The ancestor of my butt mortise plane *LINK*
Bill Houghton, Sebastopol, CA
>Some years back, I built a butt mortise plane, when I had to go in and change the swing of the bathroom door in my uncle's house (he kept falling down, and, with the door swinging in, no one could get in to pick him up, so I changed it to swing out instead), and wanted to be able to move fast. Indeed, the entire time I was working, he was in the living room grousing like mad that I didn't need to do that to his house.
Someone recently tried to sell my plane's ancestor on deBay. Nice to know that a similar design was, apparently, once factory made; convergent evolution can be such a comfort. Mine pictured below.
