[TowerTalk] LOOKING FOR A USED CRANK UP SELF SUPPORTINGTUBULARTOWER

[K6XN]

Jim

I recommend you contact US Tower directly or check their website. The bolts
they sent me last year for another MA-770 installation were straight bolts
and only 1 inch by 27 inches rather than the 1 inch by 36 inch bolts already
installed at the Nevada site.

Thanks and 73, Ted, K6XN

Doesn't US Tower require J-bolts, rather than straight bolts?

location in Nevada for contesting. I already have in place 10  cubic yards
of steel reinforced concrete with 1 inch diameter by 36 inch  long anchor
bolts imbedded in the concrete. The anchor bolts are spaced 9  inches apart
which will accommodate a US Tower tubular tower Model MA-770  with the
MARB-770 free standing Rotor Base and the early Tristao 70 +/-  foot crank
up tubular towers.

Hiya, Ted --
 
    I wouldn't worry about the bolt pattern. The  existing bolts can be
chopped off with a hand grinder and then you can  rent a drill with a
concrete bit or a hammer drill to drill new holes.  Epoxy in the new anchor
bolts and you're good to go. Construction guys do this  all the time and it
works great. When you're done, the epoxy is typically  stronger than the
concrete.
