The threaded rod electrode was my first design, the plates are my second. The threaded rod design seems to produce alot more bubbles with the exact same electrolyte amount as tried with the plate design. I don't have my amp meter at the moment so it could be that the way the plate design is it draws less amps than the thread rod with the same electrolyte. So i think i need to try both electrodes again, adding electrolyte to get a fixed amp draw. Then with both electrodes pulling the same amps THEN i will know which is producing more. I have not yet figured out amp draw and production changes with surface area, thickness, length etc for the electrodes. I do know that production and amp draw are affected by the way the electrodes are set up.
Still trying to research more into "Series" and "Parallel" designs and weather or not to insulate electrodes or to use neutral plates or not.

Sorry this forum doesn't resize pictures for you, i will post pics later,
