I was re-reading the instructions for building my shed and realized the word gusset has another meaning!
- a small, triangular piece of material inserted into a shirt, shoe, etc., to improve the fit or for reinforcement.
- Civil Engineering. a plate for uniting structural members at a joint, as in a steel frame or truss.
a. Also called voider. an area of mail backed with cloth, for defending the armpits or areas at joints.
b. a small piece of plate armor at the armhole of a cuirass; pallet.[/quote]
OK, so other than in relation to the civil engineering explanation, what are you referring to?
you covered it in number one of your post above.
and used in a sentence: “hey, gusset yer trailer yet?”
