Inconsistent front rail pin size.

[Farrell]

Assuming the keys are spruce or basswood or some other similar wood, you'd 
be surprised at how much the key mortises can swell. Get things good and wet 
in there and with the Spurlock mortise sizing cauls I think you will have 
very consistent results. I'm just guessing, but I would keep the old 
bushings wet at least overnight to make sure the surrounding wood will swell 
a little bit. Maybe you need to do a few hours on a wide mortise and see how 
long it takes to loose the couple thou extra width - that's assuming the 
mortises are irregular - perhaps they are not.
