Look at that zoomed in gap. The tolerance is tiny, nowhere near that. Same reason a small shim won't work.

That's a 2" pipe in a 2" hole. It is snug.

How deep is the hole ? Is there concrete in the bottom ? Can you sink a smaller diameter pipe in the hole . and drill a hole through it . Drill a corresponding hole in the pole and pin it .

Screw a length of paracord or bungie to the house or eve and put a hook on the other end. Then just hook that into whichever corner of the umbrella you want to stay next to the house.

The hole is about 8-10" deep and terminates in (I think) a PVC cap. I'm not sure how a pipe in pipe attached to an umbrella's not going to spinny-spinny just the same. Also given the near impossible task of reversing course on anything that goes down that hole, I'm hesitant to embark on that.

The house is 20-30' away and uphill, so that would be a long rope at head/neck/chest/ankle height unless we did actually tie to the second story. With kids running around I don't think that's going to work, but it would be a close second in redneck-iest looking to the duct tape.

Funny, telling them the precise depth to set these was an oversight of mine, and one is much deeper than the others. I marked out exactly where I wanted them on the surface/drawing, but not depth. Dumbass.

There are four holes total, two front two rear, but generally only worried about orientation of two at a time. Sun comes up behind that pad, passes over and sets in front of.

Spring hose clamp that fits tight on umbrella--maybe bicycle tube under clamp. Notch the PVC to accept the ears of hose clamp.

Wall thickness of 2" PVC is about .15 inches, so many of the notch and slot ideas aren't workable in that space. It's too bad, because the spring clamps would be easily adjustable.

.

Because the pipe that goes down in the hole would have to be anchored at the bottom . Possibly epoxy ? I'm having a hard time describing what I'm envisioning ...

They make cone wedges for this purpose, but not sure if there's enough of a gap in this case. Also not sure if the PVC pipe is not itself "spinny-spinny" as you said.

If the pipe is indeed secure, this might work as the wedge is made of silicone rubber and you would insert the cone first into the pipe, then ram the umbrella shaft through it for a nice, tight fit.

Me. Cut several notches in the top of the PVC. Cut hole in the umbrella tube at the correct height. Insert pin and drop into appropriate notch.

This could work....

The kkina wedge is too big. The HD one might just be thin enough to snug in there a bit. Added to my HD cart for further investigation. They seem to be in stock locally so I can hold one.

The cone wedge might still work, it would just stick up higher.

At any rate, have you ascertained whether the PVC pipe itself is secure? A quick and dirty way would be to jam some popsicle sticks in the gap and see if it spins.

Thanks again for the ideas. As noted and pictured, the tolerance is pretty tight and the size allen wrench that would fit in there is VERY small, to point it makes no difference. Might as well be round.

Didn't have tools with me to try notch/pin ideas, but will be back in a few weeks and try that next.
