I've read and heard that "light pressure" should be used with the new diamond wheels and to "let the diamonds do the work".
Well, I am wondering just what does that mean "light pressure". That is very qualitative, as what is light pressure to one may be heavy pressure to another.
Can "light pressure" be characterized in some standardized manner, or quantitatively, such that every user can correctly interpret it and use the appropriate pressure on the wheels. Does it constitute just the pressure of the weight of the jig and tool being sharpened? Just a light touch with a finger or two, or a very light "lift" for tools that do not contact the wheel by their own weight?
My knife edge sharpening testing instrument (Edge On Up's PT50#)(http://www.edgeonup.com/index.html) measures in grams of force required to sever a standardized media and sharpness is rated according to an accepted standard (BESS scale of sharpness)(http://www.edgeonup.com/eou_new_2016_008.htm). (My PT50 happens to the the "A" model which measures in 1 gram increments. The others are 5 and 20 grams.)
I wonder if grams of force could be a standard way to characterize the necessary pressure for the diamond wheels.
I wonder if the PT50A could be rigged in such a way as to measure the force (grams) applied by just a tool/jig resting on it, and then with a finger of pressure, etc.?
I am asking sincerely, as I am spending a bunch of money on the wheels and sure as heck do not want to abuse them and dull them prematurely.
