Good luck fstop.

Mac, i am talking about Nickel 200 not Nichrome. Nickel 200 alloy is 99 % Nickel. Nichrome 80 by contrast is 80 % Nickel, 20 % Chromium. There is a huge difference in electrical resistance between the two.
Resistance per mm for Nichrome 80 is 0.01346 ohms per mm, per Steam Engine. For Nickel 200 it is 0.00123 . Note the extra zero !
Maz I had read about Evolv's developments quite some time ago. It's the reason I slipped up talking about temperature in one of my responses to cigatron. My curious concern is whether it's use is more about temperature measurement or temperature limiting. All I can say. I think tensioned micro's keep temperatures right in the zone where they need to be when properly built. A lot to pay for a tech that you'd want to shut off to run a t.m.c. or micro. I like my performance without a rev or amp limiter. I'll wait for the video. Meanwhile YiHi!!!…

I don't think you slipped up Mac. I think I did! I too hastily responded to the notion that chipsets measured temp and airflow. Hadn't heard of the new dna40.
With nickel 200 wire having some 25x the temperature coefficient of resistance of kanthal (rise in res per degree of temp rise) the dna40 measures the res change and extrapolates temp! And because an increase in airflow cools the coil, causing res to drop, I guess it can be said that it measures airflow as well!
My bad, sorry Mac.

The Cigatron coil winder was the perfect instrument for this build ! Thanks Cig

I managed to build the vertical coil, and so far it's vaping beautifully. I did a spaced coil, since i wasn't having too much luck with the contact coil.

No probs Maz, glad to see you're putting it to good use.
So tell us about the vape. More vapor production or flavor than horizontal coils? More power required maybe? Heavy chaining capable?

Hello all. Thought it was time to introduce myself....as I successfully rebuilt three Protank coils tonight. I'm using 30 gauge Kanthal on 1/16 drill bit. I didn't quite hit my mark for resistances, but no shorts and I came close. I wanted two at 1.8 and one at 2.2 but ended up with two at 1.6 and one at 2.4. I was in a rush, so I think with more focus next time it will go a bit better. I've been lurking and reading this thread for some time. Not sure if all my coils were touching.... In fact I know they weren't, but I'm still pretty happy. They perform and taste better than factory. Next goal is to get them tighter and make a cigamajig to make things easier.
I did use cotton yarn as a wick....wondering everyone's thoughts on that. I thought initially it would help me get the sizing of the wick right. It fed thru the coils OK... But I suspect the flavor might be a bit muted. Still better than silica I think though.
I will be posting more in the future....but wanted to say thanks to those of you blazing the trails for noobs like myself. I've been vaping a little over two months. Was beginning to hate my protanks but kept seeing they had potential if rebuilt. Now I am a believer!
