Not a bad idea and I think it is always better to err on the side of slightly below the line anyway for reasons stated by others.

I will also say that I have observed sliding frictions with this arrangement when action ratios are screwy but when it's dialed in the sliding friction is either eliminated or reduced to non consequential levels. Since all this has now been kicked around a bit I offer this interesting piece of the action geometry equation which Steve Bellieu shared with me & that is ... There seems to be agreement that optimally we set up an action with new parts & so the full capstan movement divides the magic line. Right? But, what happens to that beautifully handcrafted line after the wippen felt & knuckle crush significantly? The hammer line drops, often in large degrees, the first 100 hours or more. Then we automatically reset the blow distance by....raising the capstan 1/2 to 1 turn. right? So now the magic line is already starting to be out of compliance with ideal. Steve does beautiful Stanwood action protocols with David Andersen & he likes to set things up so when the parts are new it takes a bit longer for the capstan to cross the line, so that when everything settles out the action is more likely to still be closer to the ideal set up. Clever aye? Well I thought so anyway. I particularly enjoy setting up Teflon accelerated actions with new parts & angled capstan lines to put the accelerate back in accelerated. good discussion Dale _____ Worried about job security?
