Warning note :  not being in a "showing off mode" when writing bout knots I shall not use
academic training and dispense with boasting about BIBLIOGRAPHY ( that is all
publications one can find on the subject) and REFERENCES ( that is only the publications
that were actually read.Many authors don't make the difference and put as reference some
of a bibliography they never laid they eyes upon )

Added 2010 May 1st : correction made in  the three documents for ROW : a slight shift
in a part of the second illustration made it misleading

Added 2009 January 8th :
An HP48 program to compute the crossings by half-period and to built a slide-rule
( Schaake & Turner's idea )  for inter-bight coded ( row for mandrel ; column for
cylinder ) knot made on a THK shadow ( cordage route )

The user documentation must be read and understood before
downloading the EMU48 with the SCHR ( for SCHAAKE-ROW ) program ( and of
course the preceding one also.
 

SCHR.HP file      SUPERSEDED
you can also download the SCHK.HP which does the the Turk's-Head and
parallel-bight coded knot
( column for mandrel ; row for cylinder )
As in my experience this type of "instructions" is much in demand here are

THE BRAINLESS RECIPE FOR USERS

HOW TO USE THE SLIDE RULE


PLEASE ! just for this one : use my email ( bottom of page) to give your critics
positive & negative and signal BUGS

WARNING : ALWAYS USE THE LATEST VERSION ( look at the time stamp for
the .HP files in 'My Programs' in the EMU48

 
_______________



COMPLEMENTARY PERIODIC AND PERIODIC BIGHT COMPLETE
ALGORITHM
Go there if you have problems with installing and working the EMU48

Added 2009 January 11th :

For you to use as you see fit to obtain the coding in half-periods.
BALG.HP file     SUPERSEDED

BEWARE : this is the algorithm written as it should ( Schaake & Turner ) and *not* in the
fashion that disfigured it. There is a '0' for the concerned bight rim empty of crossing
that is there to disambiguate where you are , this is absolutely impossible with the
amputated version by HALL.   ( for a full explanation see my THK pages )

Either you download again the full complement of EMU48 folder or you download only
the BALG.HP file that is in My Programs in the EMU48  folder ( see EMU 48
STARTER
 Help just in the topic just above ) and you 'loaded' it yourself in the emulator.

Here is the BALG USER'S TIPS.  that is also  sufficient to do the coding with only 3 tools :
 brain engaged, paper and pencil.


ANOTHER PROGRAM TO USE HAND IN HAND WITH BALG
THE BIHP program = BIHP USER's TIPS

 _______________



AUTOMATED COMPUTATION OF ENLARGEMENT OF THK ( my restricted
view of them ) : you just enter L and B that all in the EMU48
Go there if you have problems with installing and working the EMU48


Added 2009 August 29th :  results can be mistaken if LEAD and/or BIGHT is LESS
THAN 2

Another version ( slower ) is available on asking for  LEAD and / or BIGHT being at least
ONE  ( PGR3 and PGR4 doing what respectively PGR and PGR2 are doing )


Added 2009 January 12th :
read what is in the three topics just above.


This is for the HP48GX EMULATOR EMU48 : ENLAR.HP     SUPERSEDED
Either you download again the full complement of the EMU48 folder or just ENLA.HP
taken from the folder MyPrograms and you load it yourself if you know how in the
emulator. Your choice


With those equations taken from page 108 of issue N° 6 of The Braider the results I  got
were consistently false when compared to real life experience with a large set of knots or
diagrams.

With that correction applied the results were seen as in accord with experience.

This * does **not**  * imply in any way that the equations in The Braider are mistaken, not
at all, only it is to allow you to understand from where comes the discrepancy between
equations you may know and those I use for my purpose.


Added 2009 January 14th :

Enhancement added  see ENLARG USER'S TIPS :
you can now get the "root" THK and the enlargement that was used to make the THK you
are analysing. Download the new ENLAR.HP or the whole of the new EMU48.  ( can be
lengthy - 20 mn  for the four nested search loops- on a real HP48 for a 24L 17B THK
coming from  10L 7B via E1-- Less than 14 seconds with the
EMU48 )

COMPLEMENTARY PERIODIC AND PERIODIC BIGHT COMPLETE
ALGORITHM
Go there if you have problems with installing and working the EMU48

Added 2009 January 16th :

For you to use as you see fit to obtain the coding in half-periods.
JOAT.HP file     SUPERSEDED 

Its is a JACK OF ALL TRADES program that does the very tricky
NEITHER row NOR column coded knots on a THK shadow

but also

- ROW coded
- COLUMN code
- Row AND Column coded

Here is the JOAT user's tips PDF


ALWAYS make sure you are using the latest version of any file : compare the
date of the
files in the My Programs folder in the emulator on your PC with the
ones on line for
download.

