Check out
Old Fart Woodworking on youtube.
Kevin has been sending out some mitre boxes to folks and rather than leave them on their own to figure things out this seemed like a good way to start.
This first box was developed and then patented by Justus A Traut in June of 1877. In the video he has dismantled the box and walk through reassembling and setting it up.
There will be a few more videos added as time goes on.
