Which Nickel Wire?

[Q]

When you're talking about 0.25 wire I take it you mean 30AWG like this or this
Now do I need res or non res?

[hijack]

I just thought I would put this question here instead of new thread.

I have made a few coils while my TC mod is on way (practice) and have noticed that they are coming out lower than they should(steamengine).



Above is a 9 full wrap (i think), coil of .3mm NI200 which reads .15 Ohm on my FT meter.
Steamengine is saying it should read .18 Ohm.
Do you think its likely my meter is a few points out? or am I missing something from what you see? robby VapingBad Ripshod @scooby

To be honest, I have been really impressed with the resistance reading of all the TC mods I have, I would trust it more than an ohms tester personally. The contacts must all be scrupyou lussly
very clean , it is a tiny amount of resistance. Personally I wouldn`t worry about it till you get the mod and test it there

hijack I wouldn't worry that's near enough, there's lots of variables and we are talking really small differences here. Your wire may be slightly shorter in total than steam engine, the wire ID will have a tolerance so may be slightly thicker than .3mm or not uniform. Your meter may be out as you suggest also.
The important thing is what it reads on the mod you use it on at room temperature and that the reading is stable.

I wouldn't worry about 0.03 ohms difference.

The problem was more when I had tried duel coiling an atty and was getting readings of .07 instead of the .11 that I was aiming for(as Mod will only go down to .1) and was ending up doing 11 wraps per coil using the .2mm wire, way to big for a nice fit.
Ill just assume for now that the meter is a few 100th out and when the mod gets here Ill have that 7 wrap duel coil in there, no problem

Got to say, I am finding using nickel is much easier to coil and set than kanthal....Great stuff.

If you have room for wider wraps, why not try 4mm. That`s what I use all the time in my drippers, pulls the width in nicely (less wraps) hijack

Thats what I try and use as well robby and is what is on the Monster's deck above.
Have 2 4mm metal bars(from Rose atty) that I use.



as well as the threaded former.

I would trust the mod more than the metre, but I must have been lucky with my FT metre it is very close down that low.

For dual coils on the Origenny2 I have been using twisted 0.16 mm with the DNA40s (2 strands 6 or 7 wraps on 3.2 mm wicks sleeper coil 0.10 - 0.115 ohm), but now I have a DNA200 I can use 0.3 mm (same except single strand 0.060 ohm). The 0.3 mm has a tiny stubborn hot spot that you can't see and I got impatient so first just put the temp up 20 F, but with the DNA200 I can set & lock the ohms to whatever I like so set it to 0.063 ohm then locked it and it vapes perfectly. So the device reading does matter, but with experience you can compensate to a degree by changing the temperature. The Evolv refinement mode will get past this problem to a degree by tracking the resistance and temp while idle, but other devices your only recourse is temp adjustment.   This was the first time this year I have had to go above 400 F, IMO if you are not getting a decent vape at 400 F (maybe a bit higher for higher VG) you need more wraps, you may need to go down a wire size to do this.

For dual coiling with cotton the best result I got was again with twisted 0.16 mm, but I had to use 3 strands because of the poor through hole terminals on the Orchid clones. These end up such big coils (12 wraps on 3 mm wicks) they have to be touching so sometimes short between loops it it gets knocked, you just need to strum it to clear the short. I also found on this atty that more wraps were generally better, too few and the heat is not spread enough and the temp limit kicks in too fast, I think I use more than double the wraps I use with Kanthal, but I like thin Kanthal so the iStick doesn't take an age to get to temp.

Only thing I can add to what's already been posted hijack is the leg-length you're using in steam engine.

I suggest - as they're full turns on the coil - is to measure the distance between the inside edges of the post screws and divide by 2 for the leg length. It'll be more accurate than guessing or trying to actually measure them.

Looks like my question got overlooked in the rush

Lets add ANOTHER question to the mix, what about titanium?

I need to get SOMETHING ordered today, so what should I go for?

Yes 30 AWG is 0.25 mm, but I would only get the Ti from StealthVape mainly for health reasons, but the different alloys have different TCRs.

[Q]

Thanks VapingBad OK then ni200, res or non res?

They should be the same Ni200 is a specification or standard for >= 99.6% pure nickel alloy, res or non-res is just the application.  But the one labelled res has more good reviews so I would go for that.

[Q]

Just had a look at Stealth for the Ti..... more confused than ever now, what do I need to buy VapingBad
