First of all - Do not do anything, unless you have an ohm meter. If you don’t have one, you should get one before doing anything.
What are you vaping on? Mechs? A regulated device? An iStick? Some devices restrict your ohm range. The iStick 20W can only take 1 ohm and higher. Do you use a mech? Then make sure you have quality batteries won’t explode in your face, like Samsung 25Rs.
Google some coil building tutorials, like this one.
Watch some videos on rebuilding. Rip Trippers has a lot of tutorials on building.
To make it easier, you can get a coil jig, like a Kuro Koiler.
Steam-Engine has a cool tool, to help you build coils.
Dual coils essentially halves your resistance. Two 1 ohm coils makes a 0.5 ohm dual coil
All good points! Google and YouTube were my main teachers. I also hung out in a vape shop quite a bit when I first started out. You don’t know what you don’t know and that’s when ugly things can happen.
Again, I appreciate the good info. I have two regulated devices, an itaste MVP 3.0 and and istick 30W. It seems when building a RDA, you either need to sub-ohm or wind your coils with very fine wire. Lets say I want to build the RDA with two coils and a target resistance of .6 ohms. That means I need to wind two 1.2 ohm coils. To wind a 1.2 ohm coil with 26ga kanthal requires a length of wire 110.5mm or 4.35 inches. If your inner diameter is 3mm, that’s going to be a heck of a lot of winds. Of course going to 28ga would shorten that up some. Oh yes, I do have a digital multimeter, I used to rebuild pinball machines.
