Help with coil building

[nwhornet]

Hi Jaffacakes In Steam I set it to 28 Kanthal A1 dual coil target .2, 3mm ID and it then says 2 wraps. Surley thats not right when most coils are 4 or 5 wraps.

You wont get 0.19ohm from that gauge wire or Kanthal. Ni80 or SS316, 26AWG core will work far better.

You could twist your 28 gauge... it would mean it has 3/4 wraps...

But yes if you want to build that low youd need 24 guage.

If you are stuck using that wire in the short term, you could make a pair of parallel wrapped coils.

A parallel wrapped coil is just a coil made using two strands of wire instead of one. So you would cut 2 lengths of your wire, put them next to each other on your coiling jig, and wind them as if they were 1 wire.

A 3 wrap of that 28+32 wire in parallel would actually have 6 loops because there are 2 wires, and come out around 0.4 ohms per coil. 4 wraps would come out a little over 0.5 ohms per coil. That's with a 3mm inner diameter.

That could get you down to 0.2 - 0.27 ohms in a dual coil setup.

I'm not sure how fast it would ramp up/cool down, due to it being kanthal.

Thank you all, I have some ss316 26ga and I can do 5 wraps 3mm to get .4 so dual would be .2. approx.
Thank you all for your help. IMO i think the Drop is better than the Dead Rabbit, but both are awesome.

Thank you all
