Question Aligning a Foot Shear

Hi Guys,

Just bought my first foot shear (52" King Canada) and I am having problems aligning the blades and adjusting the cutter. Are there any tutorials on this?

Her's a picture;

It should be pretty self explanatory, if you look at it. The bow in the top blade is controlled by the tension bar and adjusting post on the back of the blade.
The slide ways are adjusted with the screws that move the gibs. (Part 9)
The clearance is adjusted by moving the table back to meet the top blade. Any non linearity on it looks like it would have to be done with shims. (I would have to see it to tell. )
They are basic machines, so a good visual inspection will reveal their secrets.
The clearance is determined by the thickness of the metal to be sheared.
The first step is to level the machine. Then adjust the gibs so that there is no back and forth play. Then adjust the front table to get the clearance between the top blade and front blade. Check it at many places left to right. You may have to adjust the bow in the back blade.

I needed to adjust a 52" Tennsmith that I just bought from a local school auction. It was badly out of adjustment.
We had to shear 16G 48" wide and the factory recommended setting of .002 would partially shear & partially fold over the edge.
In the end we set each end of the blade at zero clearance (carefully operate the machine while doing this) and then adjusted the tension bar for the center clearance while rechecking each end.
The other important setting is the slope of the upper blade, if this is correct you'll only be shearing 1/4" or so of material at one time.
Also the machine must be level.
In the end, set with zero clearance we could shear the steel easily.
I hope this helps.
Mike

I'm curious what a dial indicator and magnetic mount might tell you about flex in the process of shearing.

FWIW
