My hydroxy generator.

Here is the current setup but I am going to redo the terminals and have them mount directly into the main body instead of the cap.  I have also had problems with the cap leaking so I'm thinking of maybe caulking it on and adding a smaller fill plug.  Both end caps are just pressed on with no glue and dont leak.  Unless I run into a problem with that I am leaving it that way incase of a back flash.



Here is a closeup of how I did the plate connections.  Just cut the corner off of the plate alternating between the left and right corner.  Then I drilled a hole for the ss bolt and jam nut every plate. You cant tell in the picture but there is a nut on both side of every plate to make a tight connection.  One side is pos.  other is neg.

so what kind of production are you getting with it? how big are the plates?

I also found if you shrinkwrap the conductive straps coming off the cap it stop stray electrolysis and heat.

I WAS only getting .5 lpm but that was at a cold first run.  My wire was small and gets hot.  And I have had a hard time sealing the thread on the cap and I believe it was leaking during the test...  The production has upped alot with few simple improvement.  I havent ran a test lately.  I bet it has come close to doubling that but I am just guessing.  I just tore it down to redo the terminal setup or I would run the test again.

Forgot the size question   I had to cut every side of these plate because it was a big sheet.  The width is about 2-2.25" and the length is 19" on the longer ones and I ran out of that size and finished with the 3-16".  I decide not to cut the 19" to 16" because it really isnt bothering anything.

Those screw on caps are nothing but a pain. I wrapped mine with what I think was a whole roll(not really) of ptfe tape to stop small leaks. The tape also made it tolerable to unscrew the cap later on. Some guys are using large o-rings to seal the cap. When I screwed it down to the o-ring I couldn't get the cap to unscrew later.

Just from a quick look at the close up I'ed say your plates are not very flat... Consistant spaceing is an absoulte MUST on a good produceing cell other wize you get pooling of the electrons
at the closest point and the parts inbetween do nothing...
think of it like a capasitor if you have an air variable capasitor and one plate is bent out of alignment the entire capasitor takes on the bent plates characteristics...and obviously its capasity drops... the same thing happens with plates of any size Large or small...
and another thing I might point out is the bent strips are too close to one another and should at least be wrapped in black tape to stop water contact for the same reason as above...
...I agree with you that the diference in length probly doesn't make that much diference...
but flatness between the plates and Keeping them that way is a MUST for good output
...
Here's an example of what NOT TO DO....
My very very first cell useing tin stove pipe that I never even tried to hook up to power I was so discusted with it...the spaceing is way too wide,the plates rusty o'l tin, in general a very bad start... so I took it appart and used the base for another try...but the plates were thin, so thin that they were warping when tightened down upon... I realised then if I were going to get any kind of consistant spaceing the plates had to be thicker.
but I used normal steel again to my down fall... normal steel just doesn't produce nearly as good as stainless steel does... for reasons unknown to me ... but it don't!
...
Now my question is, How much plate area do you have and how many amps are you testing it with ?
the plate spaceing looks about 3/16" to 1/8" is that a good guess ?

In contrast, here is the same consept revised later and look at the diference...
in the first pic the plates are thicker than before and closer togather but still very far appart
....
in the 2nd pic the plates are as close to gather as the oil-can-plastic insulators would allow...
the stack reduced to very few plates instead of the 24 or so I had before...
Oddly enough the 2nd pic...the short one, Out produced the bigger one hands down...
I got something like 1/4LPM from the big cell and something like 3/4LPM from the short one !
....
Oddly enough its not the number of plates but the way they are used that is the key to produceing good Hydroxy gas !
... I am quite confident in saying with just 3 plates +-+ of large enough size you could produce as much or as well as any fancy design....
....
thats my view on it FWIW...

I read that somewhere and understand.  Its no 100% but it isnt as bad as it looks in that closeup picture.  The plates arent lined up and are sorta staggered side to side making it look worse that it is.  I need more nylon bolts to help hold it better.  It is pretty long.

The spacing is 1/8".  My amps are unknown but under 25amp max power inverter.  I havent used any electrolyte yet.  Just well water.  I know, its still the beginnings of the build... still need some ammeter,supplies and such.

[Bob]

Ahhh... well thats good news I was hopeing it was flatter than it looked ! HAHAHAHA
the KOH or Lemonaid Koolaid will make a hudge diference in output but probly even a small amount will over tax your powersupply....( that's allot of plate there !)
...
I tested mine with a 10 amp battery charger on a good truck battery...
then found later that my battery charger wasn't chargeing worth a darn...
borrowed my dads charger and used it with the same results... gave up and put it on the truck anyway
and I am glad I did ...it works better on the truck then it did on the bench....well it DID...anyway
it got dirty and all that ... but working good now!

I got this info from another forum. I thought it was a good idea of how to seal those screw caps. He said to cover the threads completely with wax from a wax ring. It makes it easier to seal the cap and unscrew it later.
