Ok, round three with the stainless mesh.. I've found what seems to be a good compromise after experimenting with several versions of the #400 stainless mesh wicks. Last I reported, I had been able to make a stainless wick that performed well by oxidizing but skipping the juice burn. Unfortunately I spoke too soon as by the middle of the second tank of a medium thickness juice, it was flooding and leaking..
So.. I made a new stainless wick, triple oxidized it, carefully unrolled it and inserted a single 1mm strand of silica wick inside. I had a couple inches of it from an old Blu disposable I had disassembled. I tried a few versions.. Wick hanging out the bottom and top, flush on both ends, etc. Long story short, the wick that performs well for me, provides great flavor, low draw resistance, and is still going like new after three days hard vaping is as follows:
#400 food grade stainless mesh cut at 32mm x 6mm to start, rolled on a SMALL paperclip to give you a cylindrical wick that is 6mm tall (will need to be trimmed shorter to fit later) gas flame oxidized and quenched in water four times, NO juice burn after oxidation, unrolled and a single strand of 1mm silica in the core cut flush on both ends and even more importantly, after much trial and error, the top of the wick must be cut off at an angle and sit exactly flush with the top of the spike when the bottom gently makes contact with the coil.
Some of the how-to vids I watched stated that the top of the wick could be cut square and be protruding from the top of the spike by a mm or two.. I can tell you it makes a difference right down to the last drop if the wick profile matches the height and angle of the spike. If you leave it sticking up it will flood. Anyway, I'm going to stick with this design for now as I'm quite happy with the performance. It's a lot easier to do than you might think and can be ready to go in five to ten minutes. The single strand in the middle is not my idea. I read somewhere in the forums that someone else had tried it. I'd gladly give credit if I can find that posting again. My apologies to the OP. back to cleaning and maintaining.
