Hi Wim,

Checking has more to do with tail length, contour, roughing and the
backcheck leather, height and angle than regulation.

Hammers:
	Tail min. 3/4" from underside of shank
	Contour, radius 1/2 the shank length, center to center 
	Roughed with 80 grit paper
Backchecks:
	Nice unworn, undry leather
	Height set to 1/8" above shank at rest and 1/16" below tail at drop.
	Angle set so hammer cannot be tapped past check but can be driven 
deeper with firmer taps, about 68 degrees from verticle.

Make sure keys do not chuck.  Springs should not be overly strong.  Try
new leather.  

Others may have other suggestions.
