True, that makes a heck of a difference, but the plane I'm whinging about is tight with the cap screw set for what I consider the 'right' amount of lever cap pressure when cammed down. I suspect the problem lies with the cam and slot in the cap iron, but haven't checked it out thoroughly enough. The only time I think of it is when I sharpen the plane, which is always in the middle of a job, so I tell myself I'll do it later. Hah! Like tomorrow, 'later' never comes, does it? Some rainy afternoon when I have time on my hands I'll sit down with the best & the worst & compare each working part of the adjustment mechanism, then I'll try changing one bit at a time on the baddie, until it works like the goodie. If I'm successful, I'll have achieved two things: my stiff plane will work properly, and I'll have a much better understanding of what makes a Bailey adjuster work smoothly....

Cheers,

Cohesion is the word that comes to mind when I think about what I've just been reading between you two.
Van der Waal now that was completely new too me.But I'm suitably young enough to have google lol.
IAN W is right, he must know my mother I don't have the patience to surface lap the frog and blade into a cohesive state(or maybe that's an idea).
Ian with out the W.
I did think straight away after reading your point about the blade sticking to the frog.
Is that not the reason we have a world addicted to petroleum products.
Would not a suitable light oil be a perfect medium between our two co habbitating parts.
Now to throw a cat in with all this co adhesion is all this held down via just one centre point point only a big screw in the centre.!!.
Yet we all know that the design has worked for hundred years plus so far.
And worked reasonably well to boot.
So who am I to mock it.

Cheers Matt
I won't mention I have a small surface gauge and dial indercator plus stand.
Or I will never get a certain mr bloody saw finished.
Wow that's a lot of big words for a simple guy.

My editor is still on strike [emoji52]

my materials science subjects were a very long time ago but I think this sounds like stiction, a form of static friction. As the two surfaces are more highly polished, a greater area of the surfaces make contact and the static friction takes more force to overcome. it' happens with things sliding bearings or joints and the mating surfaces here sounds similar
