Nichols Shear Postscript

I realized that it might be a good idea to provide more detail about how the holes are oriented in the shear blades.  The center to center distance of the working holes to the pivot hole is about 5/8” and they are aligned at about about 60º angle intervals.
Another thing to consider when cutting stock is the shape of the severance surface.  The shear created a nearly perfect vertical break with a flat end which is ideal in many situations.  Sometimes the work favors a hacked severance or scissored severance which leaves a tapered end.  Pick the right tool for the job.
