[TowerTalk] 3" Boom Joints

[john at kk9a.com]

For splices to 3 inch x 1/8 wall boom, I use 2 1/2" Schedule 40 6061-T6
aluminum pipe.  The O.D. is 2.875 and the I.D. is 2.469.  Then I have the
O.D. machined to 2.735 - 2.740.

I am planning the construction of 2 yagis, and I was wondering about "of the
shelf" material to join 3" aluminum tube sections for very long booms.

Any suggestions would be appreciated.
