yup!!.... it certainly saves wear and tear on thee old finga's
I did infact post that vid in the ever so big and growing 'micro coil' thread prob about two month's back but i dont think it had much interest apart from from a nice guy that post's often over there called 'MacTechVpr'
He explained to me that he had done some research and read things from others doing research and testing and to get a perfect tensioned coil that has wraps 'welded' to each other plus 'wire memory' takes about 100 pounds of newton force
Hence the reason some are building coil wrapping tensioning mech gadgets to perfect it
Most people can keep 100 pounds of newton force on the wire by hand/arm force alone but to keep that tension constant to get the wire wrapped perfectly is quite hard to do, i dont think its impossible as i have a technique of wrapping 26g by hand with only a mandrel that after its been wrapped looks like the outer edge of the wire has been flattened but its
not very kind to my hands or circulation
How far do you want to take it and how much difference do you actually notice
Me personally, i dont really see any dif in supertight tensioned wrapped coil's to coils wrapped either freehand or by the method in the vid but that doesnt mean there is or isnt a difference
Another thing Mr MacTechVpr said was that the vid method is 'Forming'... i agree with him to a certain extent but it also depends on if you just 'Form Tension' the same coil once or twice etc as the second time takes more pressure to form
R41 though acts totally dif to kanthal and nichrome and has a lot of spring and memory, is very hard to form But use the vid method and you get very tight wraps that you cant see through
hope that helps anyone and if you anyone wants to add or comment your welcome
