I've got some large diameter galvanised water pipe here (4" and 3" NB) and thought I'd make a telescopic mast like the Wilson. Can a Wilson owner tell me are the tubes in the Wilson mast all circular, and if so, how is the inner tube prevented from rotating in the outer tube. Is there a keyway of sorts. I'd be pleased to hear from you. 73 Mike ZL1BNB |
