Metal Pole for Eagle Scout Project

Why does it have to be metal, the siren in my town sits atop a telephone pole?>>

Just a thought, I would think that a telephone pole would more readily available.

I take it that you figured out the 3 phase issues for this project?

Have you done the proper required spotted owl impact study for this project yet?

The feds are going to ask you.

Hi All,

Yes JW, I want to thank everyone for their help again. We reached an agreement with APS. We already had a pole for the siren at the fire house that wasn't being used, so that was perfect, but it was estimated to cost $15,000 to bring 3 phase out to it. So we compromised and agreed with APS to bring the siren closer to the three phase power that existed at a well, and move it away from the fire station to the location of the well, and they agreed upon those terms to donate the rest should we do that. So before a pole wasn't an issue, but now it is. I suspect it will be easier than finding the three phase power.

Thanks again everyone for your help on that issue and your help on this one!

By the way the city told us it had to be metal, not wood. They said wood is too dangerous for a 2,700lbs siren that rotates. They said it had been done in the past before, and had worked, but it was just one of those things where they said that we have to use metal to get city approval. They said wood splinters, and has been known to fail before. So a wooden pole would be simple, I agree, but it is just regulations we must follow.

If you consider making a concrete pyramid that is 10' tall that then has a short pole as needed for mounting... A central core or external (less security) pipe would be used for the power - plan ahead on the size and design naturally.

I'm getting to the point that a pole 20' tall might be hard to come by - but a hill or other building / structure that is 20' can provide the height.

The first place I would go would be the local telephone and electrical utility companies. They would have poles and might be able to make suggestions for the application. I suspect that power engineers routinely construct supports for transformers and switchgear that heavy.

Are you quite sure about the 2700 lbs btw?

I would also suggest that the city may be somewhat thoughtless if they simply say "it has to be metal."

Unless the correct engineering is done, a metal support is just as likely to fail as a wood one. And the correct engineering could be done for a wood structure as easily as a metal one.

One point you also need to consider is that you will have to hire riggers with a crane to place this article on the top of the support structure.

Old irrigation pipe.

Kidding. He thinks he's kidding.

I think there is some oil production in Arizona, You might try one of the oil companies to see if you could scrounge a bit of surface casing pipe. I think its about 13 5/8 inches dia.They usually have to cut off some to suit the depth of the surface hole so you might be able to convinve them that it would be a good bit of local public relations. They could even puyt a plack on it saying that they had sponsored it.

Rather than a pole..Id suggest a tripod.

Rule #35 "That which does not kill you, has made a huge tactical error"

Others have made good suggestions (water and oil drilling companies). You might try the utility (APS). I am sure they use metal poles in some of their construction. Ask the right person, and you might get one donated.

Absolutely. 2700 lbs is about a nissan sentra, right?

That's a piece of hardware floating in the sky.

Even if he cannot manage to find somebody to install the poles at an angle to make a tetrahedron, three of them with crossbars and braces would be a lot better than just one support.

Basically a super-huge version of a three-sided antenna mast, with the braces on the side to make each side into a truss.

How about a 6" square 40' tall light pole (steel)? $100....you haul!

Steel reinforced concrete block.. Can be "assembled" on site.. Just need to get a crane to the site to lift the siren up there..

Btw.. 2700 lbs sounds like a HUGE siren..

I believe it was in Oregon or Washington, there was a big flap about cutting down trees and endangering the spotted owl nesting sites. Then they found some nested in an abandoned K Mart sign.

Be sure to put some screening on it so they can't nest in there. Or some low flying spotted crested Dolly Parton titmouse can't fly in there and hurt themselves.

Ouch!

A Chrysler Victory Siren

is around 5000 lbs (including the hemi engine powering it). 2700 lbs is by no means puny! Not something you put on a "pole"...

My 2 door soft top geo tracker is 2600#. That must be a big honker! Pat

I have an old city light pole in my back yard you can have. However I'm a far distance from you as I live in Washington state.
