Building coils with an allen key

[Cthulhurising]

I was wondering if anyone has tried wrqpping coils for an rba with an allen key. Does it take the hexagonal shape or not? If it does do you think the angles of the hexagon affect resistivity?

I used a teeny, tiny hex key to build a coil for my Kanger yesterday because all if my precision screwdrivers were too large to get in the little slot. I worked perfect, but a 1/16 drill bit will work as well I believe.

While I haven't tried using a allen key to wrap with, my guess would be that the larger the allen key the more likely you are to have bend's in the wire. I assume that the bends would affect overall resistance slightly. Sort of like when people bend while wrapping to make a diamond coil but not to the same severity.

I used a 1/16" allen key and it worked like a charm. That is what iwas thinking deleon, larger keys would give angles and angles most likely would increase the resistance

hi Cthulhurising, welcome to ECF...

I'm thinking if you use 1" (one inch) of wire
to make a coil, you will get the same resistance
from 1" no matter what shape it is in...

length x diameter of wire dictates resistance

not a scientist, just play one on the www

now 'surface' area exposed to juice might increase/decrease
due to different shapes and designs...

I've tried a nylon 'tie-wrap' (seen from ytube) and
made an interesting OVAL shaped coil...

made/tried a couple of those and never made anymore

toothpick (2mm) seems to work best for me

If you want to make the perfect coil every time, then get the Artistic wire gadget from Hobby Lobby, etc. Cost is around $11.00. Take a look at this vid.

Thanks pufZeppelin. My thought process was a hard angle could put more stress in that area and possibly cause micro fractures despite the malleability of kanthal thus raising the resistance.

Olefolks. I asked because this was my second coil build; the first had an id of 3/16. I was getting decent flavor but poor vapor/clouds. The only thing i could find in the house where i knew exact sizes were allen keys. I found a 1/16 allen key and tried it out.

So i have to ask if circular coils are best or is there a shape that would increase the ratio of the surface area in the coil to the volume of the cotton? or would that vaporize liquid faster than it can flow and dry burn?

PufZep said almost what I was gonna say, except that
a) THIN wire might be more likely to actually grab the hex shape - thick wire, you'd most likely get "almost round" coils.
b) Sounds like an interesting idea! I think the overall resistance will be based on the amount of wire rather than the shape - but the shape DOES impact wicking and surface area...

Shapes for surface area can get really complicated - people play with all kinds of things - split coils, twisted wire, etc...
I don't think we really have the science of it mastered - so your experiment could still be a great surprise, and a new find...

Cthulhurising you need to find a nice avatar to go along with your pseudo

Im still learning/perfecting my techniques in making micro coils. But as I read about the types of coils and kanthal, from twisted coils to ribbon kanthal, it seems everyone wants to increase surface area. If we can decrease the volume as well, that would mean more heat and evaporation faster

I've yet to use any

but I wanna try the flat ribbon wire

more surface area to atomize, sounds like a worth while try to me...
