Well, first build was meh, burnt hits abound etc.

Maybe 10 or so builds later and it was finally getting close...but disaster struck and it got knocked over and alas she was hot-spotting' again.

I'll try again tomorrow, but my clearos are holding for now. Please tell me nirvana is on the horizon and that it's worth all this!

I'm wrapping 32g Kanthal 3/2 on SS in an RSST, thinking about trying out the 30g. Running this on a VAMO and a Twist-style battery. First wick or two wasn't solid enough, most recent one is really starting to wick pretty well. It's broken in now, so I've built a bunch of coils on the same one. I'm guessing these wicks can last a long time right? I was more just posting about the frustration of it all though...

Wait... How do you get hotspots on an RSST? Contact points are insulated...

Kink in the coil or too much tension on the coil or the coil touching the wick in some spots and not others, or the wick not oxidized enough at the coil end, etc. etc.

The RSST doesn't eliminate hotspots...it just makes them less likely.

3/2 is a little low for my taste right now.
if it tastes burnt, hot spots maybe from coil being too loose.
maybe your s/s isn't oxidized well enough.
maybe you're trying to cook it too hot.
try turning it down a little.
I'll try a little tighter wraps this time, should I try 4/3? I've heard 30g is more stable, maybe I'll try 4/5 wraps of 30g. Pretty sure that SS is oxidized nicely. 4.5 volts sounds too high?

Okay, here's another ~1.9 ohm 32g 3/2 wrap:

I always have a hot leg (this time it's Neg., but it's usually on the Pos.)! No matter how much I pay attention to tension, how much fiddling/poking/prodding etc. Sigh.

a suggestion i was given, that i've found helpful, is to wrap your coils the other way. in other words, your wrap starts on the outside of the wick from the neg, try starting it from the inside.

note: coil on left is wrapped like yours. coil on right is wrapped as i stated above.

Thanks man. Had to re-read that a few times before I realized that you are not doing the S shape. Mine starts on the outside, but ends on the inside.

Success. I just kept messing with it, and even though it looked like that bottom leg was still a little warm, I filled it up and it seems to be working again. Still not "perfect" but this is at least as good as the last build. Thanks for all the help guys, I could never do this without you guys.

PS how in the he11 did anyone figure this out in the first place!? Thank the Flying Spaghetti Monster for all those pioneers who got us here.

One thing is for sure, you are going to want to bring your leads in from the other side of the screws. Meaning, yours are coming in frm the LEFT right now, at least the POS. is. Now, when you tighten that POS. screw you are feeding coil back to the wick, i.e. loosening it. Always fasten your leads so they come around from the left, so it tightens slightly.

i believe we owe that bit of engineering mastery to none other than Raidy. that dude is an absolute mastermind. ECF search for "all my mods" if you havent already. it done blew my mind.

Thanks System, but this is on an RSST with a spring-loaded positive capture (no turning).

Kemosabe, I actually saw someone mentioning that thread (might have been you) and started reading through it. So cool to see the genesis of the Genesis.
