Building my first coil

Also realized that I need 100' of kanthal

I too just started wrapping my own coils.

If you have an android smartphone or tablet you can download the Vaper's Toolbox app. It has been useful for calculating the number of wraps, diameters and wire gauges for the resistence I'm trying to get. If you have an Apple device, there are probably similar apps.

I'm not affiliated at all with that app, I just like it. YMMV

God bless the droid.
Done!

Length of the wire is the sole contributor to resistance. I use a Hobby Lobby coil winder jig and the 1.83mm rod to make my coils if I'm using cotton for a wick. If it's silica rope, then I use 2mm silica and wrap directly on the wick rope. A 5/4 wind with 32ga Kanthal on 2mm silica yields about 2 ohms. When you wrap a coil, the two ends are half wraps. When you look at the top, you see 5 wraps and when you flip it over it's 4 wraps.

The larger the wire diameter the more wraps it takes to get the same resistance. Rip Trippers likes to do micro and nano coils. With micro coils he uses smaller diameter 32ga Kanthal and 5 or 6 wraps and with the nano (smaller) coils he likes 8 or 10 wraps of 26ga or 28ga. But you have to consider that Rip likes sub ohm vaping.

There's lots of latitude in how you wind and what gauge wire you use. The best estimating method is to check the ends of the wire with a voltmeter after you wrap and before you cut the ends. Measure resistance at the length it will take to insert the coil and make contact (the point where you will break off the ends). That will tell you if you need to add or remove a wrap to get the resistance you want. The more you do it, the better you will get at estimating the number and size of the coils and the wire gauge it will take to achieve the right resistance.

I bet this is the jig he's speaking of. No torching, no squeezing, just wrap, mount, and fire the coil a few times, tapping on the ends if you need to.

Woo-hoo
Second coil looked much tighter, it fired and the burning carpet smell from the drop of a torched coil didn't happen.
Looks like I know what I'll be doing all weekend

HeHe - you're hooked now.

Hobby lobby here I come.
Move over grandma, papa needs a coil winder!

Haha.
Coil wasn't a bust. Mvp got here and it was a 2.8 ohm. Didn't think I had used that much wire but eh... little twister couldn't fire it....
Trip to michaels and nailed a coil at 1.8.
Sweet. Kayfun coming my way by fall

WoooooooW
1.2 coil on cotton in PT2 with air control at 9W with the virus.
What a vape!
