M3 rod for microcoil - will this do? A little help please :)

[Cupcakesugars]

Hi! I'm pretty new to vaping, roughly 6ish months give or take. Well, the past month I've been flirting with coil builds, RBAs, yada yada (it's worth noting that I haven't been too successful, with the exception of ONE protank coil I rebuilt that's works pretty ok...I'm convinced my success was a fluke).

I keep reading about the "m3 screw trick" for microcoils. I still have yet to totally understand what it is and how you do it...

any my links to a clear and understandable tutorial?

Also, would this rod work? Seems like it would maybe be easier with something like this cause it's long so you'd have more surface to hold. Am I right with my thinking? If not, what exactly is an m3 screw?

thanks!!

I just use part of the stem of a landscaping/yard flag to wrap mine. I made a little ghetto jig and can just wrap the coil, slap it on the atty, pulse it and pinch it once or twice and it's good to go.
Look up Darkzero' s coil jig on YouTube and welcome to micro coil wrapping bliss

the idea behind the "rod" screw is to wind the wire in the grooves of the threads making the coil nice and uniform. Only issue I see with it is you have to unscrew the rod out of the coil....

I use these to make microcoils: http://www.walmart.com/ip/Stanley-H...gMethod=Recommendation:wm:RecentlyViewedItems

I use the 1.4 mm flat head to make 2.3 Ohm, 32 gauge, 7 wrap coils:


IMO, microcoils are easier to make and work better then the stock kanger. I've had one in a 3.5 ml mini hypertank clone for over 4 weeks with the same cotton wick and it just keeps going and going (of course the light MBV blueberry juice I vape helps).

An M3 screw is a machine thread screw (the kind of screw you put a nut on or screw into a threaded hole).

M= metric
3= diameter in mm

So yes, that rod would work the same as a screw. You should be able to find a M3 screw at lowe's, Home Depot or any hardware store that sells metric fasteners. You should have a choice of lengths, too. Just wrap the wire in the threads following the spiral they make, it comes out nice and evenly spaced. You will have to turn the screw to get the coil off (basically "unscrewing" the coil to get it off, just like you would a nut).

How'd you get it so perfect? Especially with the 32g wire!? I think that's considerably harder to manage. Wow I'm jealous

To get a tight coil it's really not that difficult. If you look at some of RipTrippers coiling videos on YouTube you'll see what I mean. There's a good one he did where he shows how to recoil a ProTank coil head. See the link below. He's a little bit country and kinda "over the top" but the methods he shows work well.

For me, I don't build a 'tight' microcoil but rather leave space between the wire coils, using a 4/40 machine thread bolt or an M3 (3mm bolt) work the best for a Protank's head area. I use brass bolts because it's easier to see the coil wrapped around the brass threads that way.
I then torch the coil while it's on the bolt to 'set' the wire. I use 30ga. A-1 Kanthal with a 5/6 wrap and get 1.2-1.3 ohm coils and cotton wicking. I fluff the cotton where it exits the coil head and I have had no need to use an extra flavor wick to prevent leaks or gurgles.

Good Luck and Have Fun!

Luck! That is probably the best one I've made so far.

I torch the wire prior to wrapping, then very slowly and carefully wrap as tight as possible, pinch with needle nose pliers and torch again. Most of the ones I make come out pretty close to perfect. The micro screwdrivers make it really easy to hold and wrap on. Plus I leave the coil on the screwdriver as I install it in the base. Keeps the coil in perfect alignment and height as I reset the rubber grommet and pin.

Here are three that I have waiting in the wings! As you can see they don't always come out perfect but they still fire evenly and work just as good, so don't sweat the small stuff!

I think the idea of the (2mm ?) screw is to wrap in the threads for a perfectly spaced coil. That works ok but I'd suggest trying a smaller diameter, tight wrapped coil (tight wrapped as in touching). I tend to like 1/16th (1.6 mm), but other sizes up or down from that work also.

A small allen key isn't too bad to wrap on as well. Angle the tip of the wire across the short end up to the long end and trap between thumb a finger then wrap away.

I drilled a 1/16th inch bit into a little block of wood and I wrap on that. It looks a little like the above picture, sans the screw.

It's a little pricey for me, but this is the best store bought contraption I've seen so far. http://www.e-cigarette-forum.com/fo...ncrease-vapor-flavor-th-941.html#post12066941

This is for a Kanger T3, but you'll get the idea. Machine screw coil
