[TowerTalk] Alliance HD-73 Rotator U-Bolt

[john at kk9a.com]

McMaster-Carr has a great selection of U-Bolts but I doubt that you  
will find one that is 1/4 diameter with a 3" C-C.  %/16 would be a  
better bolt choice if it could be made to fit the clamp.

Greetings,

                 Last summer someone in the club decided tighter is  
better and mangled the threads on the U-Bolt that is part of the mast  
clamp on the club's Alliance HD-73 rotator. It is Alliance part number  
X-19434-B.

An email to Norm's got a message back saying they will only sell the  
whole clamp assembly.

A trip to several hardware stores has not turned up anything that fits.

I am not a machinist, but my measurements say the holes it goes  
through are at most ¼ inch in diameter. They are 3 inches apart center  
to center.

I would love to find something the same original shape, but I think a  
standard U-Bolt shape should work.

Anyone know where to get something that works?


Thanks and 73,
