I installed 40 feet of Rohn 25 today. Third and fourth
section (on top) don't sit properly on the lower sections.
Third section needs to come 1cm down to allow both bolts to
go in. First set of guy wires is installed on this section,
so it sits firmly, but without bolts. Fourth section moved
only to the upper hole of lower section, and is temporarily
secured by bolts but has to go about 5cm down to get second
set of bolts in (the lower hole of the fourth/top section is
aligned with a upper hole of the third section). There will
be another piece of Rohn 25 2,20 m long with a bearings and
mast on top and second set of guy wires. Plan to put
temporary guy wires on the top of the fourth section, before
last piece goes up. Since last piece is heavier (mast and
bearings) it might be lifted with a crane.

Any hints how to move sections down? Jumping moved it, but
not as much as expected.  Is it safe enough to continue with
last section??
Friend of mine, who was doing rigging, thinks that it's safe
enough.
If it goes up well, will test it as P3A next weekend. If
not, QRX till CW.
