I actually made one of these the other day for a single coil rda, its been a good while but they are a great build
Sweet looking too. I've also figured out how to get stapled Claptons. I'm just not quite there yet. That'll take investment on my part both money wise and just set and do up wire. Sure, I enjoy doing up wire up to a point. Then, on the other hand I can be happy tossing in single strand Kanthal or SSL316, NiChrome.
Not sure I'm to artisan level well enough to start selling coil builds. And I'm not even sure there would be a market locally. I've seen some here in our apartment complex vape. We all get what we need however. It would be awkward, "Hey, want to look at my coils?"
There's two shops in Ripley. I'm sure folks visit the one that come out of Charleston & get coils. The other shop seems set up as a new vaper death trap. "Sure we got your gear, for all your money. Need help? Tough." So, really rather not walk into either shop with "Got coils if you can move them."
I would be lucky to see any return. "But you gave us the coils." No, I'm not making excuses but framing the realities of how things are. Folks get what they need however they need without bumping into the odd neighbor hawking coils, shops do for shops and won't let you consign sell.
Sure I might sell over the web. Then again it comes back to being that weird neighbor hawking coils. Besides that selling online then requires postage, shipping, insurance. I'd not have any idea of a fair price to meet all that. I see what others charge and that's okay. I'm sure some have built solid reputations and can charge a little more. It really still doesn't help indicate what some "new" guy selling could sell coils priced at.
That leaves me back at where I found myself as relates to programming. "Damn, I got no problem that programming can solve. Ergo, no real need to learn much programming." In this case it's coils. It's relevant for myself and for myself alone. Already figured I can do with the simplest. Life is frustrating like that at times.
