wilson, I can certainly understand why you might think that but you're wrong. I designed this thing to be universal and not specific to any wire or wrapping diameter and there is no maybe or perhaps about it, it in fact works awesome. what I did may look very simple and amateurish but believe it or not, THAT was the biggest challenge here, designing and building in such a way that requires no tools and no skills, dead simple to make and very little money yet works perfect and is still pretty fool proof. I didn't build this for me, I built it for you guys... I have a mill and a lathe and plasma cutters and tig welders and trust me, I can build a very elaborate thing here if I wanted to, but my goal wasn't that, it was to design and share something so simple that anyone can do it.
I only showed one pair of $2 pliers one one pink eraser but I haven't showed all the R&D behind the scenes, I didn't just go buy one pair of $2 pliers I bought a bunch and I bought a bunch of different erasers and other rubber items to compare which would work best. I played with many ways to do this, but in the end I chose these nippers because they were the best way to share this here... I also built one with a pair of vice grips and one with a linemans pliers and both work great too, but require notching of the jaws... I didn't want this to be something limited to only those who are tinkerers and I didn't want that the end user would need to have a dremel or a drill or anything really, my goal was to try and design something that any average non technical person with no tools could still go out and get everything needed for this and put it together in one afternoon for like maybe $30 or so even if they have no technical ability, I designed it so even a child could do it and I did that so it would be useful to as many as possible. the only tools needed to build my whole setup is a razor blade and a small flat file. you will also need any ole pair of pliers to make the winding jig, that's it...
it looks very simple but the simplicity of this thing was really the biggest challenge here. as far as being universal, this one simple clamp design will do anything from 1.4mm up to 3.1mm and will do anything from 32ga. up to 22ga. which is the heaviest wire I have to test with, and it will do dual parallels no problem, I've only tested dual par's down to 2mm and down to 27ga but it works perfect at 2mm and 2.4mm, haven't tried dp's at 3.1mm but I'm confident it would work too. I'm not going to say that this will work with anything you could possibly throw at it but it will work for almost anything you can throw at it and it will def work very well for most common builds, anything from 1.4 to 3.1mm ID and anything from 22ga to 32ga. at least. it may work beyond these parameters too but so far this is all the testing I have done. perhaps if you are always wrapping heavy wire at 3mm you will stretch the rubber eraser enough that it would be loose once you go back to say 1.4mm, I haven't seen this in my testing but it's not impossible with enough use that might be the case, but even so, for like $3 each you could build a few of these and use one for larger heavy builds and another for light thin builds.. honestly I've gone back and forth from one extreme to the other with no problems but then again I haven't been using it for 6 months or a year yet at this point so I can't say for sure how durable long term it may be, but it's so cheap and easy that even if I had to make a new one every 6 months or just build like 10 at the same time, still well worth it to me. the only real expense here is the piece of leather, but for like $15 you can get enough leather to build over 50 of these
here is 22ga at 2mm and 3.1mm
I really don't want to come here and say this is the most awesome thing to come along for microcoils since the dark zero jig, I'd rather have others who try this come here and say that for me

I have built many coils and I have spent a whole lot of time and effort to try and build the perfect coil. don't know if you've seen my motorized tension winder but man it worked great. I'm telling you though that this little $3 gizmo is even better, better in that it is just as effective and even more universal in that it can do dual par's with ease AND it doesn't take a whole machine shop to build it. it's just about as foolproof as I can possibly get to and I promise that after you use this you're going to laugh at all the other more complicated and bulky methods before it. I will most likely never touch my motorized wrapper again because it can't do anything that this simple setup can't do and this simple setup can do things that the others just can't.
I hate to say this because I really don't like tooting my own horn but honestly I believe that what I am giving you guys here is nothing short of amazing and it will out and out kill everything else before it. I can certainly understand how this isn't obvious to anyone until you actually try it though...I want to keep this as an open source project and share this thing freely with you guys. I think once I start a tutorial thread and others start doing this, then it will become much more obvious as to just how amazing and awesome this thing is. I'm sending a setup to russ today and I'll send a setup to mac in a few days too. wilson I know you would have no problem building what I've shown from just the pics I've posted so far. I really wish you would try this and see for yourself just how much tension or compression you can create here. the only learning curve is determining how tightly to squeeze the handles and learning how to set the initial wrap with a backwards tilted bias. another thing I haven't shown here yet is how awesome this same exact setup can create perfectly spaced wraps too, if you change the tilt bias angle you can change the pitch of the wrap and create perfect spaced coils to, all on the same smooth rod that you make tight micro's with. if I had the time and energy I might have thought to build these and sell rather than giving away he formula for free as an open source project but I don't have the time or energy for that so the best I can do to bring this to the masses is to design it dead simple and keep it open source, my way of giving back to the community that has helped me so much in the past... I'm anxious to see these in others hands and hear what others think but I'm pretty confident that this is a killer recipe that most will love
