Micro Coil for the RBA on your REO

All I have to say is that you must have better eyes than I do, super-x-drifter. lol

One more thing. I have to think that ribbon wire is getting popular because it has more surface area. In effect, its making a thin tube with barely any gaps, in some cases nearly a solid pipe with wicking material passing through it. Seems a very efficient way to get maximum coil to wick contact.

The same would be difficult to achieve with round wire. Even with 28g Kanthal you would need an excessive amount to wire to create a solid pipe. Now if you reduce the diameter of your 'pipe' you can get a decent amount of length for your target resistance and still create a nearly solid surface to contact the wick. Enter the "Solid Micro Coil"

I am definitely ordering some soon. Sounds promising. Is the ribbon sharp - looks like it could slice ya like paper cuts when wrapping?

Not. I use an illuminated magnifying setup that I picked up at michaels.

Tho thread micro coils. Try a dental bridge threader. Its thin blue plastic line joined with a loop left open to put floss thru. Definitely thin enufff and skinny

Just ordered 50 feet of Kanthal A ribbon here for just under $9 shipped. I like that is coming from the US rather than international because it'll be here in 4 days.

Yes, solid micros may be the next big thing

Doesn't Kanthal D have less aluminum in it than Kanthal A?

From what I have read, yes. Kanthal a1 has the most.

Sorry about that. I can build a coil but can't paste a link! It is from eBay, I searched "Kanthal A ribbon wire". It's the one from New Jersey. I hope that helps! Here is another attempt:

I also updated the post above with this link since it works. Thanks Horselady!

Thanks, Russ, you just cost me more money. I'm gonna kill ya... and I'm gonna kill ya slow.

You can get a great deal on Kanthal A here too. Keep scrolling, they do sell in small amounts too.

For example: http://www.temcoindustrialpower.com/products/Resistance_Wire/RW0106.html

Has anyone had a bad experience with Kanthal D? I ask, because I spent a lot of money getting the heavy metals OUT of my body and it rather concerns me that I might be putting a bunch back in. lol. Aluminum is a bad one to have in your body. So, I'd like to minimize it where I can.

From my understanding, Kanthal A-1 is actually safer. Its operating temperature is higher than than of Kanthal D, 1400C vs 1300C. Both are a LOT higher than they need to be. NiChrome, for example is 1150C, but it's still very usable. If I understand correctly, NiChrome is what Cisco and HH357 atomizers use.

To rephrase -- I don't think you're inhaling any metals unless you try to breathe it while dryburning your coils until they pop (melt)

I believe that is the round wire. To my knowledge, temcoindustrial does not sell Ribbon?

I'm keeping your address this time. I hear banjo music....

Monday Morning Micro Madness

Here are two examples of microcoils built with 30 Gauge Kanthal A1 where the coil is so tightly wrapped that it is nearly solid. I found a very easy item to use as a mold - a needle tip juice bottle cap. It is slightly smaller than a paperclip - totally allowing you to throw another wrap on and keep the ohms low.This first example is the RM2 with 12/13 wraps metering 1.6. Very simple to do with a little light and magnification.

 

[super_X_drifter]

This is a chalice with with a 14/13 wrap metering 1.8.

So how do they vape? They look great by the way. Who needs ribbon wire when you can make a solid micro.

Nicely done sir.

Thanks Joe! The build in the chalice is on the VVG and it is perfect - I turned the power on it down a hair to make it so. The build in the RM2 on the grand is a little on the agro side, in that it sounds like a small rocket taking off (I also use a very short DT).

It seems that when you twist a coil that small, it may be necessary to build to about 2+ ohms to keep the vape quality in the "mature" range? I'm guessing that its because it is so small that it heats up so hot and rapidly that it makes for a very warm, animated vape? I would probably have dug it if I were about 20, cause its so loud, spitting and boisterous - damn rugged, if you will. But now, because if my vvg, I have come to prefer a more mellow vape. Nothing a few extra wraps couldn't correct I believe. I'm gonna rebuild it tomorrow with about 15 wraps. That should put it right around 2.

The vapor and TH are remarkable in both builds, just a little more "in your face" at grand voltage.

I think that a safe conclusion to draw is, the smaller and tighter you wrap your coil, the higher the ohms you want to target. With fat, non scrunched coils, i liked 1 ohm. With this tiny "wall of wire" I need 2+ on a grand. I'm vaping this as I type and the flavor is ridiculous! Might just keep using it!

My guess is also that the flat wire will perform similarly.

I just can't get my coils to stick together the way you do.
