Note the nature of the cover braid It is made up of
strands with either one two or three ends By inspec
tion you can see half the strands revolve to the right X

around the rope and half revolve to the left Mark 3
Beginning at R and working toward the taped end of
the cover count eight 8 consecutive strands single or
pairs which revolve to the right or left Mark the eighth
8th strand This is point T Make point T go completely
around the cover Starting at T and working toward the
taped cover end count and mark every fifth 5th right and left strand until you reach the end of
the taped cover For those ropes with a 20 strand cover count and mark the fifth 5th right and
left strand From that mark count to the fourth 4th right and left strand Proceed in this manner

reinserting core into cover
From X on the cover measure approximately onethird 13 a tubular fid length
toward the slip knot on the rope and mark this as Z
You are now ready to put the core back into the cover from T to Z Insert the fid
at T jam the taped core end tightly into the end of the fid With the pusher push
the fid and core through the cover tunnel past X and through the cover at Z
When pushing the fid past X to Z make sure the fid does not catch any internal
core strands
note Depending on the eye size a fid may
not be long enough to reach from T to Z in one Insert core into

9 burying the exposed core
Hold the rope at the slipknot and with the other hand milk the cover toward the splice
gently at first them more firmly The cover will slide over Mark 3 Mark 2 and crossover
T up to R it may be necessary to occasionally smooth out eye during milking to prevent
reduced volume tail catching in the throat of the splice
If bunching occurs at the crossover preventing full burying smooth cover from T to X
Grasp crossover at T with one hand and then firmly smooth cover slack female side
of eye with the other hand toward the throat X
Repeat as necessary until bunching disappears
Continue milking until all cover slack between the Beginining at slipknot milk cover by

Mark 2
Bury to Mark R
10 TIP BEFORE b u r y i n g t h e c o r e
A Anchor the loop of the slipknot by tying it to a stationary object before starting to
bury You can then use both hands and the weight of your body to more easily bury
the cover over the core and crossover see Figure 1 and Figure 2
B Holding the crossover tightly milk all the excess cover from R to X
Flex and loosen the rope at the crossover point during the final burying process
Hammering the cover at X will help loosen the strands
With larger ropes it is helpful to securely anchor the slipknot attach a small line
to the braided core at the crossover and mechanically apply tension with either a
block and tackle capstan comealong or power winch
Tension will reduce the diameter of the core and
crossover for easier burying see Figure 2