ANOTHER PROGRAM :
Go there if you have problems with installing and working the EMU48

Added 2009 January 21st :

For you to use as you see fit to obtain the coding in half-periods.
BINX.HP file       SUPERSEDED 
or YAJOAT Yet Another JOAT by other computational procedures and
giving "staged" results that can be "exploited" in a manual procedure for
exceptionally difficult knots on a THK shadow.

Here is the BINX user's tips PDF

ANOTHER PROGRAM : a LARGE one : DOING STANDARD
HERRINGBONE PINEAPPLE  aka PINEAPPLE for short ( the real type of
PINEAPPLE )

Will need users accepting to set themselves in "Brain-Enabled-Mode".

 PINALP USER'S TIPS

Coming PINALP.HP and PINALP2 to be put in the MyPrograms folder in the
EMU48 download.  ( available for the asking only : use email at the bottom of each
page ! )

Go there if you have problems with installing and working the EMU48


_______________


ANOTHER PROGRAM :


Added 2009 February 4th :
LONG KNOTS COLUMN-CODED  ( available for the asking only : use email at
the bottom of each page ! )

In order to use the BIGHT ALGORITHM method for those LOOOONG knots such as
135 L 8 B. Rather than a program in itself it is the explanation on how to proceed ( using
other PGR already made available )

_______________


ANOTHER PROGRAM : PIBU
stands for PIneapple BUilder and tester.

Added 2009 February 4th

PIBU.HP      
( available for the asking only : use email at the bottom of each page ! )

Wait a minute Dear Doug , you will get it in due time , post haste from little me )

PIBU USER's TIPS

This will help you built and test the possibility of making such and such Standard
Herringbone Pineapple Knots to your own specification without being the slave of the
very few examples ( trodden upon and upon and upon again and again ! ) available
in books.
It will also put some mistaken idea "straight" all thanks to SCHAAKE & TURNER.


_______________

 

NOT
ANOTHER PROGRAM for HP48GX BUT FOR PAPER AND PENCIL
USE :
SPECIAL ALGORITHM FOR LONG COLUMN-CODED STANDARD KNOTS
MADE ON A THK SHADOW.

This is NOT for those to whom apply this quote from SCHAAKE :

“We have remarked earlier that braiding a knot by means of its weaving-pattern is not a
recommendable method, for the reasons quoted. However, there will always be braiders
who have no desire to produce original or varied work, some of whom will swear by the
 “weaving-pattern” method of braiding. Needless to say, these braiders will never make the
grade of braiding-artisan.”


Weaving-braiding : braiding by laying a H-P that is immediately adjacent to the preceding
one ( of same orientation odd with odd ; even with even ). That can happen ONLY if 
Lmod B = 1 
or if 
Lmod B = B - 1

LONG COLUMN-CODED STANDARD KNOTS

A tutorial for paper & pencil writing of BIGHT ALGORITHM and HALF-PERIOD
CODE FOR (true) PINEAPPLE KNOTS.

_______________


BIGHT ALGORITHM of  MULTI-STRAND KNOTS MADE ON A THK
CORDAGE RUN
(shadow)  erroneously called THK by too many people (number
of strands needed being the GCD of L and B)

STRICTLY PAPER AND PENCIL, NO DIGITAL PROGRAMMING.

Here is the 20 pages or so PDF I wrote using Schaake method as he exposed it in
THE BRAIDER.

The extract I give here separately contain the essential instructions ( but no worked
examples).
I deliberately rendered some passages very faint as my goal is not to furnish free access
to THE BRAIDER itself.

My goal is but to motivate people to buy for peanuts (cost of a CD plus postage) the CD
with the whole collection of some 60  issues (some 1600 pages - A printed version exist
but is of course much more costly in price and postage ) of  
THE BRAIDER
from Dr John TURNER

THIS IS A BARGAIN  YOU SHOULD NOT MISS EVEN IF ONLY TO HAVE
THE BRAIDER
 AVAILABLE FOR FUTURE NEED WHEN YOU WILL REALIZE ITS VALUE
- HOPEFULLY NOT TOO LATE - .

ANOTHER EMULATOR  for HP48GX BASED ON " MESS  "

another HP 48 GX emulator offered by Antoine MINE
This emulator is making use of MESS ( Multi Emulator Super System )
You can get WINDOWS version of MESS but also MAC and LINUX at this link

I have no personal experience with it as I find EMU 48 simple and easy to use and a
faithful copy of my HP 48 GX. Still some may prefer this one .

