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..
