The TFE augmented pulling grease was found at McMasterCarr, not that
much more expensive as we used just less than one quart, and it sounded
like good insurance as we expected problems. It went easier than we
expected, so maybe it helped. Having folks available to keep the wires
clean and feed them straight without twist also helped a lot. Only one
wire was available spool fed.
All wires were pulled at once, I don't think any other way works for
this length. We did taper in the wires over about 3' and used woven
nylon flat pull tape and lots of grease periodically during the pull.
To prelube the Nycoil the pilot line pulled a bunched up plastic bag
with lots of grease on it when we pulled in the stronger pull tape .
I'd be tempted to use flex poly pipe (e.g. well or irrigation pipe) for
underground runs, if it can be tied or buried flat for the pull. Why
have joints?
b.t.w. the Wil-Burt rep suggested we feed the Nycoil into 70' of hard
conduit, 3 or 4", I don't remember. After we received the Nycoil, the
memory seemed so strong that I couldn't imagine pushing the Nycoil into
that conduit, or that it might turn the whole sheebang into a slinky!
We counted the turns around the mast of the old Nycoil and after the new
one was stretched out for the better part of a warm day, it's memory
returned as 15 of 19 turns, so we easily cranked in the missing 4
turns. This stuff is tough.
