Shear bow
Over a period of time the frame which carries the lower shear blade may go out of
alignment, resulting in shear cuts which are not straight. To correct this problem, the bolt
attached to the adjusting bar should be adjusted; tightening the bolt will cause the ends of
the frame to bow outwards whilst loosening it will bring it in (see figs 15 & 16).
Shear Blade Adjustment
To check the alignment of the blades, lower the upper shear blade as far as it will go and
examine the gap between the blades. If one side of the lower shear blade is further away
from the upper blade then the work table will need to be adjusted (see fig 17).
Loosen the screws which secure the work table to the frames and adjust the screws
underneath the table until the two blades meet evenly along their length. Re-tighten the
table securing screw (see fig 17).
Bending Die Adjustment
If the line-up of the upper dies becomes uneven for any reason they can be re-aligned. Cut
a piece of hardwood to the same length as the dies, ensuring that opposite faces are flat
and parallel. Raise the upper dies to their highest position, place the wooden gauge on the
lower die, slacken off the clamping screws (see fig 9a) which secure the upper dies and
allow them to rest on the timber. Check that all the dies are lying flat on the timber and then
re-tighten the bolts securely.
