Me Bonehead: Micro Coil Question

[Credo]

I've been making simple 2 - 3 Ohm coils on cotton and silica with 33 or 34 AWG for a while now...not bad.

I saw a vid of someone making one of these micro-thinggies...thought I'd give it a try.

IGO-W
28 AWG Kanthol

Planning a single coil build ...

I make my coil around 1 Ohms (I use a pass-through with a breaker for this sort of tinkering).
It's wrapped around a 1/16 hex wrench.

Just as I'm about to do the 'squeeze the burning coils to make them stick together step' shown in the vid...It occurs to me...
WAIT! This will cause a HARD SHORT!

So I stop here and feel really stupid for a moment.

Instead I heated it up red hot, let the button off and squeezed it a bit.

Is this correct?

If not...what tool are people using for this step that won't cause a hard short?

Strange...perhaps it's just in my old mind paying tricks on me...but in the heat of tinkering I almost did something REALLY STUPID, which could be really bad with a battery based rig.

Hit the nail on the head. You squeeze them with conductive metal tweezers while firing and you've got a hard short. Light the coils for a bit until glowing really hot, let off the fire button, and then quickly squeeze the coils together until they stop glowing.

The other method is to heat them with a torch as you're squeezing the coils together.

Lighter and tweezers can work.

If you take your time and insure every wrap is tight you won't have to squeeze them. Squeezing just fixes gaps you left while wrapping, but it won't fix the slack left from coils wrapped at an angle.

I fire, release when coil glows then squeeze. No matter how tight I wrap em (and I can wrap em touching) this improves the evenness of the glow big time.

How exactly does this increase performance?

^ when you first mount the coil and fire it it will glow uneven and possibly even hot legs. Once the coil is fired, released and squeezed a few times the coil will glow perfectly and hot legs dissapear.
