some general rda and mech mod questions

[EagleTa2]

Hi all

SWMBO bought me a Sigelei 20 and an IGO-L so I can enjoy rebuilding and i have a backup unit for my Provari to use by the pool...or as abckup in the unlikely case i have to send the Provari in for repair.

i have made a few coils with some success, but the arent perfect. they work good for a short period of time but then vapor production falls out.

my current setup is using 4 wraps of 31 ga Kanthal A1 around 3 or 4 thicknesses of silica wick i bought from fasttech. the fasttech websit lists it as 3mm but it sure doesnt look like its 3mm...

here come the questions...

1. how do you guys measure your resistance? with a multimeter? ob both my Provari and Sigelei zmax mini the resisstance of the coils are too low for the devices to measure.

2. Im using an AW IMR 18650 battery in the Sigelei 20. should I be worried at all about how low I am draining the battery? when should I pull it to charge. when I lost vapor, I checked the battery voltage on the Provari and it measured about 3.6v. my concern is that I dont want to damage the batteries by discharging them too deep.

3. im sruck in a hotel with basically nothing to do but play with my shiny things (what SWMBO calls my vaping stuff)

My tablet really doesn't like posting on Ecf...so I apologize for continuing this in a reply.

So, like I said, I'm stuck in a hotel to play with my vaping stuff...so I brought my cape kit with tools for making coils and wicks...but do not have access to my multi meter or drill bits or anything other than basic coil building stuff.

I would appreciate any help you can provide.

Thanks
Geo

i have same wick, i like to double it into a loop and wrap the coil on the two loose ends and put that near the hole.



usually if a mod cant handle the resistance then you need a multimeter.

i notice some drippers are fussy, depending on the juice. if it is thick or sugary you need to clean and dryburn more often, i rinse them every day. check the coil for buildup and dryburn if required to clean it.
make sure the coil is in a good spot for the airhole, my igo airhole is kinda low and i have to play with the coil to get into perfect position.

Flooding a dripper with too much juice will also kill the action of the coil faster.


the FT wick is very nice, sturdy and solid but i did have to experiment a few times to find a killer wrap. unlike other silica a good tight wrap works well as it seems to get loose once its been soaked down a while.

the prov and other mods will kill the battery at 3.2v but the actual drain limit is around 2.5 and the vapor will drop off long before this, im sure.

even a 1.2-1.4 ohm coil (which the provari will check) runs good on a mech for a while. the problem may very well be in the efficiency of the mech at delivering the voltage - with a strong drop the battery may read 3.6 but the atty is actually getting 3.2. (or so)

Thanks for easing my mind about the battery... I was a bit concerned about trashing my high dollar batteries for sure.

I think the air hole has a lot to do with the vapor falling off. The hole is pretty low. I raised the top cap and just set it over the first boring and my vapor volume and flavor increased...and not by a little...by A TON!

I think what I may do is consider drilling another hole that will be perfectly inline with the coil and just below the center line of the coil when it is mounted at the top of the stems...

Do you see any issue with having two air holes? Or would one air hole in the right spot be preferred? I can always block up the original air hole from the inside with some silver solder...or something.

Thanks again for the help!

you can try, it may get too airy but you can always fill them both then and then drill a different one. ideally the air should come and hit the wick dead on the coil.
i gave up on the igo and now i really dig the v5 and y1k from fasttech

glad ya figured it out, i was just randomly listing thoughts i had lol
