Frustration

[Shawn Hoefer]

Spent about 4 hours trying to put a good coil in a DID clone. Had a good coil in it before, so I knew it could happen. The _!!'/-÷*=,='%'÷÷, £'€%"% top leg would not level out... hot hot hot. Any thought on why?

I finally gave up and built a largish micro-coil, and threaded the wick through, but I'd still like to know why...

Some actual info on the coil and or wick materials might help.. If mesh could just be a tight wrap, resulting in hot leg.

400 ss mesh, burned about 8 times, 32 ga kanthal a1, 5/6, 1.5 target (came out a wee bit high)

Could be a tension thing, I've had hot top leg before when I've either ended up pulling the top loop of the coil too tight or if the leg leaves the wick at an angle and has to be pulled up to reach the positive post. Only other thing I can think of would be that the coil is shorting to the mesh, but it sounds like you oxidized the crap out of it and had it metering correctly with the mesh in so that's probably less likely.

I've ended up with a hot leg I just couldn't crack before, ended up pulling out the coil and trying again.

What the egg said.

Also 32 awg is very thin and has a tendency to "dig into" the wick more than thicker wire. Also it snaps so easily I couldn't get paid to use it on a regular basis

This is not me lobbying for you going sub-ohm or chasing clouds or anything. It's just that on gennies you may find it easier (and better?) to use a somewhat lower resistance and thicker wire. For me, gennies didn't really 'click' until I tried setting up one with 28 awg. I may use thinner wire, too, but no thinner than 30 awg.

I had a similar experience with wire gauge as well, had all kinds of trouble with 32 awg and didn't really have gennies "click" for me until I tried coiling with 28 awg. I typically run mine at around .9 - 1.6 ohm depending on the atty. I've also found that I typically like using a higher power with gennies than I did with things using other wicking materials, maybe due to the mesh acting as a heat sink of sorts...?

I've successfully gotten things up and running using 32 awg since then, but have found that I would either need a regulated mod to push a high voltage to it or would have to use so few wraps that the performance isn't great.

On the other hand, I've been pretty happy with 30 awg in some of the smaller chambered gennies like the Sat22.

32 kanthal is pretty thin, and moves around easily under heat. I ended up with 26 kanthal and a 5/4 wrap for .7 ohm and it stays put. On my RSST it heats from both ends at the same time, (insulated wick hole) and I've never had the least problem with it. Glows nice and even from the top of the coil to the bottom.
