The HS forward spar web, once the bend relief notch has been made, needs to be bent upwards by 6 degrees.
This will match the 6 deg bend in the HS710 and HS712 reinforcing angles.
I clamped the web along the bend line with two pieces of wood, and then laid the flat web against the bench, place the HS710 angle along the upper part of the bend line, and levered the semi-spar against it until the required angle was achieved.
