What size drill bit?

[genevieve]

Hey guys,

Attempting again at rebuilding. What drill bit size would some of you recommend using for both micro coils and regular coils?

 

[savagemann]

Most people are using 1/16" for micro.
I personally use 5/64"

There's a huge difference between 5/64 and 1/16....right?

I prefer using a 16g blunt tip needle, way lighter and it has the plastic plug at the end you can push the coil against to bunch it all together.

A paperclip? Damn. I've actually wanted to try that method (resting the coils on cotton).

We'll.... I have a 3/32 and a 7/64. Gonna try the smaller one first.up til now, I've used the 5/32...much bigger than both these.

Micros: 1/16". That's all I roll.

Regular: If you have a drill index lying around (that's one of those fancy sets with all of the sizes, from fractional to letters to numbers), find the drill size that almost exactly fits the wick hole on your RBA. Use a drill bit in that size, or a few thousandths smaller, that is tall enough to stand in the tank and extend past the positive post of your atty. This is assuming you're building a genny. Wrap the coil on the drill bit, slide the bit in the wick hole, and install the coil legs to the posts before removing the drill bit. Super easy, perfect tension, awesome.

If you're talking drippers, I'd say use a drill bit that corresponds with the size of your favorite wick, so that it's easy to get in there, but has enough contact with the coil.

I should mention I'm using a igo-w dripper.

There is exactly 1/64th difference. Best way to tell the difference is to look at a ruler marked with 16ths. Now imagine that 1/16th is divided into 4 smaller sections and the difference is one of those sections.

Alternatively if you have a 1/16 bit and a 3/32 bit, a 5/64 is exactly halfway between those two sizes.

As I mentioned in the other thread where you asked this. Coil diameter depends largely on wick choice. What do you plan on using?

i'm using a cotton wick.

Here's the inside diameter range of micro coils. It's broken down in gauge/inches/metric

If you are using pulled cotton (pulled from a cotton ball, q-tip, or something like that) then you can use any size coil you want really. If you are using cotton yarn, I have found 1/16 to work nicely.
