LINKAGE ADJUSTMENT
The linkage on your TENNSMITH shear is comprised of two turnbuckle assemblies (55). Rotation of the
turnbuckles is the means by which blade rake and pedal height is set. There should be no need for this
adjustment on a new shear.
Rake angle settings:
MODEL 36
Use a marker to mark the shear bed 2 inches to the from the right side edge of the table. Next, measure
over 36 inches from the right side edge of the table and make another mark. Starting at the right hand side
(facing the machine) at the designated mark on the table, rotate the turnbuckle (55) until the distance
between the top and bottom blades is approximately 3/8 of an inch. At the opposing end, repeat the
procedure allowing 1 1/2 inches clearance between the upper and lower blades. After you have the desired
clearance between the upper and lower blades slightly adjust the turnbuckles so that they have an equal
amount of tension. That is, if one turnbuckle has more play or lost motion in it than the other, it should be
readjusted accordingly. Once the rake has been set and equal tension verified between the turnbuckles,
retighten the jam nuts (54) and lock the turnbuckles in place.
MODEL 52
Use a marker to mark the shear bed 2 inches to the from the right side edge of the table. Next, measure
over 48 inches from the right side edge of the table and make another mark. Starting at the right hand side
(facing the machine) at the designated mark on the table, rotate the turnbuckle (55) until the distance
between the top and bottom blades is approximately 3/8 of an inch. At the opposing end, repeat the
procedure allowing 1 ¾ inches clearance between the upper and lower blades. After you have the desired
clearance between the upper and lower blades slightly adjust the turnbuckles so that they have an equal
amount of tension. That is, if one turnbuckle has more play or lost motion in it than the other, it should be
readjusted accordingly. Once the rake has been set and equal tension verified between the turnbuckles,
retighten the jam nuts (54) and lock the turnbuckles in place.
