Nicely done Rom !

Hi Rom,

P Busardo recoiled the 'Ithaka' with cotton - very good vid.

Out of interest, have you tried SS mesh instead of cotton

Mesh makes me really don't like that stuff

  But just think of the advantages of an extensive layer of SS mesh in your garden, wired up to a decent Voltage....No more unwanted visitors!!

Hey Rosco, I use .30 Kanthal for my micro-coils...the thicker the wire, the lower the resistance. This enables you to put more wraps without increasing your ohms excessively. The more wraps you have, the more wick you can heat. But there is a trade off for using thicker wire and that is it takes a little longer to heat from cold. The length of a wire determines the resistance, so a 100 mm length of wire will be the same resistance whether it is 1 wrap around a baked bean tin or 36 wraps around a pin.
You will have to make the internal measurement based on what size wick you want to thread through. You cannot drag a 3mm. silicon wick through a coil wrapped around a 14 gauge needle without strangling the wick and that is if you could get the wick through such a small hole. That is where using cotton wool or bamboo wool is the way to go when using a micro-coil, they both compress when pulling through the coil without the worry of strangling the wick and with cotton wool, if you try and pull too much through, it just breaks.

This is the gas torch that I got from Fasttech but they dont have them now but here is the same one on Ebay for about the same price also from the Far East, this is a great bit of kit and worth buying a couple to have one as a back-up.

Cheers

Neil

Thanks greigster. I am re coiling nova heads tonight so might have a bash at a dual micro coil with .2 kanthal as a practice and some cotton wool in my igo w and see what happens.

Interesting point from the P Busardo vid,

When dual coiling, using the 'X' method, he placed a strand of cotton coil ,on top of the first coil,
thus stopping the potential of a 'short', to stop the coils touching each other.

Don't really matter if the coils touch each other mike weaver93 as long as they don't touch the drip tip (juice opener)....i learned the hard way with that one
