[TowerTalk] Cross Bar Suggestion

[RICHARD BOYD]

I think a lot of us use steel angle rather than pipe, because then you don't 
need a plate to mate the two pieces of pipe.

A steel angle 2-4' long, with a single "muffler clamp" (U-bolt with saddle, 
available in a range of sizes from auto supply stores) and a pulley at each 
end should do the trick.

Otherwise, if you use pipe you'll need the plate and four U-bolts.
