First attempt Today to Recoil A vivi Nova (Not So Good)

[Steve K]

Well This is not as easy as I thought it would be,Did about 5 attempts to recoil a vivi nova head using cotton(maybe not the best choice to start with)But I am basing what I thought easy from The Pbusardo you tube video.It is very hard to wind the coil by hand and it always seems wider than the space provided,and everything is hard to see that small,Cotton is soft and that makes it worse,I got low ohm readings of 0.1 or readings of 3.0 and it fluctuated all over the place. I did a wrap around a nail and pushed the coils together which looked nice and smaller and pushed a small and pointy cotton wick made from cotton balls through the coil and it worked,got a reading of 2.4 ohms filled the tank and primed the coil pushed the button and the coils glowed,Then it just died.I also bought some cheese cloth but didn't use it yet.Don't know,very frustrating so far.

Using 32 kanthal

take the wick material and a toothpick or paperclip, then wrap the coil around them, check the spacing and remove the pick this helps you twist a perfect coil while leaving the right amount of room inside the coil for the wick to expand.
maybe that will help. i do not do nova heads but this is how i recoil a wick for my drippers.

Yes I did try this with a pin but damn if it isn't hard to get those wraps so close to each other without them touching,doing this by hand no less.How does anyone do this??

 

[Thrasher]

usually i wrap then close as i can if they touch i just straighten them out before removing the pin using a paperclip or little screw driver, i know if you scan around the RBA forum here there are a few threads on the nova head rebuilding maybe more tips there.

Do the coils touching increase ohm rating?

 

[pdib]

perhaps.

Am I posting in the right part of the forum for this topic??? I have a few questions to ask about recoiling for Vivi Nova and would this be better in the tank section of the forum.
