PT2 Coil

[englishmick]

All I've got right now is a bunch of PT2 tanks. I'm planning to pick up a Lemo soon but I'll still have all those PT2's so I figured I should learn how to rebuild the coils. I've never built a coil. Doing a lot of reading here and checking out youtube videos.

This morning I was cleaning an old coil which was hardly giving me any vapor from the PT mini. When I dry burned it I noticed it was heating up bright right away on one side but on the other side it took 3 or 4 seconds to turn a dull red. I started poking at it with a wooden toothpick. Didn't know what I was doing because I couldn't locate a magnifying glass and my eyes aren't too good, so I couldn't really see the individual coils. But after a bit of random picking I eventually got it to glow evenly across the coil. It performed like a new coil after that.

I don't know what I did. Maybe it was a matter of getting the coil evenly spaced. Or maybe the poking around was breaking off crud from the wire.

Tomorrow I'll pick up a decent magnifying glass and see if I can figure out what's going on. Maybe add that to my coil cleaning routine.

Jewlers loop would be better. It's tiny and tight in there. Basically your coil was shorted. Cleaning it fixed the short..

You might watch a few videos on youtube. About Re coiling the heads. I redo my Kanger dual coil heads as verticle coils. Once cleaning no longer helps or breaks the coils.

Not unusual, burned on crud covers the coil windings, continued heating (dry burning) will burn away the crud and the windings will then all glow.

My girlfriend and I have recently been learning how to rebuild the coils for the kanger heads. It sure is a pita, but we've had about 80% success with the ones we've done.

I might not need to worry about fixing old Kanger coils any more. My first roll of kanthal arrived today. I made one coil. Around 9 wraps of 30 g on a 1/16" drill bit. It came out at 1.9 ohms. Used a cotton wick. Actually that was my second. The first one I tried to get the wraps really close and ended up overlapping some of them.

Even with a mag glass I couldn't count the wraps. I think I did 9 or 10. Undid the first one per Mr Tripper's advice. I'm going to need to concentrate on counting as I wrap, or else get a bigger mag glass. I believe I should have heated it more than once, and maybe dunked it in water after heating, but I was impatient. It did seem to stay compressed after heating. Someone said to give it a first heating while it was still on the drill bit, but I couldn't get it compressed on the drill. Since I couldn't see it very well as I was wrapping, it started out rather open. I'll try the clip on jewelers glass that someone suggested above. Also supposed to dry burn it on the battery but forgot and stuffed the wick in too soon.

There's so much good advice available, here and on Youtube.

I've been playing around with the power. It seems pretty good at 9.5 watts. It tastes nice and gives lots of vapor. Actually after vaping on it for a while the amount of taste is almost overwhelming. I guess you get used to it. Like going from a cigalike to an Evod.

There's so many variables, with the coil and the wick. I guess it will take a lot of coils before I understand what's going on and figure out the best combination for what I want.

This is the most fun I've had since I started vaping. I'm going to order a Lemo tomorrow. But I've got several Protanks so figure I might as well learn how to rewire coils for them.
