just had a look here and like to mention two or three things:
1) great pics and nice presented - well done!
2) never thought twisting a string could be done way different then I'm used to do it
3) the screw - already mentioned above
4) "padding" - well, as I am not a native speaker, I may be wrong here but I am quite certain and think backed up by the anglo-saxon literatur of the last 150yrs, that you may have confused padding(*) with splicing and/or the splice?!
Your well done tutorial might be refered to by many people in the future, so the nomenclature is somehow crucical IMHO. I dont want to tell you what to do, but confusion in "string making" is already high enough, that there is no need to add on other point to it.
Someone out there to set me straight on this one?!?
* padding - as I always thought of it - is done by adding strands to the loops for reinforcment or to simply building up their diameter. The part of string in question is called splice.
