[TowerTalk] Fwd: Cutting 2" Heavy Wall Cr-Mo Mast Up on Tower

[Hans Hammarquist via TowerTalk]

Beside wonder how you are going to handle the cut-off piece, I would try a regular tube cutter. I am using one with carbide wheels and that seems to cut anything. Nothing but hand power is used.


Good luck but be careful.

Subject: [TowerTalk] Cutting 2" Heavy Wall Cr-Mo Mast Up on Tower


I have a 22 ft (2" OD) heavy duty Cr-Mo mast presently installed up on a 100
ft Rohn 45 tower.  It weighs 200+ pounds. I previously had a 4 el 20 meter
yagi stacked 12 ft.  above a 40 meter F12  yagi.  I just finished removing
both antennas for repairs and have decided not to reinstall the stack due to
the complexity of the installation.    I will be re-installing the 40 meter
yagi and some VHF antennas on this tower.  Consequently, I would like to
shorten the 22 ft mast by 10 ft.

 

I am looking for advice on the most efficient way to cut this very thick
high strength mast in place.  I would prefer to use battery-operated tools
such as a reciprocating saw(metal blade?) or a grinding tool (cutting
wheel?).  I can run 120 VAC (about 200 ft extension cord) up the tower if
needed.

 

What would be the optimum method for cutting this mast without excessive
tower time?  Thanks in advance for any responses.

 

Vic,  N2PP
