Hi Garry,
Using rivets and a hand rivet tool can work quite well and does a nice, clean
job. Maybe just use a slotted end with hose clam on each end tube for
adjustment. I have a 6 meter first director that a friend made for me on my
Steppir antenna and it really looks great.
thinking about rivets and other "permanent" assembly techniques (yes,
you can drill the rivets out)..what about using conductive epoxy to
assemble an antenna?
I am rebuilding a 17 meter beam I built about 35 years ago. At the time I used slots and
hose clamps where fastening element sections together but this time I am going to use
sheet metal screws. My tubing sizes will taper from 1.125" down to .625" in 5
sections per side.
I can't find any information on what size screws to use unless I'm just looking
over it. I have seen a recommendation to use hex head screws rather than typical
flat blade or phillips head due to possible damage to the screw head but nothing on
screw size. I also wonder if self tapping would be a better option than standard
sheet metal type.
#2 or #4?
You could also use hex socket cap screws - rather than a nut driver, you
use an Allen wrench
