Square coil???

[jchadbourne]

Anyone ever try to wrap a square coil?

 

[_sidekick_]

Why? The electricity would not flow smoothly and might cause hot spots.

Just wanted to play around.. I have a 1/4" rod that I ground down to about 1/8"

Well, electricity doesn't flow, current does. And current doesn't care about 90 degree turns. Look at circuit boards that have foil traces that abruptly turn 90 degrees and function perfectly. In this case I think it's more a question of the difference in mechanical efficiency, heat transfer etc...between a round and square coil...a "squoil"? Might be worth a try to find out, at least a google search - I can't believe the NOBODY has tried it.

Just did it and.......it works its not real pretty but it works 6 wraps of 28g came out to 1.9 Ohms and makes crazy clouds

Better than round ones?

 

[jchadbourne]

Better than any 1.9 I ever made I tested it with some gross juice I got for free so I cant comment on flavor but big clouds I'm gonna try another one in a lil bit

i have seen a few square coils made in the last couple years here on ecf, one by pdib comes to mind.

Good idea then. I will also try it as soon as I find such small square rod. Thanks.

You will get hotspots on all the corners. These are also most likely to be the places with least wicking contact. Sounds undesirable, but that's cool if it's working for you and probably looks pretty nice.

 

[jchadbourne]

I didn't notice any hot spots and the corners are not totally square they are slightly rounded no kinks.

Care to throw a pic of it?

 

[jchadbourne]

Sideview of the first one. I'll post more of the second one when I do it

Hey, it's your baby.

Don't get it really, no real surface difference to speak of, and with cotton or hemp, it would plump to the coil dimensions regardless of the shape, prolly a negative with silica.

Interesting idea ... but I prefer curves

 

[SLIPPY_EEL]

I think its gonna be tough keeping the coil square... what I mean is the first square being square to the next and so on.... a square with curved bits comes to mind

 

[SkvLTD]

Only thing I could think of is some kind of square SS mesh to go through and fill that properly, but indeed no reason for it not to work.

I don't think the idea is really to make a square coil.
This is it here

Just wanted to play around.. I have a 1/4" rod that I ground down to about 1/8"

1/4" ceramic rod, and it's easier to grind it down to a square 1/8" crosssection instead of trying to make it circular.
