I've just bought a 2' old Niagara stomp (foot) shear. After cleaning, some adjustments and lubrication, I thought I should sharpen the blades.
I would prefer to lick the faces of the blades (the surfaces that face each other) before grinding the tops to sharpen the edges. Usually, people mention using shims if the thickness of the cutting edge was modified. It looks like this particular shear design allows to move the table along with the stationary blade back and forth to regulate the gap between the blades. I cannot see why any shim may be needed to compensate for face grinding in this case. Yes, I realize that some shimming might be required to correct bowing of the movable blade, but it has nothing to do with my grinding the blade faces. Am I missing anything?
I'm also trying to verify the maximum rated capacity of the shear, but cannot find the data. I sent a request to BCN, but don't hold my breath: the shear is quite old with its Ser.# 7977. The blades are 26" long. Does anybody has any info on this model?
Thank you.
