[Rhodes22-list] Crane question

[Todd Tavares]

Allyn,

The .125 wall thickness aluminum tubes should be adequate if the diameter
is large enough > 1.5 or so.
Raising from the stern raised cradle using the GB mast raising system pole
is much easier and less risky than raising from the bow using the boom as
the gin pole.
There are plenty of pictures of the GB mast raising system on the web and
this list if you have the skill and desire to make a clone for yourself.
The GB system uses a winch with friction brake, mounted to the top of the
capitol mounted gin/crane pole. I use the trailer winch.
I can post some pics if I can dig them up.
