Yes, they "wobulate" .. matter of fact, all the tall crank-ups I have worked
with do ... some more than others, but never seen a failure because of that.

Subject: [TowerTalk] LM-470 question
Greetings all,
I have an LM-470 from an SK estate that I've put back up. Last night I did
the first up/down test after transport and was surprised to see the top
section "wiggle" a bit when it got to full extension. Is this normal? I
expect some amount of play in it, but when you see the top of your tower
move a few inches sideways when it's 70' up, it's a little disconcerting
when you're planning to put a 40' beam up there... <g>.
Anybody have experience with these beasts that suggests whether this is
normal or not?
Cheers,
Rob Salsgiver - NR3O
