Core 28g Kanthal Wire Keeps Breaking

[NYCVape]

So, my issue tonight is that I was claptoning a 28g with a 30g kanthal and it was looking pretty good (as experiments go) and the core breaks in the drill chuck, reset, breaks again, reset, breaks again. It's a new drill that worked great on a twisted 24g core.

Since I am new -- I am trying to figure out what works with what.

Is kanthal too soft? Am I trying to clapton too light a gauge? Would SS or NiChrome have more tensile strength?

If you could share some info on working with different metals and gauges, that would really help.

Thanks,

Andew

Too much movement of the wire = metal fatigue!

Getting the hang of it now

My chuck won't bite lower than 27g.
Take an eye hook and stick it in the chuck.
Loop over the swivel and twist, repeat on the eye hook.
Also use a smaller wrap. 28g doesn't have enough mass to efficiently heat 30g and the tension required to wrap 30g will probably break the core any way.

Stainless and Nichrome are softer than Kanthal.
Any other questions you can ask here, message me or come to the coil porn thread.
Inevitably you'll end up wanting to alien then wrap staples etc...

You using swivels? single core Clapton I avoid swivels and just let the wire rotate freely. if you do this you'll want to move the drill back a little as you get a longer Clapton. usually it breaks by the chuck when I have a wide swing from the Chuck to my fingers (picture a jump rope). 28g with 30g kanthal will have quite a long ramp up time. most of my builds are 30g core with 32g or 36g kanthal, 5 wraps 2mm I'd coming out around 1.5 ohms.

Yep, I am using a swivel and the core wire gets fatigued.

I got it sorted out -- longer wire held more straight. I can't clapton without a swivel, just don't have the technique -- but I am still learning.

Thanks!

I can't either.

I use swivels also, but it's a bit of a pain with single core clapton, most all I build are fused with 2 or more cores. I've seen where someone used a shipping tube at an angle, that settled down the flapping significantly. But for me the swivels work fine and it's what I'm used to.

'Ghost vapor' on Youtube is the guy that i saw using the tube to stop the wire from flapping.

If you want to know how to pinch the wire to clapton it you can watch some of Twisted messes videos, in the following video at 12minutes you see him doing it, he's wrapping over multi cores but its the same technique, just trap the wire between your thumb nail and forefinger and don't let off with the pressure
