RDA Vapor Production

[metallicafan2633]

Just two days ago I bought my first mechanical mod and rebuildable dripping atomizer in an attempt to become familiar with dripping for times when I'm relaxing at home. I hyped myself up a lot about how great the flavor and vapor production will be with my new set up. I built three coils so far; the first of which was a single coil, followed by a dual coil, and finally another single coil. The two single coils came to be 1 ohm and the dual coil was .5 ohms

Unfortunately, I'm really not getting the performance that I was hoping for out of this set up. The flavor is great, but i get less vapor than I do with my 2.4 ohm protank set to 9.5W on my vamo. I was hoping you guys could help me to build something with better vapor production based on what I have available:

The Natural mechanical mod
Optimus Rebuildable Atomizer Optimus RDA (Rebuildable Dripping Atomizer) $7.22 | gotsmok.com
3.7V IMR 18350 (x2)
3.7V 18650
80/20 PG/VG juices from mt baker (2 flavor shots)

Thanks in advance for the help, I look forward to learning a few things about dripping from this thread

I cannot get a clear shot of the inside off the web anywhere, but if it really has 5 airholes this would be the problem. with rebuildable drippers and genni's the vapor production (when all else works properly) is directly related to the airflow making contact with the wick/coil surface. more air coming into the chamber without contacting the coil area leads to less vapor.
i love dripping and have a good dozen drippers from 5 dollars up to 100. and with slight adjustments they all make massive head spinning plumes.
i cannot see this design working very well and would say either try to cover the extra holes or figure out how to put the wick sideways so the coil is in front of all the holes.

thanks for the advice. ill go take a few pictures so you can see how airholes work, and maybe you can suggest where i position my coil next time i set it up. it does have five airholes drilled in, but depending on how you position it you can get use out of any amount of the holes, all five or none of them at all

Few possibilities i've encountered;
-Build? rat tail or ribbon?
-Amount of wicks used?
-How many wraps of kanthal are ya getting?
-Too many drips may cause flooding hence lesser vapour.

*DO not rest the coil on the base. have them lifted up before tightening down.

in this photo you can see the five airholes drilled on the side of the cap


the slit on the top section of the atty runs along the base section. the amount of airflow that you get depends on how many of the airholes in the previous picture line up with this slit


this is where my coil is set up, the air hole is on the right side of the atty in this picture

im not sure how much wick im using, but no more than 2 to 3 inches i would say. im also not sure of the difference between the rat tail and the ribbon build. im using four wraps of kanthal

Interesting. You're comparing a provari/protank with a natural/rda. Too many variables. Wrap a 2 ohm single wick with 32g kamthal for your rda, try it on your provari and compare to the protank. Then try both protank and rda on your natural.

Process of elimination. Is it the natural, your rda, or your build.

it kinda looks as though the coil is a bit far from where you say the airhole is. If this was a regular rba with a normal one hole cap i would, using the bottom picture for reference. put the airhole at about 4 or 5 oclock position to that wick

so next time i build the coil, i should have it sit further away from the posts, and closer to the outer edge where the airbhole will be?

in a dripper while the other people are correct about wick wire etc. the air has to pour in over that coil. to experiment take the cap off and fire it wet - it makes vapor but not a lot now kinda blow next to the coil it makes more vapor. now blow directly on the coil and look at the amount of vapor coming off.

if it still isnt clouding up the room it could be the mod not firing hard enough. but i have a natural, while not the greatest it works fine on low ohm coils for me. or something in the wick build. have to start eliminating things, if it vapes without the cap then its not the wick

when you suck on a tube the air comes in the hole and travels a very short distance before heading straight up to your mouth, if the distance to the coil is too far away. the air is in effect coming in the hole and skipping over the coil picking up a little vapor and thats it.

the idea is to force the air ON the coil to make vapor. not to mix air with the vapor.

awesome info thrasher, i really appreciate it. can you possibly post a pic firing your natural without the cap on so i can compare how much vapor yours is putting off?
