3/4 4/5 8675/309

I've been trying to decipher what people mean by 3/4 or 4/5 coils... is it 4 or 5, 3 or 4? 3 quarters? pick a number!

No seriously... what are you folks calling a 3/4 or 4/5 coil?

 

[spraintz]

when you wrap a spiral coil, look at the coil from one side and it will have 3 coils and then look at it from the other side....4 coils = 3/4 wrap

It's a more accurate way to describe how many wraps you truly have. The idea is if you tell somebody to make a 4 coil wrap one person might make a 3/4 wrap and another might make a 4/5 wrap depending on how they look at it.

make sense?

4/5 wrap:

4

5

shouldn't we be counting 'coils' by 1 full circumference? Which would make that a 4 coil set up not a 5. 1 coil should be 1 time around the wick... I guess that's what confused me. When I look at both pictures I see 4 coils, sure I see 5 instances of wire in the second picture but it's still 4 coils. Who am I to fight the tide, I'll just assume when I see '4/5' that they mean 4 coils, 7/8 means 7 coils, etc.

I agree it's a lil weird, I thought the same thing when I got into rebuildables. Sometimes you just can't tell a given person's perspective so at least a denotation of "4/5" it technically more accurate when describing a coil wrap over the internet. Heck, on some of my RBA's I wrap 4.25 or 4.75 coils based on how the posts are positioned but forget trying to describe that in text to somebody who is just starting to make a coil and doesn't know....

But yes, for me I consider a 4/5 wrap 4 coils.....

I was wondering the same thing. I kinda figured I was correct in my assumption. Thanks for this thread! Regardless of wraps, I have variable wattage on my RBA w/ bottomfeeder, so I make eleventyseven/twelventeen wraps and it's all good.

 

[Lance_Wallen]

Yeah, the mod I'm building right now is a hybrid genesis RBA with a DNA board in it. I'm not gonna care much about the coils outside of using low gauge, lots of coils for increased surface area to vape on

This will give you an approximation but if you really want to get technical, it's all about the length of wire from post to post so one person's 4/5 wrap may be another person's 6/7 wrap if they use different sized wicks but the length is the same.

That's why i have a set of alligator clips hooked up to a multimeter and move the clips on the uncut wire until i get the desired resistance, cut, then wrap.

I enjoy reading & benefiting from spraintz detailed well written "to the rescue/assistance" posts.

Very good indeed.
