Is Madvapes pre-cut coil a good start/price?

I notice they have pre-cut, pre-measured lengths of coil. Has anyone tried these? I wondered if it was a good price/value.

Hey bro, I would submit that if you have the abilities to install a coil and position it so it doesn't short your mod, you have the skillz to twist up your own. Check out this thread for a photo, step by step tutorial. You can do it. It is fun, intuitive and simple.

Ohmmeters are cheap and plentiful. Walmart, any auto parts store, Harbor Freight, Northern Tools, and even some drug stores sell them cheap these days. You can get something that works fine for under $10 and a better one for around $25 to $30. No one who's winding coils really needs a Fluke ($125 to $1000 and up).

I used to carry a Fluke 87 (around $400 retail). When I retired, I asked my manager about keeping my Fluke. He told me that as long as there was a company branded meter in the bag, he was fine with it. I searched all over for my old company issued Simpson digital to swap and couldn't find it. A few months afterward, I found it in a credenza upstairs. Too late! At least I have the Simpson and it's a good one. It just doesn't do frequency measurements, not that I'd need that anymore. I seldom needed that in my job, either.

If you order the items linked below that's the cheapest way and it's really not hard to make a coil, there's videos on it and instructions all over the place.

That's enough Kanthal to last several lifetimes and wick to last many many coils. I linked 32 ga Kanthal which I'd recommend in general not knowing what device or application you'll be using it with, 32 ga in a 4 or 5 wrap coil should keep you in the 2ish ohms range which is safe for any device. Less wraps = lower ohms so stick with 4 or 5 wraps till you can measure yourself and want to start tweaking. If you're using a big battery or unregulated you might want to go lower GA later but 32 is a good all around size.

You're going to need an ohm meter sooner or later for troubleshooting and checking ohms if you're building your own coils whether it be built in the mod which is easier and quicker or a stand alone meter which is more versatile and cheaper. In fact i think any vapor should have one whether they are doing RBAs or not imo.

If you want to get started and don't have a meter yet Kanthal A-1, 32 GA should get you in the low 2ish ohm range with 4 or 5 wraps until you can get one or if you want to get the pre-wrapped from Madvapes go for it but in the long run it's more expensive and nothing you shouldn't be able to do yourself very easily and quickly, there's really nothing to it.

You really need to purchase something to read ohms if you are going to be building your own coils. Whether it's a special box to screw atty's into, a pv that will read resistance or a multi-meter (I would suggest a multi-meter is a key part of a vapers arsenal) you need something.

Also, something like this will help

Resistance in Ohms/inch for the Resistance Wires

Kanthal Grade----- A-1 ------ A -------- D ----- Nichrome 60 -------- Nichrome 80

30 awg (Ω/in)----- 0.7 ------ 0.7 ------ 0.7 -------- 0.6 -------- -------- 0.5
31 awg (Ω/in)----- 0.9 ------ 0.9 ------ 0.8
32 awg (Ω/in)----- 1.2 ------ 1.1 ------ 1.1 -------- 0.9 -------- -------- 0.9
33 awg (Ω/in)----- 1.4 ------ 1.4 ------ 1.3
34 awg (Ω/in)----- 1.8 ------ 1.8 ------ 1.7 -------- 1.4 -------- -------- 1.4
35 awg (Ω/in)----- 2.3 ------ 2.2 ------ 2.1
36 awg (Ω/in)----- 2.9 ------ 2.8 ------ 2.7 -------- 2.3 -------- -------- 2.1

Right behind you
I think the pre-cut ones have non-resistance (NR) legs attached, either soldered or twisted, which saves a bunch of work if your atty setup requires them.

And non-resistance legs are...? Lol

@Fury83 thanks I will check in to them as well.

As for the set up I am using- I have a puck mod (the cell phone mod some have seen on the mod forum that 1lasttime made) using 4 AAA so it *should* be pushing slightly under 5v. I am using a 2.8 ohm head in my Vivi right now.

Lots of links to peruse, thank you :)
