Really looks fantastic.
Do you have a brace down the center --can't tell from the photos?
What did you use to attach the 2 lengths together? Did you bend them before putting them together or after?
How did you figure out how much to bend them to fit your 10' width?
Finally, how did you connect the metal rails to your wood frame that makes up the base?
Sorry about the 3rd degree but you really did a nice job.
