Hi Steve,
It may have worked for you, but the shims do nothing to relieve the
twisting torque on the leg, which would be my main concern. I would
have nightmares about brace welds ripping out of legs.
An outrigger tied to a second leg solves that problem, but by the
time you do that, you might just as well have built a full face
bracket, which can consist of just two pieces of angle and a short
2" OD mast.
