As per eratikmind's post, my next step in my struggles with this confounded Zapper and nickel NR wire is to move to silver crimps to join R/NR, and shift to silver NR wire in the process as well. The silver should be more malleable, and therefore get press-fitted better when inserting the ceramic. Alternatively, using much thinner gauge NR wire might do the trick.
Admittedly, my ceramics are a very very tight fit when inserted, which I always liked, since it eliminated any possibility of slippage, but this may also be leaving a gap for liquid to escape between ceramic and the interior of the Diver's cup.
Since you are a GP Paps fan, you know that manufacturing fault tolerances for such devices are minuscule, so a fraction of a mm can mean one Diver works flawlessly, while another needs a bit of... persuading to be optimal. You have hundeds of people enjoying the first batch of GP SnPs, while mine sits in ruins, too small for my Divers, and I await my replacement. For every Diver comment about leaking, there are dozens or hundreds of others we never hear about, that work flawlessly.
One interesting test I might run is to build out my Scuba Diver with a normal wick setup (not the spiral), but not pass the lead up the outside of the ceramic. It will not function, but I can let it sit for a day and see if there is any leaking. if there is none, this should confirm that the liquid is seeping between the outside of the ceramic and the inner wall of the Diver's bottom. But I'm not doing this until my replacement SnP arrives, and I have another tank to use a Diver, because the Diver really is far superior to my Ithaka and kayfun for heavier tobacco/chocolate juices.
(and, yes, I talk too much, I'm Greek, our πολυλογία built Western civilization, you're welcome)
