Hi guys and gals

I don't consider myself as having two left hands and usually I'm pretty .... about every work I do and most people that know me call me a perfectionist. Well... this time, thing aren't working like I wish and I'm starting to get mildy irritated with this whole deal about recoiling protank atomizers... I seem to making some mistake and I don't know where.

I was pretty much excited with the idea of recoiling your used attys instead of buying new ones. In my case, its not really about the cost (although any saving is always welcome) but more about the experience of recoiling and adjusting the thing. I thought it would be cool (no pun intended). ;)

Anyway, today was the day... I decided to rebuild my first mPT3 atty! I dismantled an old style atty, cleaned everything nice and proceeded to make a new resistance... I used 29AWG Kanthal A1 (0.30mm) on a 2.5mm torx screw driver (I checked with a digital gauge, it was 2.50mm spot on). The wire was pre heated like I saw it in many online videos and I decided to make a 8/7 coil. It went quite nicely and after finishing, I heated the coil several time to compress it to the point all turns would be in contact with each other.

After that, I inserted the coil into the base and added under it 1mm of ekowool, 2 x 1mm ekowool through the coil and 1mm ekowool on top. All in all, I have 4x 1mm ekowool strings coming out of the atty.

I tested the resistance under a multimeter and later on my zMax and also on a itaste VV 3.0V... all were giving me 1.8 Ohms.

So far so good... the taste seems to be better than that that was coming from the dual coils and the vapor production also seems quite nice. I tried several settings from 6W up to 15W... I ended up with 8W which seemed good enough for me to use it but don't short the battery's charge too much.

So now you might think... OK... whats his problem then? :) Well... my problem is that somehow, the connection between the atty and the battery isn't that great... it seems that when I screw down the mPT3 on the battery, the pin that is in the atty starts to rotate which twists the coil making it either short out or changing the resistance altogether... Its a pain in the .... and I can't figure out how to solve this problem... The stock attys don't seem to mind if you rotate the pin but my rebuild one will twist the coil and even jam the wicks between the atty's wall and the twisted coil.

How can I stop this from happening? I now must be constantly ajusting how the tank is screwed on the battery so that it doesn't short or show impossibile values.... this is starting to get on my nerves... help please?

Thank you

Regards
Tony

Hi, yes... true.

Problem was that although I cut the coil's legs as short as possible near the base and pin, the positive leg was 0.02mm too long, resting on the pin which you almost can't see with the naked eye. I removed the pin, cut the positive leg a little more and then reinserted with care the pin. Now when the pin rotates as you screw down the atty, the + leg of the coil isn't afected anymore... problem solved :)

Best Regards
Tony

I guess this is what you meant about being a perfectionist... O.02mm is a pretty small measurement!
