[Towertalk] Mast lowering/raising?

[djones449@cogeco.ca (David Jones)]

Hi All,
I know this material has been covered in the past.  In fact, I did have a
link at one point to a great example with pictures.  Any help or directions
to help would be appreciated.

Question...
Best way to lower and raise a mast on a tower?
For example...
a) to raise out of a rotor to swap it out
b) to lower it far enough to swap out a bearing on the tower top
c) to lower it, bolt on a 2m beam, then raise it and bolt on more antennae

Thanks
