>> Take a look at the picture of the tool next to a pencil for size
>> This tool was uniquely suited for one particular job while disassembling
>> ice and wind damaged 40m4lldd yagi. Out of all the tools in all my
>> tool boxes this one stood out for this one specific task.
>> Can you identify:
>> 1. What it's original purpose(s) were?
>> 2. What it would be used for in a 40m yagi disassembly?
>> Pictures of the 40m damage in progress are below... We had 3 ice storms
>> weeks, 2 of them were followed immediately by strong winds. Besides
>> to both 40m4lldd's there were several bent elements on 20m4dx yagis that
>> survived several years with 'normal' ice and wind. Something interesting
>> note is that the loading rods on the 40m4lldd's did not provide any
>> mechanical strength to the elements even though they look like they would
>> act as trusses. The elements all bent on the same side of the antennas
>> because the wind hit them from the side while the element was already
>> down under the ice load. The same mechanism damaged all 4 elements of
>> top fixed European 20m yagi that was sideways to the wind, while the
>> rotatable one above it only had 1 slightly bent element since it was
>> pointing into the NW wind at the time. The loading rods broke all on the
>> same side because the wind shifted while the elements were bent so one
>> of the loading section was stretched against the side of the element.
>> Tower is 180' of Rohn-55 with the 40m4lldd's on ring rotors at 70' and
>> 2/2 Top 40m with ice and wind
>> 2/2 Top 40m with ice, note how on the left side all 4 elements are bent
>> the sme place and the loading rods are below the element tubing.
>> 2/2 Top 40m with ice element closeup
>> 2/2 Bottom 40m with ice
>> 2/7 Top 40m with ice and wind, round 2 of the storms you can see the 1st
>> loading rod broke on the right element. Eventually all 4 elements ended
>> with 1 broken rod, all on the same side.
>> 2/7 Top 40m with ice and wind, slightly crooked elements.
>> 2/7 Top 40m broken loading rod closeup
>> Removal of the damaged antennas was done by XX-Towers on 3/7:
>> Rigging bottom 40m, tram line is cable coming down to left.
>> Bottom one coming down
>> Bottom one wide view
>> Closeup of broke loading rod end, its really not pulled out, the shorting
>> bar held and the rod broke. The ss saddle and eye arrangement on the
>> cable is my modification to prevent the philly from being cut on the side
>> the small holes it used to go through on the shorting block. M2 has
>> modified the design with a strain relief to prevent that on new ones.
>> Rigging the top 40m, tram line is hard to see but comes down between guy
>> wires toward bottom.
>> Rigging top, wide view.
>> Liftoff of top one.
>> Top one starting down
>> Interesting rigging, use ring rotor supports and boom brace to spread
>> to 4 points on boom.
>> Insurance has already paid off and I am awaiting delivery of a new 125mph
>> 40m4lldd for the top. For the bottom one I salvaged parts from the top
>> to make it whole and have purchased aluminum to beef it up similar to how
>> the 125mph elements are done. I also am waiting delivery of a 20m4dx to
>> used for parts to replace bent element sections on those antennas.
>> Of course I am writing this today because we are now getting
>> rain/rain/whatever out there and I figured I can wait a while to continue
