It sounds like it's been your experience that while pulling the trigger, as the sears start losing the overlap, you simultaneously
loses trigger weight . I have super sized some sears below.
I'm suggesting that the load stay's constant and as your unit area goes down, the unit pressure goes up.
100 pounds on 100 sq in = 1 pound per sq in. 100 pounds on 50 sq in = 2 pounds per sq in. And so on.
I use the smallest dollop of Krytox on my sears too.
I thought I had read that some trigger companies say to use Ronsonol lighter fluid to clean the unit. Is that what you mean??
Below is stuff from the net....
""Frictional force increases ... When the contact area is made smooth then the molecular forces between surfaces increases this gives rise to frction.""
Anyone who has wrung gage blocks together has felt the increase in friction from the molecular forces.
""Since pressure equals force divided by the area of contact, it works out that the increase in friction generating area is exactly offset by the reduction in pressure; the resulting frictional forces, then, are dependent only on the frictional coefficient of the materials and the FORCE holding them together.""
"" Friction is Not Dependent on Surface Area ""
""A fascinating property of friction is that it is not dependent on the surface area in contact between two objects. This seems counter-intuitive. Here’s why this is the case: “Although a larger area of contact between two surfaces would create a larger source of frictional forces, it also reduces the pressure between the two surfaces for a given force holding them together. Since pressure equals force divided by the area of contact, it works out that the increase in friction generating area is exactly offset by the reduction in pressure; the resulting frictional forces, then, are dependent only on the frictional coefficient of the materials and the FORCE holding them together. ""
If you have one pillar the total friction is μN. If you have two pillars each supports half of the weight, and thus exert half the normal force, so the total friction is μN/2 + μN/2 = μN.
