Stanley made its #72 chamfer plane from 1886 until 1938. It is a handy plane to use because it makes uniform chamfers quickly. In 1909 they added the bull nose attachment and from 1887-1918, they made a version with a beading attachment front called the #71 1/2. Here is a picture of the plane and its different versions.
The back end of the plane has a vee shaped sole and the frontpiece is flat. It adjusts up and down to control the width of the chamfer.
Here is the front of the beading attachment. It was supplied with the same six cutters that were shipped with the #66 beading shave.
I really like the #72 and have had many through the years. I always send the good ones to collectors and keep the problem children. My user plane is nothing to look at but works just fine. It has holes drilled in the vee sole. Sometimes users would install a large block of wood to use as a flat sole. This one had been modified for that. In addition, the previous owner ground a nip out of the mouth. That was a problem for me because of the blade. You see, this plane has no blade adjuster so the blade has to be set by hand. It is easy to line it up evenly, but depth of cut is tricky and I use the mouth as a reference. The divot in the mouth made setting up blade depth vexing, so I made a new sole for the frontpiece.
This sole looks nasty, but it works like a charm and makes setting the blade easy. But there were a few more issues. For some reason, these planes often get separated from their blades and keepers. The blade on this plane is a scavenged block plane blade and the keeper is one I made from a #78 keeper.
All of these modifications make this plane a real goat. There is something mismatched or repaired at every turn so the collectors run screaming from the room. But as a user, this plane excels. I love it because I can keep it in the shop and not worry about a little rust here and there. It rewards me by making wispy shavings and great chamfers.
Remember to add chamfers to your projects. This joint of yore will dress up your projects for very little effort. Pick up a #72 if you can. These are handy planes. And remember that planes do not have to be perfect to make perfect joints.
