Boy can I identify with that. I am very close to just loading my flask with Kanthal and call it a day.![]()
If only it was that easy.... good luck getting it to work with Kanthal too

My flask has had some problems but I've now retired all my attys with nickel... It's working fabulously for me... Tons of flavor

I am about one more day away from retiring my Ni200s also. I just want a good vape with a modestly easy build.![]()
I'm gonna try a tad more. I'm a fairly patient fella, and I expected this to some extent when dropping the dough and being an early adopter. I'm just surprised at how poor the user experience has been. IMHO, the chip wasn't ready for prime time.

Reading all these horror stories have me less than excited to receive my rDNA now. They said it was a small number of boards that have the issue but itseems much more widespread than first thought. :-(
I may not be an expert, but I've done a lot of experimentation with the dna40 and nickel to find the things that work best. This is easy to see for yourself. Turn tp off and blast it with enough wattage to glow the coils brightly. You'll see what looks to be something boiling on the surface (despite the coil being dry in the beginning), and then the formation of small black beads the adhere to the surface, no doubt carbon deposits. If you just slightly glow then this isn't a problem.I wonder if this is really an issue in our application? I've tried to research it but found little comprehensible information. It seems that high temperature will cause embrittlement (loss of ductility). It appears to be used in many mission critical high temp industrial applications like nuclear reactors but our little coils are not stressed.
I found this Nickel 200/201, Nickel 200, Nickel 201, UNS N02200, UNS N02201 - MEGA MEX
A couple of highlights
" Typically, the elemental restrictions of both, nickel 200 and nickel 201, are combined into one, dual-certified chemistry resulting in a single alloy with the desired characteristics of both alloys, Nickel 200/201"
"Nickel 200 & 201 are approved for construction of pressure vessels and components under ASME Boiler and Pressure Vessel Code Section VIII, Division 1. Nickel 200 is approved for service up to 600° F while Nickel 201 is approved for service up to 1230° F. Melting point is 2615-2635° F."
I think I will assume glowing these coils is not a problem in our application. I have no qualifications to support my assumptions, I will hope an expert will offer an opinion.![]()
Oh when it's glowing brightly it's hitting way above 600. With a balanced coil set for 600 it doesn't glow. When glowing brightly it is probably hitting way above 1000 to 1200I would guess that with TP off, the coil may easily hit 600° F plus when pulsed to glowing. Personally I'd almost bet on it, but I'll wait until Phil gets his $4k FLIR camera aimed at it before I put any money on it.![]()
Just rewicked the dual hor BIG Fogger.

Not quite sure if we had this discussion here or in the other thread, but I got my Aris RDA today and it actually has small pins / tubes inside the posts that create a "platform" for the through post holes. So the screw doesn't easily cut the wire but clamps down on it. At first I was "... is in there?" and then I was "Oh look what is in there!". For my first build this worked fine, I could tighten the screws without anything snapping. So the idea of simply using stainless steel pins / nails and cut them to size to drop them in should work fine.
The Aris RDA itself is a beauty with gold plated posts and a pyrex glass top cap and internal airflow - no leaking. The airflow itself is rather tight but luckily enough for me (about the same as second airhole on Magma half closed). The airflow comes out of a center post to the left and right so I'll have to fiddle with builds.
I've made AWG30 dual contact coils with 11 wraps ID 3mm, they come out first at 0.09 ohm then 0.08 ohm and now at 0.07 ohm which makes them highly suspicious. It should be something like 0.12 ohm so probably the contacts do reduce the resistance. Upon initial dry fire the leg started to glow even with TP on and subsequent firing didn't produce any glow.
350,
If that is the BIG fogger it sure doesn't look as big as I was hoping it would be. The build deck look like my normal size Fogger.
By the way what resistance did you come up with total? My calculations say you should have a total of 0.05 ohms on a 3mm mandrel, 28 Ga.![]()
Just received my DNA40 Vaporshark! Yea, baby!!!! Coiling with Ni200 tonight!
