[TowerTalk] Long Tangent U Bolts

[Ken K6MR]

You can get a “Universal Clamp Set” from the commercial suppliers.  It will clamp two parallel pipes of various sizes (up to 3” or so I think) together.  Try Tessco or Talley, anyone who sells commercial  tower hardware.

I was thinking LONG U-bolts Jim, like to fasten two 2 inch boom pieces
together or other such odd needs plus possibly a saddle and rigid plate. I
see DX Eng sells the SS or Alum saddles and a rigid plate in a set, but I
just need 1/2 of the saddle set plus the rigid plate. Also need to take into
account the fastening hardware.  That ends up a LONG U bolt. I looked at DX
Eng data on the U bolts and see the ID, thread size and length but nothing
on the C length, the OA length from the inside of the curve to the end of
the bolt thread (unless I missed something).

Has anyone used U-Bolt-It in Houston to fabricate longer U bolts than
available in standard sizes? If so were they able to deal with small
quantities at a reasonable price (like 2 to 4 pieces)?

##  what size  bolt..and how long does it have to be ?      The SS  U bolts
I bought from DX eng  have the longest threads I have ever seen on any U
bolt.   They provide for bucket loads of
excess thread.   They also come in both  .3125 and also .375 sizes.  You can
easily have enough thread to go through say a .75 inch thick AL plate..with
plenty left over for the nut etc.
