[TowerTalk] aluminum tube and pipe

[john at kk9a.com]

I am not sure what K5GAK's post was about, but McMaster Carr does specify T6
on some or all of their 6061-T6.  In the last couple of years, I have
purchased a lot of 6061-T6 DOM element tubing on eBay from Shapiro Metal.
6' long pieces are perfect for elements and they are easily shippable but I
would not use them for a boom.

I have been wary of ordering tubing from McMaster-carr or many of the other 
industrial places... if you look you will see that they don't specify that
the 
tubing is seamless, it is also not one of the common antenna tempers like t6
or 
t832.  they also only have 6' lengths listed unless longer stuff is
elsewhere.  
I prefer to go to a supplier like marmon-keystone:

eid=1&producttype=alumseamless#top

if you use their search app you can see that they break down tubing by
welded 
or seamless and its all t6.  they also have longer lengths, up to 24' I
think 
for aluminum... and at least they used to have free delivery at least in
some 
areas.  and they offer services like swaging, though I have never used them
for 
that.
