Last month I was sitting under our main awning in the desert when a sudden, unexpected, renegade dust devil lifted one end of the awning and bent the rafter arm bar and put a slight bow in the arm tube.
Upon return home, I ordered the appropriate replacement rafter arm bar and tube from Awnings By Zip Dee
(See details in my posting, "Desert flowers and devils
I installed the new rafter arm bar and tube.
The slight bow in the old rafter arm tube self-corrected itself when the bent rafter arm bar was removed from it.
Larry used a Black & Decker Workmate workbench vise and PVC pipe to straighten the bent arm bar. The photos below were taken after he straightened the bar and are presented here to show how he did it.
First he placed the bar on the flat workbench surface to check for straight (true) bar alignment and used a marking pen to mark the bent section.
He marked the bar in 3 places and placed the bar in the workbench vise at the 1st mark for bending with a PVC pipe (See post below).
