Help with Kanthal wire and coil making?

[dj9928]

I have 2 kinds of Kanthal wire, I am unsure which exactly, possibly 30 & 32g. One is very light and flimsy, on a 1.5mm drill bit about 5-6 wraps gives 1.8Ohms, it also heats up extremely quickly.

The other Kanthal is very thick and stiff, 7-8 wraps on a a 1.5mm drill bit gives 1.2 - 1.5 Ohms, this doesn't heat up quickly.

Now the issues I have is I am using a kayfun on an MVP 2, The first kanthal is very flimsy to work with, the coils go all over the show when pushing the cotton through, the second kanthal takes to long to heat up and is just not great on the output of the MVP 2.

So for my MVP 2 I need something that heats up quickly and isn't flimsy, any ideas or help?

I'm sure someone that knows a lot more than me will come along and help you. If it is flimsy I would think it is the 32 gauge Kanthal. I used 30 on the Kayfun before I retired it, and had no issues. It really all depends on what Ω's you are shooting for. Here is a chart that may help. It is the one that I use.

Sorry I was not able to help you more but others will. Good luck to you and happy wrapping.

What wattage are you vaping the KF at? I'd say below 10 watts, go 30ga, and above 10 go 28. Both are easy to work with. 32-34ga, which sounds like the "thin" stuff by the numbers, is kinda a pain in the ... for the reasons you described.

I always had the best results on my KF with 28g around 1.2 -1.4 at about 14 watts. 32g is a nightmare to work with alone, it is best when use in some form of a twisted coil. 30g is a bit easier, but I would recommend work hardening it to give it a bit more rigidity, either with a drill or the z-pull with a cloth.

So it seems I have got 28g 3mm Kanthal.

3mm would be a rather big wire. I think you mean 0.3mm which is between 28ga and 29ga. We don't use the American Wire Gauge over here.

I wouldn't expect you to be having more difficulty than anyone else. I'm using 0.25mm right now and I've re-wicked it several times. It does take a light hand and a bit of practice.

My 0.2mm (32ga) is rather too thin for a micro-coil and cotton, but it works fine wrapped around silica.

The secret seems to be with 28ga and the MVP make smaller coils, they seem to heat quicker, so tried a 1mm bit working like a charm but a pain to get the cotton through and I worry about it wicking correctly being so small

28ga is great wire to start with as its sturdy but not so hard to wrap with. 32ga is a pain to work with, but it can be done with smaller inner diameter. I'm a year into rebuilding and personally prefer 28ga.
Another note, I put 1.2-1.6 ohm could in my kayfun but usually run them over 11w, which is the limit on your mvp2... May be time for an upgrade... I saw some good deals on the 20w and the istick seems to be very popular and decently priced.
