A 7-5-3 loop sequence is impossible to create.
Either the thread loop wraps are started on the inside post, or the outside posts. So they are either full loops or half loops, the middle loop is always a half loop.
So you can have a7?-5?-3? loop sequence, or 7?-5?-3 loop sequence, or 7-5?-? loop sequence, or 7-5?-3 loop sequence.
It make a big difference in the balance of the taper and performance of the furled leader.
You can even calculate the wieght of your finished furled leader.
Denier is the weight in grams, of 9000 meters of thread. So if you know the denier of your thread (3/0 =210 denier, 6/0 =140 denier, 8/0 =70 denier), and you know the tolal length of both loop sequence runs, you can calculate the weight of your finished furled leader.
Using a modified formula of David Ulmer’s “Big Leader Formula” for knotted leaders, I can calculate the peg positions for just about any loop sequence and length for any furled tapered leader.
The taper is constant, the reduction of weight per segment is uniform, and the finished length is accurate to less than a inch difference.
7?/5?/3? loop sequence
P1 = 100% or 1.0000
P2 = 1.0000 x 0.55 x 30/26 = 0.6346
P3 = 0.6346 x 0.55 x 26/22 = 0.4125
P4 = 0.4125 x 0.55 x 22/18 = 0.2773
P5 = 0.2773 x 0.55 x 18/14 = 0.1961
Total of the segments percentages = 2.5208
So 1.0000/2.5208 = L1/99 inches (90 inch + 9 inch for shrinkage during furling process)
so L1 = 1.000 x 99 inch/2.5208 = 39.2732 inch
(Left & Right Pegs 0 inch)
L1 = 39.2732 inch ( Left Peg 39 inch)
L2 = 0.6349 x 39.2732inch = 24.9346 inch (Right Peg 64inch)
L3 = 0.4125 x 39.2732 inch = 16.2002 inch (Left Peg 80 inch)
L4 = 0.2773 x 39.2732 inch = 10.8905 inch (Right Peg 91 inch)
L5 = 0.1961 x 39.2732 inch = 7.7015 inch (Left and Right Pegs 99 inch)
Reduce each run length by 9 inches, then combine the loop end at the butt end over a single, then loop both tag ends through a hook connected to a heavy weight and hang to allow the weight tag end loops to unwind, creating the furling process. Using AC glue secure both furled ends (leaving a small loop) for creating the finished loop construction using a knit picker!
I normally dip my furled leaders in varnish to seal all the thread strands and to bond them together (also gives the furled leader some stiffness that helps transmit the energy transfer of the cast).
Before the varnish on the surface become hard, I wipe down the furled leader with a clean cloth dampened with some varnish to smooth and seal any openings in the furled leader.
