Just saw the question on the dual coils, I'm using 2.5 ohm standard smoktechs from Madvapes. I ordered them as the only thing I use is the 2.5 xl and didn't want to start over looking for something that would replace them. Got my BB in and started to set it up and found out that I should of read the fine print on the cartos, they're 36mm and not the 35 that the BB was made for. Wont fit. Checked in all my vaping junk and no 510 standard cartos anywhere, not even a black one I could pull the cover off of. Now I was starting to get seriously frustrated. Got nice new toy and can't use it. Ok, lets make the carto shorter, I own files.
A while later I've filed it down to where the tank will just go in if you hold it just right, filled it , primed the carto and tried this work of the machinist art. The draw felt like an ultra light that someone had enlarged the holes in the filter, all air no vape. At first I wondered about the carto as I had never used the short one before but it turned out that the only seal on top is DDs nicely machined surface on the brass insert and the straight factory edge on the carto. Back to square one as I don't have the equipment to shorten cartos to factory finish.
Lets take the tank out and look again, oh noes, once it's in the BB you can't "hold it just right" to get it out, the carto was just a touch to long. It took about 30 min of careful prying while using the correct vocabulary to convince it to leave it's home. At this point , after cleaning up the 5ml of e-joose I went in to watch a couple of hours of tv with SWMBO before I did something that I'd regret later.
Came back to my problem and realized that it wasn't a carto length problem, it was a to small hole problem as DD had designed the BB for 35mm cartos. That's when I started looking at the BB wondering if a little file work would cure my trouble. 15 min later the dual coil dropped in like the BB was made for it, all I had to do was file a small section out about 1mm deep and everything started working just like DDs video. If it works I'm posting a picture of where I filed it in case someone else wants to mod their BB the same way. I am careful not to over tighten the brass insert as I don't want to screw up the red seal on the bottom.
It has been working great since then, I even attached a lousy phone picture of it at work, it looks at home in a shop, just another one of my tools.
I even drop checked it once, turned around in the office and knocked it out of my hand, score BB 1 Drip Tip 0, think I'm going to continue using the cheap acrylic tips so they'll break and not screw with the BB.
Thanks DD for building something that just does what it is supposed to, looks good and will take the kind of abuse that someone who spends their time in places that are not the best environment for plastic will subject it to. The BB is a lot like my toughbook, made to be used wherever you need it to work without complaint. If you want me to, PM me and I'll mail you one of these damn overlength cartos to play with.
it's not showing as processed anywhere ....
