistake I did. If someone has a better method than this one, I would like to hear it. With this fixture, there is no setup. It is dedicated to this one operation. Just put it in the slots and start cutting perfect joints.
I have a dovetail fixture and use it for other purposes, but this box joint fixture is the only one I use for beehives.
