fixing clicking knuckles

[Jon Page]

You should always remove shanks and flanges from the rail in order to
avoid any risk damaging the centers. This goes for knuckle replacement,
hammer removal and sometimes bolstering. Also because if the knuckles
need replacement, they more than likely need repinning and filing which
can be expediently done on an oscillating spindle sander or drill press and
drum sander.

Since you're doing all that, it's an opportune time to graduate the 
Strike Weight.

It is also important to press the knuckles in with a caul to try to get them
to a uniform in height. Knuckle height is an overlooked refinement in prep
for regulation. Uniformity = close tolerances = even regulation = a 
consistent touch.
