/Hello, I just Picked up a Grizzly G4011 3in 1 Brake Shear Roll
machine.
When I got it home, I tried to rotate the crank and the right
"leading"
side of the cutter blade would bottom out against the right side
frame.
It is supposed to clear to rotate completely to roll metal of
different
lengths. The cutter bar bolts to each side arm so there is no
adjustment
to raise shear blade. [...]
I cannot figure out why the right side of the blade bottoms out
against
the support frame just enough to keep it from rotating. I remove
the
shear blade and it rotates fine. [...] The only thing
I can do is notch the side frame a little to let the blade clear as
it
comes down. But I was wondering if anyone has experienced this
.[...]

On my 30" 3-in-1 similar to that one, I haven't had any problems
rotating
the handle continuously when making cylinders. I have had the
problems
that Jim Wilkins mentioned, where shear adjustments are finicky and
thick material doesn't cut well. I mostly use my 3-in-1 for bending
pans and trays after cutting out the metal with a shear like

which can cut nice straight lines quickly.

Maybe there was a manufacturing error on your shear blade and it's
slightly too long. I think it would be a mistake to notch the side
frame; that might allow a crack to start. Instead grind the end
of the cutter blade and make it a bit shorter.

One side of each blade has a 5 degree bevel, the other is square. The
Grizzly manual mentions this but doesn't give specific installation
directions.

I experimentally put the bevel side down on the upper blade and the
square side back to meet it on the table. IIRC they didn't seat
completely flat otherwise.
