[TowerTalk] Aluminum tubing needed

[john at kk9a.com]

The closest standard in Ø3 6061 drawn tubing has 16ga (.062) wall. Consider
upgrading the boom to a larger wall or turning down the coupler to fit the
replacement tubing. All of my homebrew HF beams that use a 3" boom have a
1/8 wall.

I am looking for a short piece of aluminum tubing with which to repair the
boom on a home-made copy of a KLM yagi antenna.

I need a 39" long piece of 3" outside diameter tubing with a 0.055" wall
thickness. I cannot seem to find this size listed in any of the steel &
aluminum catalogs, so I am thinking that this is a non-standard size and
that KLM had it manufactured for them, as Telrex used to have done.

I am hoping that someone has an old piece of KLM boom material and that they
can fix me up with a piece of this tubing. Thanks for any help with this!
