[TowerTalk] [Bulk] Climbing mast

[Grant Saviers]

I made them myself, using a 6"x 10"x 3/16" steel plate drilled top and 
bottom for two mast sized u-bolts, then 1/2 square steel bar bent into 
an almost closed squared off "C".  The long straight part of the "C" is 
18" long and welded to the bottom of the plate and the points to the top 
of the plate.  Thus, it is impossible to slip off the ends of the steps 
and the 1/2 square bar has good grip on the boot.  No worries about moss 
or slime on the step.  With the u-bolts about 8" apart, the step has no 
wobble.  The closed shape is a convenient tie point for fall protection 
since a carabiner can't slip off.  Since the points of the "C" are 
returned to the plate and welded, it is just about impossible for a 
climber to bend the step.

Either a press or torch is used to bend the bar and after welding they 
got hot dip galvanized.  Paul at custommetalworks.com told me this is 
his design and his climbers were happy with what I made when they 
climbed my 3" mast.   I don't see them on his web page, but they may be 
available.
