How many wraps would I need for about 1 ohm?

[niamh297]

I'm using .25 Kanthal to do microcoils in a protank head, I want to switch to .3 Kanthal so I can do more wraps to cover more of the cotton. I am currently wrapping coils around a 2mm jewellers screwdriver. Someone sent me a link to a program to work out how many wraps you need, where you type in all the details and it calculates it, but I cannot use it on this computer as the Linux system won't let me open it. So I wonder if anyone can help me: how many wraps of .3 kanthal would I need around a 2mm jewellers screwdriver to get about a 1 ohm resistance? Or should I wrap around something else?

Hi Niamh,

This is another Super-Shiny guide
allaboute-cigarettes.proboards.com/thread/39221/coiling-chart

The chart says 8 wraps will give you 1.4ohm, so try 6. Should be about 1ohm.
I hope it tells you everything you need.

Phil.

I did a 6 wrap micro coil on my kayfun build video and it came out at 1ohm.
