    Looks Good to Me. Kinda a Lot of Wraps. But if that is what you Like, that is all that Matters.

    Only thing I would suggest is Wrapping your Coil the Opposite Direction. That makes the Legs laying Flat with the Coil above it when mounted. Easier to Mount IMO.

    Check Out Asbestos's last picture in post #25 to see what I mean.

    How do you like 430 SS vs 316/316L?

    I normally wrap so that the coil legs are as you describe. They're only upside down because I wrapped a machine screw to get good spacing and unless you use a left hand thread screw, it causes the legs to be opposite of normal. On the SS430 vs SS316 thing, I can't tell a huge difference, but its easy to work with and it's TCR values are native to the mod. Both are really low resistance. I've got another spool of NiFe52 on the way and I think that's going to be right in the sweet spot. It's TRC is really good and it's got a bit more resistance.

    Gotcha.

    They are a Little Harder to Find, but you can get L/H Machine Screws Online. Not exactly make of break for something like this. But an Option.

    I've got some 430 SS coming on a slow boat. A Very Slow Boat it seems. I've never used any. So I was curious what you thought of it.

    On a recommendation, I started getting my wire from here. Very satisfied with the quality.
    Zivipf.de
    I haven't seen any one site that has the selection of wire they keep in stock. They've got odd sizes, shapes and exotic alloys on hand. My last order took about ten days to arrive.

    After watching the guy from Norway(or wherever) on YouTube hammering round wire and claiming great results, I decided to try it. It started out as 27 ga SS430 round wire from zipipf.de. I can't say it's dramatically better, but it's as least as good as round. 8 wraps at 2.5 mm i.d. came out at 0.55 ohms. After annealing and cleaning, it was easy to wrap and build. The added surface area is probably better suited to big cloud, high wattage use, but I'm gonna run it a couple of days and see how I like it. Even though the coils are really close to touching, it's working well in SS430 TC mode. Sometimes you get bored at work......

    @Don29palms knows where to find it already hammered . He uses rectangle wire, triangle wire......wire with unicorns etched into the surface... He's got a guy.....

    Thanks! If round wire was a 5, where do you rate rectangle wire?

    8. All I use anymore is fused claptons or rectangle wire. Well I do still use round wire for tc builds. I really like rectangle wire. I use the nichrome 80. The .9mm x .3mm rectangle wire is like using a 28g triple core clapton.

    They did. Thank you so much. I haven't used them yet because I'm trying to force myself to find an alternative solution. But I'm really glad I've got them. Thanks again

    So far the hammered/flattened wire is working well. I also have production rectangular wire as well as ribbon. My understanding is that cold forging the wire changes it's properties in a positive way. It's definitely more dense. Not exactly sure what that's supposed to do in the vaping arena. It doesn't spit back and it's staying clean even using Boba's. I didn't see any big change in resistance (assuming similar size/number of wraps). I guess its just another relatively useless bit of info to rattle around in my head.....

    I will when I get home tonight. You want pics of the rectangle wire?

    Cold Working many/most Metal Alloys tends to make them Harder. But with Hardness come Brittleness.

    It's like when you go to Bend the Copper Tubing for your Frig's Ice Maker. You can Only Bend it Twice. But if you bend it a 3rd Time, it will Break.

    But if you Heat the Bend with a Torch and let it Air Cool, you can Bend it Again (Twice) without it breaking. This is a Good Example of Work Hardening and then Annealing.

    A Cold Rolled Rectangular Wire (non-Annealed) could/can exhibited the same thing. Harder that Hot Drawn Wire. But More Brittle.

    Would any of it Make the Hit you get any Different? I dunno. Probably Not. But a More Brittle Wire would probably be Harder to Wrap.

    BTW - If you Dry Burned a Round Wire which was Hammered Flat, whatever Changes to Hardness/Brittleness would probably completely revert back (or perhaps even Less Hardness/Brittleness) to the Round Wire sate.

    Because the Dry Burn / Air Cool is essentially Fully Annealing the Coil.

    I pretty much came to the same conclusion.
