The Infamious "RANDY CELL"

[Bob]

I know Randy is a busy man and hardly has time to get on and post some times so I thought I'ed post his
plans for him.... he can critique it later !
...
 From the Beginning this cell started out as 22- 2.5"o.d. Stainless steel fender washers...
and although the cell had more plates and bigger diameter the results were a bit less than the Mark I
cell that he later drew up for everyone...
 his larger cell put out 1.75LPM at 20amps if I remember right  and I discussed with him my findings on tuning the cell to the amperage given by removing plates,as I did on my first cell and actually got the
LPM to raise !... in the mean time he made more washer cells but couldn't find the 2.5" fender washers so he settled on the 2" ones that were readily available.
 This guy set up all night with his freshly built sell testing it in his coffee cup !  then removing a single washer/plate and testing it again....
He emailed me the next morning and said that HE FOUND IT ! 11 washers is the perfect number and be sure that you start and end with a positive washer ...that's very important !
I was making one at the time and so I went out and removed 1 washer from my cell as I had stopped at 12 washers because my previous tests suggested that somewhere between 8 and 12 plates was the best for 20 amps...
 He was Dead on it ! ( as this guy usually is!) and the cell I made put out 1.5LPM and would fit in the palm of your hand ! ... but his cell put out 2LPM... due to his meticulous attention to detail no doubt!
weeks went by with him tweaking the cell and fine tuning the spacing and making more of them
then he anounced that he had 6 cells all made up and was going to hook them in series and see what he got.  At the time He and I were both learning how these cells work and totally underestimated the amps they needed to run ... but that's another story and I'm getting off the point...AGAIN!
... THIS Cell, I Dubbed the "Randy Cell" is explained in his single paper/pic shown below
the Mark II version of the "Randy Cell has neutral plates in it and is also shown below and its output is even better than that of the Mark I version with a Whopping 2~4LPM at 20amps, However the output was inconsistent... it varied every time he tested it....it never would settle down.
...Plate spacing is extremely close on these cells so don't believe everything you read about close spaced plates will trap the hydrogen bubbles... it doesn't!
when building these cells use all Stainless steel hardware and 2 pocket Nilon school folders as insulator material... the O-Rings can be purchased at most hardware stores where you get the hardware

Randys Inductive cell (Randy Cell MkII)
follows the same idea on assmebly but with a insulated washer between each powered washer.
here's his Pic.

According to Randy the Mark II cell is too Irridiac to bother with...with the LPM output going up or down just about every time you hook up power to the cell... for REASONS UNKNOWN!
... He fussed with it for quite some time and finally gave up on it and went back to the MkI cell design.
...
  I have made 4 of these "Randy cells" Myself, and all work very well and after a bit of tweaking
I finally got 2LPM from each one... it seams that the close spacing is crucial to high LPM ( I had to torque mine down really tight in order to get the spacing down real close )
...
I have written a long section on assembling a "Randy Cell" posted below for your convenience.

Assembling the cell.


    If you think of it as each plate as close to each other as you can get..all spaced the same.... Then you'll get the right picture of making this cell.

its an arrangement like this +-+-+-+-+-+ 11 plates in series (at least that is the way we used to describe it)   but sense every negative plate is connected to the negative lead outside the container and every positive plate is connected to the positive lead outside the container it is actually in Parallel....electrically speaking.
every plate operates in this design the back side of the end plates doesn't do much of corse
but they are positive so the next plate a negative plate ( on either end) is surrounded by a positive plate above and below it... making the negative plate operate to its fullest potential. each negative plate in the stack of 11 washers is the same  and connected electrically to the same bolt... and INSULATED from the other bolt... they cannot make contact in any way...
like-wize the positive plates are very much the same but attached to the other bolt and insulated from the negative bolt...
so you have a big washer with 2 smaller holes in it the small hole is to the right and the bigger hole is to the left...  sense this is the first plate on the stack it is destined to be a positive plate...  a shim stock nut thingie, is put down over the right side small hole and then an insulator....
on the left side there is a insulator under and over the 3/8"hole and a O-ring in the hole
the idea here is to insulate the plate from touching the bolt at all !
the second plate , this one is a negative plate and it goes on with the small 1/4" hole to the left side over the side of the O-ring on the previous plate.... a shim stock nut thing is put down on it and an insulator... on the 3/8" hole now on the right side a o-ring is added and an insulator so this plate is insulated from the positive side....
the next plate is a positive plate so the small hole goes n the right side ....
and on it goes till all 11 washers are on there.... you then top it off with a extra insulator and a washer, or a insulator of some sort on the o-ring side and washer and a nut.
 and a washer and Nut on the 1/4" hole side... ( no insulator needed on that side)
... you then tighten the nuts down about 1 turn at a time on each side till they are both good and snug... but not real tight.... too tight and you will cut through the nylon washers so snug enough to bring all the plates to the same spacing  and thats that !
test the cell with a VTOM meter and check for continuity between the posts/bolts if there is any continuity you have to take it apart and fix it !
if no continuity then check each plate that is connected to that bolt all should have continuity that are attached to it .... and NOT the insulated ones....
same for the other side...
if you get it past those 3 tests its time to toss it in the water and make bubbles cuz its done !
 this small cell will put out 2LPM at 20 amps if you did every thing right... Randy has achieved as much as 2.7LPM for 20 amps if I remember right ( not positive on that)
but even I have achieved 2LPM at 20 amps !  so if you get that kind of output you got a goodern'


its mainly flipping the washers 'big hole to the right , big hole to the left all the way through the stack... they are not all lined up the same way from the start.their flip-flopped...every other washer is oriented in the same manor as the washer immediately under the one in question.
...
its just using 2 bolts to make a +-+-+- type connection to all the plates and to do that you have to flip the plates back and forth is all.
