I messed up a cutting a piece for my UQ, no problem really cause I bought extra but I think I can make one beak of the piece. I looked in my notes and have that the vertical is about 50"and I had put 13" for the top, but I don't have a length for the bottom.

It's not coated just 1.1 but I figure it will be good for wind, and I can treat it is I decide to later.

How long is the lower side on average? any experience and comment appreciated...
