I think I'm obsessing again. Everybody knows that you bent 
front rail keypins slightly to evenly space keys. But when I do that I get 
increased key friction - which seems reasonable as the keypin is no longer 
parallel with the long (depth) axis of the keypin mortise. But I hadn't really 
noticed such a problem previously, nor have I ever heard anyone address 
this.

I'm doing this on a keyboard with nice new key bushings. 
When the pin is aligned with the mortise slot, there is near zero friction. But 
when you bent the pin to move the key over, friction picks up real 
quickly.

So what's going on here??????
