Man I'd LOVE to see how you built and mounted this! Also what did you use for the coil?

After pulling my original Ti build & throwing the stock coil back in I wasn't pleased with the ramp up @32-35 watts. I did another Ti 26 awg build this morning. Same build spaced wraps @.23 Ohm's & then put it on my SMY Mini 60TC, wow! The Bachelor cranks! Put it back on the RX & meh, played with the TCR which helps. Anyway, the point is that there's some serious mojo with the Bachelor. Stupid simple to wick, in fact I can't see how it could leak it's so easy. Tons of dense vapor & great flavor, total win on this tank for me. Next I'll try a twisted SS & a twisted K1 build but I'm pretty pleased with what I have so far. FWIW I ran the stock coil up to 80 watts last night with no wicking issues 
FT sells replacements. They say it is 31.1 x 22

Not impressed with this rta. Does not work on ANY of my mods. For some reason my 510 is way too short, so it will not fire on any mod I own. I ended up shaving down a bit of the insulator and it did fire only on my sigelei fuchai, but this thing leaks like the dickens. Woke up to an empty tank and my fuchai ruined, and I guess it leaked through the 510 pin. In the garbage it goes 
Doh!
Thank You. I should have looked there 1st.
What I'm wondering is If I tapped the Threads farther up the Chimney Tube, and then Cut the length of the Chimney, could I make a Bachelorette out of this Bachelor?
Of course, I would need a Shorter piece of Glass.
I wonder if a Subtank Mini glass has the Same I.D. as the Bachelor?
Yep. Now with a KGD rewick it sustains 30W @ 360F on 100VG. When I say sustains, I define that as the DNA doesn't start flashing TP message including successive chain vapes. So power may dip while vaping but it never goes zero. Which is quite stressing and the method I always use when trying new builds for consistency of comparison. Up the temp, reduce the viscosity and it can sustain even more power. Though 24W is kind of my preference. Even with lowering the nic, 30-40W is just too much vapor for me. Above 40W and I start gagging and coughing even with no nic.
As soon as I saw it I planned to build it like that because its how I do the Rose
I could have bet on that! I started using verticals with Foggers and Kaisers.Mounting is easy. Just make sure the leg coming off the bottom is attached to the positive through hole and the last coil wrap is flush with top of chimney. Bend the legs with needle nose pliers or a flat blade and your fingers. Wicking them with Rayon is easy in concept but a little more time consuming then a horizontal build.
Rayon: Just pinch and end to make a tail, thread it through the space between the ground coil leg coming off the top and the coil and wrap it like an enchilada. Do two of these, one enchilada at the bottom of the coil and the other at the top of the coil with the ends going through the juice channels. First vertical build was with Rayon because it was handy. I prefer KGD on coil center builds so I've since re-wicked it with KGD in a simple coil sandwich. Which is a lot easier to do. No threading necessary.
KGD: One layer either side of the coil with the ends of each layer pulled through the juice channels. See-saw the strips back and forth through the juice channels so they bottom out then cut almost flush with chimney top and trim sides. I like the wick ends inside the build deck even on wick center builds. Trim as close as you can on the sides then gently form the wick ends towards the coil inside near the legs/juice channels until the ends are flush with the inside wall and blow on the ends. For making the strips, I take a pad, strip off both outside layers and fold the pad widthwise ie along it's length two to three times. I like three layers if using a 4mm coil and four layers if using a 3mm coil but it depends on pad thickness. You want the dry cotton to conform to the sides of the coil. Making the strips thicker helps with this but I don't like them packed in. PG liquids may need the cotton packed more if they leak. But over night with this build and 100VG no leaks and that was with the JFC left open.
The KGD sandwich build is sustaining 30W @ 360F. Coil is 4mm diameter, 24G Ni200, 8 wraps, .07. There is some tweaking with the wicking to get it to apply firmly around coil, all done while wick is dry. I'll make a video later if you like.
Roxy and others may know better methods.

Measuring the spare that came with it I get 22mm on the nose outside diameter, 19.1mm inside diameter, 31.2mm length.
Or just wait for the nano version or clone.
thanks @350ZMO. I'll be using rayon for sure, and yeah that build does look easy now that I have "awake" eyes in it

If memory serves me correctly, I believe that a Subtank Mini uses Glass that has a 19.1mm ID. And I have some that are 20mm Long.
Yeah... I'll probably get a Bachelor RTA after the Holidays. And who knows? Maybe I'll try doing a Cut Down on it. Or wait as you say for a Nano or Clone.
I Like doing things like Tapping Treads and MOD-ing RTA's. I just don't like to Grind Glass. It just makes a Big Mess.
Finally! Now if only it can make it out before or during the holiday...
I found the best flavor for me with ss304 spaced clapton (0.40mm/0.20mm) build, boosted with 60W in tc modus. This runs well on the VTC Mini or the rx200.
On the Balrog, that is missing a ss mode, i run a 0.39mm Ti/0.20mm Kanthal A1 Hybrid Clapton at temp ti mode. 50W with Sensitivity 15 provides immediate vapor.
The taste of the Bachelor is the best i got from a mtl RTA so far.
btw. the Subtank Mini glass is about 2mm shorter, the other dimension are the same.

Vertical is the way to go with this. I've ran 24 & 26g horizontal kanthal, 36/26 claptons
I think you'll like it running vertical. I plopped in a 26g nichrome 80 with 3.5 i.d. and it raised my eyebrows. No comparison to running horizontally. Dense juicy vape. A little cooler than I'd like since it's 3.5 but the air flow is massive with the verticle compared to horizontal. .As soon as I saw it I planned to build it like that because its how I do the Rose
I hadn't used them in a long time but these coil cup designs work well with Vapin Donuts. I put two 1.5-2ohm donuts in parallel. Vapes great at 40W.
I used a hammer punch that fit the build deck and a hand leather punch to make the KGD donuts. You can also use Rayon.
Bend the legs over the sides of the donut and down.
A 3mm mandrel fits the vapin donut holes.
Think of the build as a double decker sandwich. Put a wick donut on then a vapin donut then a wick donut then a vapin donut then a wick donut.
The Vapin Donuts do have a TCR, I'll have to do more testing to figure it out.
Dunkin the vapin donut in mineral oil and measuring resistance and temperature with a thermocouple the TCR calculates to ~.003 in the vaping range.

Alright, got one in from eciggity since FT was taking forever. Just tossed in a plain ~3 mm spaced horizontal NiFe build for a base test... and so far very impressed. Really amazing flavor for a single coil build.
When the one from FT arrives, I'll try the vertical build.

This would be such and awesome tank if it was a bit smaller. Wish they will make a nano version!
