1/16 vs 1/8 gasket and electrolyte
alright guys i have some questions for you.

so i have tried pvc sheet as a gasket in a drycell and that did not work i had leaks all over the place and its 40mill my plats are 16ga which is 48mill so i'm thinking that’s to thin. the first time i tried it out i was getting a bubble ever 3s or so, with lot of leaks Mad

give me your $.02 on what you think is the best to go with.

which is better to use 1/16 or 1/8 thick Neoprene gasket?


theres all kinds of electrolytes but is KOH the best? i can only find 90% pure.

There is a couple of builders that just changed from 1/8" to 1/16" gaskets. Here is a post from one so far.

RE: 1/16 vs 1/8 gasket and electrolyte
The "ideal" plate spacing is supposed to be 3mm (.119"). The last cell I built I used 1/16" vinyl (from McMaster Carr) and doubled it up.
The reason I doubled it was because the vinyl sheet measures .060"...so, two sheets are .120" (pretty close, eh?)
The Smacks Booster (the newest one) has .080" vinyl (also available from McMaster Carr).
I did build one cell for a friend using 1/8" neoprene. It worked quite well, in fact, it has never leaked, even after being frozen a few times.
Neoprene is more trouble free, but vinyl is cheaper.

RE: 1/16 vs 1/8 gasket and electrolyte
Howdy! I'm back from the grave everyone, oooo spooky!!

Well first, my dry cell is made with the orange-red colored plumbers pack gaskets, which are VERY effective. It's 1/16" gap, and with the Lowes plates, they shorted so I doubled up to 1/8" for the gap. My electrolyte is maybe 3tsp NaOH per quart distilled and I'm pulling around 3.6A if I remember. Yeah, that's not much, but it's producing around .4LPM! That's pretty good for the amperage, but no matter what I tried (6 plates, +nnnn-) I couldn't get above 5A hot (TONS of NaOH added). So I decided screw it, 3.5A with .4LPM is good enough until my next build, the 4 gang wall plates of DOOOOM!! I still need some cool acronym for that cell so I can engrave it, like my LDC III. Any ideas are appreciated lol!

So yeah, long story short, I'm converting over to using car tire inner tubes (new, NOT used for dirt, etc.) which can be obtained at Big O or Discount Tire for $10. They give you PLENTY of gaskets for the price, too! Great deal IMHO. Smile

You mean a caliper or micrometer?

RE: 1/16 vs 1/8 gasket and electrolyte
Most car inner tubes are less than 1/16" (.0625")(if you can find them) Truck inner tubes are .125" (1/8") unless they're cheap Chinese inner tubes, and then they can range anywhere from .060" to .110".
Caliper or micrometer, I've got both...
