Beginner wants to learn RBA

[kailey]

I've watched thousands of videos and read hundreds of tutorials on how to recoil rebuildables but I think my basic understanding of electronics is lacking and I would really appreciate some help in the basics.

I am using a Maga RBA Kit which is a Genesis style RBA. Todd recoils it in this video:



The problem I am having is that the coil starts off with quite a high ohm reading but then goes very low. I have recoiled it multiple times but always have the same problem. The last one started off at 2.5 ohms and after a few fires it went down to 0.8 ohms which is too low for the Vamo. I have tried to get the coil even and snug against the wick. Am I correct in thinking my lack of skill in this area is what is causing me the problems or could it be something else?

Sorry for the very basic questions but I do want to learn this. If anyone knows of a dummies guide to basic coil making please let me know.

Ah, it looks like I should have played with the coil a bit and moved them up and down a little. What a pity I took the coil out and threw it away.

At least I am getting plenty of practice at recoiling.

RBA can be a pain really its trial and error

firstly is your ss wick oxadised properly ?
is it a snug fit in the hole ? (not to tight not to slack)
if you made the wick is it rolled to tight or to loose
the coil should be on the wick but not so tight that it strangles it and not so lose that it moves to easy
i had a coil doing prity much what you are talking about and it was to lose
as for playing with the coil well nearly every time i vape on it i have to tweek it (pain in the arse) so hardly use it now
will be testing ss wire today hope it makes a difference

kailey a lot of people seem to be going down the rope method, ain't tried it myself, can't be bothered with all the faffling plus my juices like wick, you might like one of these with 2mm ekowool and 0.2 kanthal fitted:

I'm not going to explain my method, because everyone has their own preferred way to do this
but I will explain some of the issues.

Getting a coil to work is dependant only one thing - that it isn't shorting on the wick.

If you use the peterK method and wind the coil around a drill bit or other former - which you
then pull out leaving the coil on its own it will always glow evenly. This demonstrates that
it is the coil wick interface that is the difficulty for some.

Another thing to consider is the wick passing through the deck, if it is too tight through the hole
or pulled to one side it will get a solid connection with the negative earth of the deck. So you don't
want it too fat and it should be nicely centralised as it passes through. This is why some Gennis
have insulated wick holes, it takes one of the problems out of the equation. The cheapest I can
think of with this feature is the RSST.

Once the wick is not earthed then fixing the coil means a short on the coil is a minimum of two points of good
contact allowing the power to bypass some of the turn on the coil. This is much easier to fix than an earthed coil that
just need one contact to short the circuit.

Something I have only seen explained in two "how to" videos is that it is very hard to fix a short on a wet wick.
You can not see where it is shorting as the juice is cooling the wire. You need to work you coils into an even glow
while they are DRY. Start with very short dabs on the power button, if you have adjustable power/volts then dial
everything down to minimum. Start with an almost discharged battery if your using an unregulated device. Keep
dabbing on the power and gradually lengthen the bursts until you can see how its glowing, take it slow. If you
are getting a short try moving the wick or a small reposition of the wire normally sorts it out. Don't be tempted to
put a few drops of juice on until its glowing like an electric fire, you will need to turn up the power or fit a new battery on
most coils to get to this point. Only then can you add some juice and enjoy.

Hi kailey. For a novice genesis rebuilder, I would strongly suggest you use the PeterK method of setting up your coil and `pulsing` it on your att`y.

see video :http://www.youtube.com/watch?v=iJhReR_IhIE
Hope this helps you achieve success.

this one is the best way

For some reason I didn't receive notifications from the forum yesterday and didn't realise there were any replies but on my travels to find some answers I came across the PeterK method. I just need to find something of the right size now.

punisher, the RBA came already set up so I am just using the wick it came with. I am almost sure it has already been oxadised. I have been so busy trying to get the coil right that I didn't think of the implications the wick would have. I think I was lulled into a false sense of security with it being already made up so it is something for me to check today. Thanks for mentioning it. 

Super-Shiny the rope method is a good idea too. Will try that sometime. Thanks for the Aga-s suggestion too. I will research that option a bit more.

markm Thank you so much for the great information. I really appreciate you just going over the basics which are probably just common sense to someone with more knowledge but very much needed by me.

jeffc thank you for the link to the video. I haven't had a chance to try out this method yet but it looks easier than what I was trying to do.

Super-Shiny love that PeterK method too

I have lots to think about and try now. I will let you know how I get on although I may have to purchase some more wire as my stock is a bit on the low side after the mess I made my experiments.

It might just be me,but I find ribbon wire easier to use and there is a lot more wick coverage.I have been using the drill bit method and it seems to be the easiest way I have found

I'm following this thread with interest as I'm seriously considering an RBA but can't make up my mind whether to get an AGA-S or AGA-T+. I am also not sure if jumping in using mesh straight off is a good idea, or to stick with silica which I use for my Nova heads.
jeffc kindly sent me some links for AGA recoiling using silica, but the choice of atomiser is still not clear in my head.
Any ideas?
Andy

[chykensa]

Oops, forgot to ask this - could someone define a Genesis type atomiser for me please!
Andy

[jeffc]

Hi@AndyB.

Genesis atty, is an atomiser where upon you can use a stainless mesh wick for the juice transfer to the coil, or any other materials (ceramic, s/s rope).

Video details sent are on the AGA-T (W), models.

Hope that is now a little clearer.

Genesis was the name given to the stainless mesh wick system type devised by the German inventor: Raidy.
there is a long thread on ECF where he introduced the English speaking world to the concept and even
gave away DIY plans to make the very first, They were then made by groups getting together and paying
to have a batch machined. They were a great example of open source in action. Strictly speaking anyone
making a Genesis atomiser commercially is in breach of the copyright, Raidy only gave permission for his invention
to be used freely by the community for personal use.

Just a little update. I took the whole thing apart, washed it and left it to dry for a day or two. Today I thought I would have another go but this time I attached the tank to the Vamo and rotated the wick around the wire. I gave it 5 wraps and it is very stable at 2 ohms. Next time I am going to try 4 wraps but I am a bit reluctant to disturb things now it is working so well. Thank you everyone for your help.
