PICS!
This thread is useless without pics!
Here is what I built yeterday with 1" & 3/4" Aluminum square tube & 3/8" all thread
I did not want to drill into my bucket so I installed this onto the outside of the bucket & used the all thread to squeeze it tight to the bucket.
Should hold light signs & plex faces with no problem.
The uprights are 3/4" aluminum square tube welded to the front of the 1"
The pads on them are pipe covers from Home Depot.
I weigh 185 lbs and I stood on it with no problem.
Hope this helps.
