Re: importance of depth gauge on stanley 71
George Makowski
>Frank, As you might remember, I posted below in answer to some of your questions about the Stanley #71 and the depth gauge. To recap, it has two functions: 1. it serves to hold the throat closing shoe below the arch of most #71's castings; 2. it serve as a depth gauge when reversed (small end down). So without the depth gauge or equivalent rod, you cannot hold the shoe in place or automatically check depths. The utility of the gauge or substitute rod depends on how often you would care to close the #71's throat or gauge depth with the plane.
Now, that said, it does not work like a depth gauge on a plow, fillister, or combination plane which stops you cutting further when you reach a certain depth. The #71 gauge simply shows you when you have cut to the depth you have set on the gauge, it is possible to cut deeper than the gauge is set.
For a detailed description see Planecraft.
NOTE: Be sure that you are getting all the thumbscrews needed with the plane (three counting the depth gauge and foot) they are 1/4x28, easy to find as machine screws, hard to fine as thumb screws.
Good routing!
