Subject: Re: [TowerTalk] Shorty Forty Hose Clamp thread
My problem with the torque method is so you torque the clamp to specs and
yet you can still turn the smaller element inside the larger. So torquing
in this application in meaningless. You tighten the clamp until the smaller
tubing does not turn, let it cycle overnight, check and retighten if
necessary. My elements don't fall apart and my temperature swings are from
minus 40C to plus 35C. Real world or simple method.
BTW this is what I e-mailed to Billy:
Still waiting for your reply. You do have some answers don't you?
After not receiving a response to any of my questions, I managed to inspire
Billy to try and answer one, however with a condescending tone.

## If you tq to their MAX tq figures, the smaller tubing inside will not
spin, even if
you slop penetrox on it. Unless the yagi tips have to be adjustable, then
maybe use
SS hose clamps for the tips only. The rest of the yagi should be using 3 x
rivets
at each joint.
