[SML] proper batten clamping device for pipe-downs

[Loren Schreiber]

This old phart thinks the Mega-Coupler Pipe Adapter is an accident 
waiting to happen. I am not comfortable with a threaded pipe connection 
that depends on the threads for support, especially over my head. The 
set screw will damage the threads eventually, and I know that the same 
pipe will be threaded into the same coupler time after time. And any 
kind of dynamic situation--vibration or high-speed mechanized movement 
like, say, on a cruise ship, will work this loose in no time. 
Nope--don't like it at all. But that's just me. Regardless of the 
connection you ultimately use, I'd still drill a hole and run a safety 
cable through the tail-down and around the batten. Belt *and* suspenders :)
