I'm at day 93 smoke free at this point and time. I've been rebuilding coils using all different cotton products. Cotton balls, cotton yarn, cotton cheesecloth, and I just bought cotton butchers twine today.
For the last 30 days I've used cheesecloth in my MT3's. I don't separate the threads, I just roll it up to 3mm wick size. It's a bit sloppy looking as for the cotton threads oriented in the opposite direction of the horizontal way a wick is,,, but,,,, it worked fine every time.
I however hold a paper clip sized piece of wire along side the wick as I wrap the 32ga. kenthal wire around both the wick and wire,( 5 wire loops to top, 4 wire loops at the bottom of the coil ( also known as a 5/4 coil wrap) Leave the end wire leads long enough to go through the coil/wick chasey. Then, make sure to have slight spaces between the coiled wire, ((COIL)), and then pull the paper clip wire out. Slide through coil/wick chasey and complete the positive and negative connections with the rubber grommet and metal positive post. ( Many videos on YouTube showing coil rebuilding this way.)
NOTE: You will need a mod that reads ohm,s . This will insure no shorts in the coil, as well as telling you how many ohm,s the coil is. ( $35.00 COMPLETE VAMO SET UP FROM VAPOR BREAK,,, VAMO, BATTERIES AND CHARGER. )
NOW
Here is my experience using cotton. After 30 or so days of cotton cheesecloth wicks ,,,,and getting great vapor clouds and plenty of taste from my home mixed VG ( Glycerine ) e-juice, I started getting an annoying cough. As though something could not be cleared from my throat so easily. ( Nothing compared to my 3 pack a day BARKING COUGH) Anyway, I switched back to a new stock MT3. Within a few hours of vaping , my annoying slight hack disappeared. I will have to experiment with cotton butchers twine I purchased today. This twine is light brownish in color and very much resembles the twist look of a silica wick. I boiled 5ft of it for 15 minutes, rinsed with filtered water and boiled it again for 10-15 minutes. Patted dry with paper towels and now letting it completely dry between paper towels.
i will post pictures some time soon showing the steps of easy coil rebuilding. Unless your eye sight is great, you will want a free standing magnifying glass. Some have lights and mount to a desk (or) as mine is in the fashion of a head band. It works great when positioning the spaces between kenthal wire coil turns.
