[TowerTalk] Aluminium tube

[TexasRF at aol.com]

John, a broken boom will not be perfectly round at the fracture point. You  
may well need the extra space the .048 material will provide. 
 
I suggest you use the available .048" material, cut a couple of slots  in 
the ends and secure with small hose clamps.
 
The increased diameter will be stronger than the original design.

Hello  all

A friend has asked if I can mend his 23cms aerial from M Squared.  It was
dropped and the boom has fractured just beyond the joiner, which is  a 7/8"
diameter sleeve 6 inches long.

What I hope to do is to  provide a longer sleeve, which will go over the
original join and the  fracture.

The material needed is a 10 to 12 inch length of 7/8" OD  aluminium tube,
with a wall thickness of 0.058". The wall thickness is  important, so that 
it
slides snugly over the boom. The nearest I can get  here is 0.048" which 
will
be a sloppy fit.

I can see that DX  Engineering has exactly what I want, but there's a $20
minimum order and  $33 carriage to the UK. So, I know it's a long shot, but
does anyone here  have a suitable offcut ? I can pay with Paypal.

Many thanks

John  G4ZTR
