I use a screw or a drill bit.. :)

A small nail works pretty well, as it will typcially have the nail head you can use to compress the coils if necessary. I even saw one where someone was using a paperclip. Jeez. I've tried a few different things, but as I noted, they don't seem to improve performance that much to me.

They are micro coils, that I wound myself out of Kanthal. I've the single one is on an IGO-l, and is right at 1.3 ohms. It fires great on my P+16. I have various wire sizes I'm playing with. I work as a Substation Operator/Electrical Maintenance Journeyman on the Bulk electric system (thus my user name)

I've also been winding standard coils, and rebuilding the heads in the protank2. I'm using high quality Fluke digital RMS multi-meters to verify resistances, and have had really good results hitting all my target ohms.

Like I said, I'm new to the vape world (about a month in), but totally hooked on the DIY and fine tuning aspect of the hobby.
I'd be more than happy to build, and test whatever spec coils you'd like (and report the results with various liquids) I live close to Ahlusion, and a B&M that carries various premium liquids. I'd be happy to purchase a Simplicity to use as a test platform (been wanting a good mech with more battery life) I do lots of testing of electrical equipment as part of my job (but on a much larger scale, 120KV and up).

Those coils look like ribbon wire to me. Micro coils are just like other coils, they are just wrapped on a really small instrument, like a tiny screw driver, with the coils very close together. Some say they give better heat retention, flavor, etc. To me they seem to work very similar to regular coils, i.e., I can't tell much difference myself.

No ribbon wire, just been using 28 and 32 gauge kanthal.

To me they are fast and easy to make, and very consistent..re-wicking is also super fast and easy. So if I want to swap from a strong aromatic tobacco to a light fruit flavor, I just pull the cotton, heat the coil, and put fresh cotton in. Start to finish is about 2 minutes or less to build and replace a coil.

I should mention, you can do 4 coils too very easily on our design if you want. Seems a bit excessive to me, but hey...I think most will be sticking to one or two coils on it, but feel free to experiment, that's what the testing is for :)

Dang! I have a feeling this little motor scooter is going to be pure saaaaaaaaaa-weeeeeeeeeet'nes!

I hope I didn't come off as critical. They certainly do work well, and in fact I have them on most of my current setups. I just don't go the ultra-tiny route that some people take (and it doesn't appear that yours are super-tiny either). I agree, they don't really take any longer to make or require any special effort, other than having something to wrap them on. I always pre-wrap my coils on a screw driver anyway. I use cotton, too, so I always install the coil before inserting the cotton. I used SS wicks for a long time, but since discovering cotton, it's all I use. So easy to replace, great wicking, great flavor.

This baby was designed from the ground up and purpose built. I think most will really like the innovation and ease of use it brings to the table.

I should mention, we finished drafting the final design last night, should move on to the working prototype early this coming week and I hope to have them in testers hands in about a week. We'll keep you updated.

Let me be the 1st to congratulate the testers who are selected. Do David proud and put that thing through it's paces so he can make adjustments and fine tune the final product.

I have faith that whomever David chooses will do just that!

My only request is this... Make it fast because the world awaits the Super T RBA!

:thumbs:

I didn't take it as criticism...any feedback will ultimately help me find what I like best. That's one aspect I really like about this hobby, learning.

I've been trying various diameters, my current one is small, but not ridiculously so, easy enough to change wicks without tweezers or anything, but not so large that I sacrifice surface area for increased resistance. I have some different wire inbound to play with. Right now my goal is the best balance of vapor production, flavor, and battery life.. I don't necessarily need to make huge clouds, just as long as the vape is satisfying. So far so good, and I'll be doing more experimenting over the weekend.

If you haven't tried it yet, try to get your hands on some 26g or 27g. 26g is significantly thicker and is more difficult to wrap. It was definitely too LR for me, but I found that the 27g was great. For me, a coil diameter of 0.6-0.8" is the best compromise and I shoot for 1.0ohms. Anything smaller in diameter and it seemed to choke the wick too much. I'm a cotton wick user as well.

I'll definitely give it a shot. So far I've selected a wire, used my meter to get an idea on length for my desired resistance, and choose a diameter that will give me a decent amount of wraps. I wrap, heat, test with the meter, install, test again, then I'll test fire with a fresh cell to verify that it heats quickly and evenly from the center out. If all is good, I wick it and vape. I'll adjust air hole/coil positioning until I find the best spot, and call it good. It's fun to play with for sure...I just need to get a second mod so I can vape while building and testing coils!

I'm a total stick in the mud. While I don't mind tinkering and experimenting, it's the last thing I want to do in real life. I want no thought, no time, the absolute minimal amount of personal involvement.

I agree with you there..

But sadly, most RBA/RDA require tinkering..

I absolutely love the Diver but loathe NR-R-NR wire setups..

I hope David's RBA makes the tinkering aspect of most RBA's a thing of the past..

Wrap a coil, slap it on, vape away! Now that would be nice!
