[TowerTalk] mount pipe for vertical

[K2VI]

Ok so tomorrow is the day i start this project. I have a 5' piece of 1 1/2" fence post pipe. It will be almost 4' cemented in gound and 14" above ground. I will have a zero five 43' vertical on the pipe. All i hear is schedule 40 plumbing pipe however i have on hand this fence pipe. I see no reason not to use it since the vertical has very little wind load. Also this pipe was used holding up a cushcraft A3S 5 feet above the thrust bearing. I just want to make certain before cementing. thanks in advance.
