first, it's not fixable.
the axle for the shoe isn't parallel with the pivoting foot.
try this:
use wire pulling lube instead of grease. less of a mess.
get the shoe and the foot lubed.
clamp in a piece of pipe, and instead of using a no dog,
put a short piece of strut strapped level.
bend a 45 bend. put a digital level on the strut and see how
much it rolls.
flip it over, and make a second bend.
set the strut level before bending.
it should roll the same way the same amount, giving you a
flat bend. the two bends should cancel out.
now, this PITA will give you hell every time you try to bend
multiple bends and kicks on one piece of pipe.
return it and get your money back.
over the years, i've started looking askance at greenlee products.
it seems they are just cashing out the equity on their name, making
stuff that isn't good, and charging the hell out of you for it.
i bought a 600' greenlee pull rope, and after the first pull, there were strands
separating the entire length of the rope, and that rope never hit 1,000# on
the strain gauge when i pulled that run. rolled it up, and back it went to the
wholesale house. bought a maxxis rope to replace it.
i honestly feel the brand isn't a good value any more.
