Glad to hear your experience David...by the way, 1/4" solid steel wire is
available here...it is cheaper than 1/4" EHS galvanized wire and sometimes
galvanized is not available...David, how do you fix the solid steel
wire???...using clamps or any other technic ???...any tips are welcome.
I have "TONS" of egg insulators, maybe if i "switch" to 1/4" solid steel
wire I can add egg insulators.
I will solve one problem but i will introduce another...corrosion will
attack the solid steel wire faster than galvanized...Imperfect WORLD...hi,
hi...
Non conductive materials like Philistran or Dacron are NOT AVAILABLE here.
Thanks,
73....Douglas, CO8DM
