[TowerTalk] how to install the tower base over a sloping roof???

[Douglas Ruz (CO8DM)]

GM all,

Thanks for all replys and ideas.

I forgot something...my base plate is not finished yet...i have an 1/4" 
steel plate and 3 short tubes that fix ok inside the first tower section.

I have an idea that i would like share with all of you...if first i fix the 
steel plate to the roof (using bolts decribed by Perry, K4PWO in the message 
below) then i can weld "in situ" the 3 short tubes and i can correct the 
sloping without add nuts or washers below the steel plate.

I will use 2 set of 3 guy wires at 12 and 24 ft high.

Thanks,

73....Douglas, CO8DM
