Dropping in for a quick stop. Seems a bit quiet in here, but maybe some of the new BB owners are still waking from their nic comas ...?
Tip for the new and current Diver users: Hope DD won't mind the vendor plug, but Stormy's Vapor Cellar now carries what they call "Ready Wire" - pre-made NR - R - NR wire already assembled, in four resistances. You get 50 pieces for $9 - about $.18 each, not bad actually, and less than that if you can find a coupon. The join on them would be hard to notice if the NR and R wire were not different colors.
I recently rebuilt my Divers with the 2.8 ohm version and to me it was WELL worth the money to not have to mess with tying thin little wires together to make it work. These would also be great for Oddy-style rebuildables. I plan on trying them in the ScubaTube this weekend.
Another tip: I've been messing with "micro
coils" (you can look 'em up on ECF) in my RDAs and carried the concept over during the Diver builds. Basically, wrap those
coils right next to each other instead of spacing them out. Makes for a small, dense coil-pack in the center of the cup. You have to watch the tension so's the wick doesn't get choked, but get that right for whatever wick you use and it works GREAT in the Diver.
Yet another tip: Diver seems real sensitive to the length of the wick. Too long and the ends .... up against the tube, reducing wicking; too short, and they wick too much and flood more easily. I've taken to trimming mine just to the point where it feels like the wick is
threading into the upper tube when it's screwed on. This leaves a very small gap between the wick ends and the tube once it's past the threads. Seems to be working well but I still have to take the occasional priming puff. Next time I'm going to try just a smidgen shorter than that and see what happens.
Yet one more tip: Recently I started rolling up a bit of paper towel to about 4-5 mm in diameter and trimming it to fit in the Billet Box tank well, in the divot just behind the atty center pin. Just long enough to fill the gap in the back - NOT long enough to wrap forward around the atty of the carto (which would kill air flow ... but it might be something to try if you find the draw is "airy"). This ends up filling the air gap between the back compartment wall and the carto/Diver atty connector, and the bottom of the compartment and the tank. This serves a few purposes:
- As a diagnostic tool. If there's juice in the well, this will help tell where it's coming from. If the bit of paper towel is soaked, juice is flooding from the atty connector; if it's dry or mostly so, it's most likely condensate from the top and might indicate the need to tighten down the brass ring a bit, or for a better-sealing drip tip. I think.
- Not entirely sure yet, but as a side effect it seems to sop things up when it's just a bit of condensate and keep the compartment drier. At least, it seems to me that the tank is coming out easier whenever I change tanks or replace the carto.
- In an emergency, you've got a tiny little paper towel with you. If you have to ask what that's good for, Richard Dean Anderson would like to have a word with you.
