We are changing location - from WalMart to a store in town, owned by a church member. The stand will be on the corner of the parking lot and we can leave our stuff overnight in the store or even leave a table and umbrella in the parking lot if we want to.
We are going to try to mount the 8' umbrella permantly by driving a pipe in the ground. The reason is, that we have elderly ladies who volunteer to tend the stand who cannot handle the umbrella. The umbrella we ordered raises and lowers with a hand crank, and I'm thinking they can simply lower it and wrap a bungee cord around it to keep it from flopping in the wind. Someone could steal it, but we're gonna take that chance.
I'm planning to drive a piece of 3/4 galvanized pipe two feet deep (there are utility lines at three feet) and clamp the umbrella pole to that with two hose clamps. The location is sort of rocky and hard, but no asphalt right there, so I think I can drive the pipe. Think that will work? If not, we can make a 1-1/2" base to drop the pole into, and bury it in concrete. I just hate to do anything THAT permanent in his parking lot - but we probably could. I could also put the base in a 5-gal bucket of concrete, but that would blow over, or get tipped over and damage the umbrella beyond repair.
Anybody ever install a big umbrella with a semi-permanent base?
