Hi why does my coil burn out

[frank 133]

Hi I have been trying to build a mesh wick,on a steam turbine on a nemesis,
I put 5 coils on,and it looked okay when pulsed .
But then the wire to the centre post keeps burning through.
should I try less coils ,thanks

ive been getting this happen to me mate,i find if i twist my 0.25 wire it stops it,if anything i would add another coil to bring the res up a bit,what resistance are the coils that are burning out,the higher the res the less heat to your coil.

don't use fresh newly charged batteries. Try putting a "kink" in the pos wire so its v shaped rather than straight. Should help?

cheers mate,I think it was point 4,I am using a multimeter,so it fluctuates a bit.
The wire is point 32,it burns through in between the centre post and the top coil.
I am totally new to making coils,but watched many videos on the subject.
I think its going to take a bit of practice,
I think I might be giving this new battery quite a hammering,I will have a go at coiling off the atty,its a bit fiddly in place ,thanks

nice one thanks for that ,will give it a go.

Is there room for a little one in this thread? Good suggestion @Reevo. I was getting the same prob with my Kraken today, I have done it with exactly the same amount of wraps as I would with the RSST with 0.25 and ss wick, also oxidised the wick with at least 6 burns of the micro torch. I pulled the positive tail in as tight as possible to the centre terminal on the Kraken but it just kept on burning out. I may be wrong and somebody might correct me, but what I realised was that the resistance was actualy 0.7 ohm on the Kraken. Would I be right in assuming the reason I was getting a higher resistance on the RSST is because it has the insulated hole? If that is not the case then I cannot understand why it is not averaging out at around 1.4 - 1.6ohm as it does on the RSST.

Rsst & Agat2 I now only use ss rope with an ekowool sleeve on the top part. So far its worked perfect everytime, no hot spots/legs. I just mess around with different guage wire and number of wraps, its now that easy. u8myufo, try not pulling the wire to tight.

 

[u8myufo]

Is that a purpose made ekowool sleeve you can buy then @Reevo, or do you just push the ss rope up through a normal piece of ekowool? What size ekowool do you use? Thanks.

I had issues with a hotspot starting from the centre positive post that kept burning my cotton wool wicks & on a genesis atty,making the juice taste unpleasant.I asked about it in another thread and it was suggested to use a tiny washer on the centre post,I had no washers small enough so made one from a piece of tin,being very thin I can bend it towards the wire coil & ever since,I've had no more issues.
u8myufo I'm not 100% certain,but I'd guess the coil is creating a negative path through the mesh.I used some fibreglass tissue to stroke the mesh wick over & built up a few strands on the wick where it goes through the base-plate.I was suffering ohms jumping about like a drunk kangaroo before I did this,afterwards...no more resistance issues.If you have no fibreglass tissue,then cotton wool can be used but beware of a hotspot setting fire to it(destroys your tonsils & makes you cough like a smoker with flu)

To be honest I think Reevo has sorted me out,the first coil I made was okay,then got over confident and tried a wick and mesh coil,that was when the burn outs started,I think with the first one I got lucky,then all the others went from bad to worse, I used a new battery,and kept pulling the top coil ,to close to the centre terminal,
I have been looking at the gadget called a kick,I will wait until I get more info on it before buying one.
I got one good hit off this nemesis tonight [first time I have used it]nearly choked me after all my clearamisers ,lol
