8NTX,
Actually mine did come with the sleeve. I installed it per the manufacturer's instructions. If you didn't get one, just head on down to the hardware store. It is just a piece of PVC.
Here is how I planted the pole:
1. Dug a 12" hole 30" deep with my PHD.
2. Used a shovel to "bell" the hole.
3. Dumped 1 1/2 bags of play sand in the hole.
4. Put sleeve in middle of hole.
5. Filled in rest of hole with 2 bags of quickrete.
6. Put flag in sleeve before concrete cured and plumbed sleeve.
7. Quickly removed pole and waited 24 hours.
8. Insert Pole - Raise flag!
We have had recorded gusts of over 80mph in the last six months. The name of the place I live is "Windy Hill". We do have clay soil, but the flag pole has been rock solid.
I'll have to take some more pics of the flag with the tractor in front. /w3tcompact/icons/smile.gif
