Right.....compression springs. Thought about putting a shim under the bottom, but that would
entail building a spring compressor to work with those 2" (approx) diameter springs.
Nope, this shear is in "like new" condition. Nothing bent, properly lubed all moving parts, everything
is free to move, just appears that there is not adequate spring to return it all the way.
Tried a couple of 3/8 Unistrut beam clamps with screw hooks, one on the very front lip of the table and
one below it on the foot pedal. This is spaced out so that a pair of a 3/4"x8"x.110" springs put just enough
tension on the pedal to pull the blade all the way up. Problem is.....the stroke of the foot pedal at that point
is about a full 10". My pair of six dollar 8" springs after the first stomp are now 11" springs. You can't stretch
8" tension springs out to 19" and expect them to come back to their original size. Way beyond their yield point.
So...back to the drawing board. Might see if I can find one of those garage door tension springs Don, I'd have
to cut it way down cuz with clamps and hooks, there is only that 8" distance to fit one in there.
These shears were/are all made the exact same way whether they are branded Grizzly, Northern Tool,
Penn Tool, Baileigh, Woodward Fab, etc. This couldn't be the only one that was sent out with a weak set of
return springs. .
