Hi Scott

I think the solution to your problem is to make up a radius bending tool which fits under the fingers (nose bar) of the brake to soften the bend and eliminate the sharp creases your standard fingers are producing.

With reference to the attached pic, a simple radius tool comprises of a length of round bar, say 10mm (3/8") "a", welded to an equally long length of flat bar "b" which is clamped between the work piece and nose bar.

Some brakes can be adjusted to move the top nose bar clamp back far enough to avoid the radius tool from striking the apron as it rotates upwards on the bend. My brake which has individual removable fingers can't do this, so I have to remove the nose pieces from their holders and fabricate a tool which clamps into the holding slots to get the right positioning of the tool.

Please note that the further back you position the tool from the apron, the gentler the radius you will create with each bend.

Hope this helps
