Step 2: Allowing for Metal Thickness
The clamp assembly must be adjusted to allow for clearance according to the thickness of the
material being worked. To adjust the clearance on the clamp assembly, slightly unclamp the clamp
handle, loosen the bracket lock handle and turn the adjusting bracket screw. When the correction is
made, retighten the bracket lock handle. Move the clamp back from the apron at least one and one
half times the thickness of material being formed when forming up to 18 gauge (.050) material, and at
least 2 times the thickness of material being formed when forming 16 gauge (.0625) or more. Re-
check clamping pressure.
If the clamp fingers are too far from the edge of the bed fingers, a larger radius may be made in the
material. If the clamp fingers are too close to the edge of the bed fingers, the clamp fingers may be
damaged. Lock the bracket locking handles for repeat bends.
