Went to the Hardware store and

[JasonBourne]

So I went to the Hardware store today because I am going to start my kayfun rebuild today, very excited. I picked up 5/64 and 1/16 drill bit, but it looks so much smaller in person than on the youtube videos. Did I pick up the wrong sizes? Were they suppose to be
1and1/16 1and5/64? Maybe when they do their rebuilds on youtube they zoom in and it looks bigger but this looks about the same size as my coil on my protank heads or maybe just very very slightly bigger. I appreciate all your help, because of this forum vaping has been very pleasurable.

You got the right ones.

Do you just intend to make microcoils? Those are the correct size drill bits for it.

 

[JasonBourne]

Thank you so much for your help, yes I intend to make microcoils. Im glad I bought the right size drill bits. Going to be testing out the 28g and 30g kanthal wire and play around with the wraps until I get about 1.0-1.4 ohms. Hope you have a great rest of your weekend!!!

Try 10 wraps of 28g on your 1/16 drill bit. That'll put you in the ballpark.

I felt the same way after I built my first micro. They are tiny!

1/16th is tiny. I got three of them. The guy at the hardware store had to search through all the drawers to find it and even he seemed surprised by its size.

Same here. I bought one of the nice ones out of the locked case, and when the clerk reached in to grab it he's like "If I can get a hold of it... these are tiny!". I figure I can drill through SS caps more easily in the future if I have a good bit, better than dulling a cheap bit every time.

You can buy a 10 pack of 1/16" drill bits at Harbor Freight for a couple bucks.

1 1/16" and 1 5/64" bits? They would be almost 3 cm wide!

But like others have said, yes you bought the right ones. Microcoils are supposed to be very small. In fact, I think that even 1/16" is too big. I've had my best results with a 3/64" bit -- just 1.2mm wide.

I believe that would be considered a nano coil. I've actually had trouble getting those to wick properly, but to each his own. A lot of people have good luck with them.

You got the right ones JB... Now you are setup for doing a micro, (1/16"), and or a mini, (5/64", coil on your RDA's. Depending on how long the legs are after you build your coil, I would think as Rule pointed out already, 28g 8-10 wraps @ 1/16" should net you in the 1-1.4Ω range...

Not trying to hijack this thread. But could someone please explain why 28g as to smaller wire size say like 32g? I seem to be trashing up coils DAILY. Would 28g be less prone to crudding up compared to 32g? Someone mentioned in another thread that the heat up time is slower on the 28g. I've never actually burnt through any coil, but after a day of use, they are black and working poorly. Then I rebuild again.. :-/

The 28ga has less resistance per ft so it takes more coils to get the same resistance as 32ga. This gives more heating area on a micro coil.

 

[nostinkies]

So more heating area amounts to a longer lasting less cruddy coil?

 

[sawlight]

As I understand it. I don't build micro coils, and still like my 32ga, so I can't say from personal experience.

I use 27 gauge Kanthal for all my coils. I make them between 1 and 0.6 ohms. The thicker wire gives a lot more surface area for the watts to work on so you don't burn your juice at higher power. IMO this does not make for any less gunk on the coils, but I've never actually tested this.

I typically make micro coils with cotton wicks. I can remove the wick and dry burn the coil to very quickly get rid of the gunk. Re-wicking is easy, fast and cheap. I find with gunky juice I re-wick every couple of days. With clean burning juice I can go over a week. The thicker wire does take longer to heat up, but it's not a problem for me. Vapor production still starts very quickly. The coils last for weeks.

The gunk on your coil generally has to do with the juice you're vaping. Some juices, particularly 'candy' type flavors, will tend to gunk up coils quicker than clearer juices.

you can take unflavored eliquid and go for months on a coil.

i consistently get 1-1.2Ω with 10-11 wraps of 28g kanthal on a 1/16" bit. slight variances occur depending on the leg length between coil and post.
