Does your cut stay straight with the angle? I have some difficulty
with the cut always pulling toward one side using a lever shear (which
admittedly has an even greater angle).
The bungard PCB shear I know only has a very low angle or none at all.
But it is sturdy and you need quite some force to cut wide PCBs. (I
guess that is why the larger manual sheetmetal shears have heavy
weights on the end of the lever, to give it some intertia, or is it
just counterweight?)

I increased this by shimming up one side almost 3/16ths. I cuts thick PCB like a champ now. When I have time, I'm going to remove the shims and cut/mill the the other end down.
