Twisting NI200

[Paul lamb]

As above can I twist it? I currently use 28 9 wraps .09 ohms if I twist it how many wraps are required?

How many wraps for what, the same resistance? What's the ID of the coil you want to make?

Thanks

I am looking to have .1/2 ohms, just with twisting it may not be possible

.1/2ohms?

.1ohms or .2ohms, maybe?

You already need a few more wraps.

Currently 9 wraps is tight with out coils touching so putting more wraps would be to much of pain? What you think?

Bump

Anyone twisting 28ni200 or similar

well when twisting wire one needs to consider the number of wires used, the twists per inch, the factor of increasing ohms since as one twists the wire tighter and tighter the actual length of the wire decreases thus making it have more resistance than an untwisted length.. its not all that simple...

So 9 wraps at .09/.1 by twisting it I may have to double the wraps? Which in a subtank there is no space for much more

you might get .1-.15 with a 2 wire twist at 40 - 50 TPI ( twists per inch)... with 26 - 28 ga.

Yeah looks like I may need to try a thicker wire

Cheers

Thinner wire. Thicker wire has lower resistance. If you want to try a twisted TC build, I would get some 32G.

I do twisted with 28 gauge wire on a mutation X V3. It takes more space than would fit in a subtank to get to .1 Ohms if that is the question. I've got single coil with ten wraps and it's reading .08 right now. The resistance of NI200 is so low I think it would be tough to get to .1 with any gauge in a subtank RBA.
