[TowerTalk] Desired play (gap) between steel tube leg and sleeve onRohn 25

[N3XX]

I have found it difficult to put them together on the ground (laying 
parallel to the ground), but pretty easy when building them vertical.  I 
just rock the upper section a little, and they slide right in.
You might have a problem if they were bolted down too tight previously, and 
are no longer perfectly round.
