BIG FURLED LEADER FORMULA - Readers cast (Steve McGarthwaite) - Jan 30, 2012

[Steven McGarthwaite]

I created the Big Furled Leader Formula, after about 4 years
of working on the mathematical formula, and then I gave it to the
world for free use by all the people who make their own furled
leaders. So if you want to created a furled leader that has a loop
sequence of 13?-12?-11?. That gives you total thread count for
the combined thread segments sequence count would be 54-52-50-
48-46.

I use a two line method, I know most of you use the V shaped
layout that Kathy Scott shows on her DVD Video, but that gets a
little to complicated for my furling. One plus for my method is I
can always delete a peg position (eliminating the last segment) at
the tippet end for a more stout furled leader/tippet combo. I also
can start and end my loop wraps on the inside pegs for a different
loop sequence of 13-12?-11.

I have a lot more options in creation of my furled leader
designs. I mostly use Mercerized Cotton Thread for my furled
leaders, it is very strong thread, and not that expensive, available
lots of different colors and shades. Tag ends at the start and finish
are secured to the outside pegs. I can also secure them to the inside
pegs then it would be a 13-12?-11 sequence lot of other options
using the two run system.

I furl each side separately reducing the board length by 10%
for the left and right runs tacking the small ends to the board. I
then transfer the left run on top of the right run, to start the
unfurling process.

I add super glue to the loops at the top and bottom before I
do the shorb loop for final end connections. For the shorb loops I
use a Knit Picker (they have them at Jo Ann's Fabric and Michaels
they only cost about $2.

Example: 13?-12?-11? loop sequence
PERCENTAGES:

L0 & R0 = 0
L1 = 100% = 1.000
R1 = 1.000 x 0.55 x 54/52 = 0.571
L2 = 0.596 x 0.55 x 52/50 = 0.327
R2 = 0.358 x 0.55 x 50/48 = 0.187
L3/R3 = 0.217 x 0.55 x 48/46 = 0.107

Total Percentage 2.192

Finished Length 72 inches

10% of Finish Length added to formula for length lost in
furling process
72 inches + 7.2 inches = 79. 2inches (79 inches)
1.000/2.192 = L1/79.2 inches so L1 = 36.1 inches round
down to 36 inches.
PEG POSITIONS
L1 = 36.1 inches
R1 = 36.1 inches x 0.571 = 20.61 inches
L2 = 36.1 inches x 0.327 = 11.80 inches
R2 = 36.1 inches x 0.187 = 6.76 inches
C3 = 36.1 inches x 0.107 = 3.86 inches

Peg Positions
L & R Pegs 0"
L Peg 36"
R Peg 57"
L Peg 69"
R Peg 75"
C Peg 79"

You can use that Percentage Sequence for whatever length of
furled lead you wish that has that loop sequence. So half the work
is already done. You can use that percentage for different lengths
of finished furled leaders using that loop sequence/thread count

Once I have done the shorb loop, I like to dip my furled
leaders in some warmed lacquer, to help the thread to bind giving
the furled leader a backbone when casting.

I hang them up to dry, and before they are fully cured I use a
damp rag with some lacquer to smooth the exterior of the furled
leader to remove any lacquer build up….

I don't use spread sheets, I just do my two part calculations
Percentage base of the first length, and then add the 10% to the
desired length to compensate for the loss due to the furling
process. The finish furled leader should be within +/- 0.1 inch of the desired length…~Parnelli

Again my apoligies for the flawed articles, I have had too many pans in the fire this week...