_______________


ANOTHER PROGRAM : HER3
stands for HERringbone Knots.

Added 2009 November 18th

HER3  
( program download available for the asking only : use email at the bottom of each)
 
USER's TIPS  will be made available here in a short delay
USER's TIPS now available



Do not be part of the multitude that cannot even make the difference between
HERRINGBONE knots
HERRINGBONE PINEAPPLE knots
HERRINGBONE Herringbone PINEAPPLE
NO nested bight, all are on the same unique rim  NESTED bights
ALL the component THK have the same formulation L & B wise 2 SET of component THK ( one can be empty ) 2L of difference between the 2 SET


_______________

ANOTHER PROGRAM : TOTU

Added 2009 November 18th

stands for TOTal Use as with it you can get the coding of each half-period for
ANY single strand knot following the Turk's head cordage route be it
ROW coded, or COLUMN coded, or Row AND Column coded or NEITHER Row
NOR Column coded.

Having exercised my brain again on the HP48 for HER3 I realize that it would be nice to
"collapse" many things I learned from SCHAAKE x TURNER in one
program of my conception making the whole work..

Of course this program is slower that the specialized program but it can do any knot
you care to do on a a THK cordage route.

EXCEL WORKSHEETS ===TRANSLATION OF HP48GX PROGRAMS

Added 2010 May 14th

Nautile's EXCEL Worksheet
a working Schaake's slide-rule for ROW-coded knots made on a turk's head shadow.

For explanations better see the .PDF user's tips made for the HP48GX programs in
this Publications_3 page  up above near the top

THE BRAINLESS RECIPE FOR USERS

HOW TO USE THE SLIDE RULE



There is also a translation to VBA Excel of my H48GX program for ENLARGEMENT
in  Publications_5
 
Added 2010 May 18th
Nautile's EXCEL Worksheet for Row AND Column-coded ( that is THK ) and for
COLumn-Coded Regular Knot (e.g = Gaucho, HeadHunter, Samuel's, Fan, Aztec-Fan)
Read the .pdf made for the HP48GX program and my Turkshead pages on using
SCHAAKE's BIGHT SCHEME to find the code in each Half-Period of such knots.

Added 2010 May 24th
Nautile's EXCEL Worksheet  which is a Excel  VBA translation of the HP48GX program called PIBU ( for PIneappl BUilder )
If your knot does not comply with that then YOU ARE NOT DOING A REAL
PINEAPPLE ( StandardHerringbone-Pineapple Knot )

Added 2010 May 24th
Nautile's EXCEL Worksheet  which is a Excel  VBA translation of the HP48GX program
called TOTU that can do ANY TYPE OF CODING = Row 1 COLumn-code,
Row-Coded, Column-Coded, NEITHER Row NOR Column-coded.


Added 2010 May 24th
The following two EXCEL Worksheets are for people who do not make a confusion
(included among those making confusion countless website and some Authors of well  
known books ):
* between REAL PINEAPPLE and any other THK assemblies with nested-bight , 
* between HERRINGBONE-PINEAPPLE knots and HERRINGBONE knots
* between those and knots Herringbone PATTERNED but in fact Neither
Herringbone-Pineapple K.  Nor Herringbone .
Simple enough = if your knot does not comply with one of those programs then is is NOT
the type of knot  your imagine it is.
Those programs comply strictly with Schaake definitions and equations and were extensively
tested with ALL the examples provided by Schaake.

For both Worksheet you will be better of with reading the HP48GX User's tips and ALL
the pages in this site relating to those 2 sort of knots.

Any one nor particularly gifted can make a Pineapple but not anyone can make a
Herringbone K with more than 3-PASS and that is probably why never HERRINGBONE
K.  with more than 2-PASS were published before Schaake research and the "secret" being unearthed.

Added 2010 May 24th
Nautile's EXCEL Worksheet  which is a Excel  VBA translation of the HP48GX program
PINAPL2.   ( it will allow only one PASS  at the same time and you will be exposed to
botching the Bight Rim entries if you do not know perfectly the HERRINGBONE
PINEAPPLE knots.
This one will be better when used with PINEAPPLE BUILDER : PIBU
Read this documentation if you really want this worksheet to be useful to you.

BUT.... THIS Worksheet does the WHOLE knot at once and  IS LOCKED on the deep
structure of the HERRINGBONE-PINEAPPLE = it can only produce REAL Herringbone
Pineapple Knots.
