We take tools, materials and equipment and employ them in way never imagined.
Using lawn edging and PVC water pipe as an air dam has to be about as far away from the intended use of these products as one could imagine.
It all started when I bought the roll of lawn edging about 2 weeks ago, unrolled it and put a loaded tool box on each end to straighten it and it didn't work that great. When I took the tool box off one end it tried to roll back up.
So to straighten it I am jammed 1/2'' PVC water pipe into the round end of the edging.
I have completed the aluminum backing/foundation for my lawn edging air dam and attached it to the bumper. Now its time to add the lawn edging. The backing is made of 6061 angle bar aluminum, 2024-T3 and lots of #8 self tapping sheet metal screws.
I decided to use the 2024-T3 because I have had it on my metal shelf for years collecting dust, not used it because you cant weld it and it really does not want to bend.
I did this because the air dam needs a strong foundation or its just going to tear off or bend against the force of the wind and not do anything.
To join the 2024-T3 to the PVC reinforced lawn edging I have decided to use more #8 self tapping sheet metal screws and bonded neoprene washers.
Since lawn edging and PVC are so cheap and light I may double layer it up for increased strength incase I hit another raccoon.
I'm going for about 8'' of ground clearance so I shouldn't hit anything else.
More pics tomorrow before I paint it black.
