[TowerTalk] Screws used in Element Construction

[terry burge]

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.

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.
