Okay. We're going to drive a stake in it. Just ordered the hardened rod and as soon as we get the rod in we're going to make the new steel platens. Let us see how/if it works and then we'll go from there. We need to produce a nice, broad range of effect i.e. really good edge = 50 and really bad edge = 300 so that differences are easily discernible. If it actually turns out to be 20 and 400 then fine but we don't want a range of 20 and 45 although 20-45 might be actually telling the complete story already. If you recall, people used to get thrown in jail for suggesting that the earth wasn't the center of the universe so if it turns out that indications are that there isn't much of a measurable difference, no matter the sharpening technique/steel/sharpness level, please provide references for a good bail bondsman.
The relationship between edge impingement area and force is just going to have to be trial and error. We're going to begin with .3125 (pin diameter) and 5 Lbs. (added weight) and see what we get. We like 5 LBs or there about because that's about the force required for a sharp knife to cut a potato in two and it's a very manageable amount of weight to be working with. We don't want to be placing 50 LBs. on the piston platen so if adjustment is made it will likely be made by adjusting to a smaller impingement area.
Our experience tells us that test apparatus like this, right off the bat, give strong indication that there are significant differences to be discovered and in a reproducible fashion or they don't on one count or the other. This little gizmo has some hoops to jump through and some simple tests to pass before it sees the light of day. We should have something to report, thumbs up or thumbs down, end of next week.
