Tapered Aluminum polls for masts?

[Bruce46]

I was poking arrond the net and came across 6063 al. flag poles, would they be suitable for a CS 20? They are tapered full length. I believe that 6063 isn't quite as strong as 6061 so what would be the correct size.

We're going to need more info. Do you have a web site for them?

I was thinking of something like, http://www.americanflagstore.com/alflagpoles/25ftaluminum.htm  or http://www.excelsails.com/specialbudgetflagpoles.htm

If they're made the way I think they are, spun on a mandrel and the excess material is pushed up into the inside of the top section, then weight may be an issue. Strength will certainly be an issue.
