Re: No tear stained defense needed..

"""As a formula, or mnemonic device, his litany was that the mouth opening
(Jeff's aperture--another of those Latinate terms) should be no wider
than the shaving you want to produce, and the distance from the edge of
the cap iron to the cutting edge should be no more than the thickness of
the shaving you want to produce.""

I'll have to read this later, but all I can say is GAHHHH.

I'm sure there's some good stuff in it, but I wrote an article in 2012 at the time that I did (Through Bill, I told PWW at the time that I wasn't that sure what I'd come up with would stand the test of time, and a magazine article is a good way to get preliminary information put into permanent status) because people were throwing around numbers in the thousandths like this (shaving thickness equal to projection, etc) and talking about how they'd like to pair it with a closed mouth (extremely problematic).

Until patrick goaded me into it, I never measured a projection set - I think it's a waste of time. You can tell what the plane is doing by the shaving and the surface, and make adjustments as necessary and then do what "looks right" once you develop the sense. That is how we do pretty much everything that I can think of that is other than a straight line or parallel surface to a specific measurement. Measuring an edge or set is just a good way to ruin an edge or do something dumb because it "matches the instructions".

I get why Warren has always said this is a "subtle thing" instead of giving paint by numbers. It's subtle, but it's simple, and it is one of the ultimate examples of repetition providing improvement, even if you're not trying for improvement.

It also allows something else listed in that conversation, which is concern for surface uniformity rather than absolute sharpness. The washita is a fabulous stone to pair with the cap iron. You can eventually get almost as good as a finish stone with it, but the edge is extremely uniform and stays that way until the plane will no longer stay in the cut.
