[TowerTalk] My first tower section is not plumb...

[Douglas Ruz (CO8DM)]

Thanks for all replys.

OK, first, I will build a Gin Pole...I think it is not a problem.

Second, seems that my verticality errors are "into" the tolerance range, so,
I think I can do some corrections before tighten the bolts...I put
some pressure in one of the temporary guys and make the 2nd section plumb.
In general the tower (only 2 sections now) is very stiff with "My temporary
guy ropes"...I climb to the top of the 20ft to attach the line with weight 
(plumb bob) in the center of the tower and I dont feel any movement.

My questions is:

Can I try to make the tower plumb without adding to much stress to tower
legs???

Thanks,

73....Douglas, CO8DM
