Use staples (cheap, easy and reliable)

Made several of these. No problems so far in 20 years

Hi all...I have been thinking of ways to make Teflon Chimneys for GS-31 and
35B tubes from 1mm sheet...I am finishing off a 2 meter and a 70cm amplifier
at present and would like some opinions...

The simplest solution looks to me as making the Teflon tube and fastening
the join length with brass eylets perhaps one eylet per inch....

My concern is would the small eyelets be subject to RF heating and perhaps
burning the Teflon sheet at the join??

Thanks all....Bob..VK3ZL..
