Hi Earl yes This is  a way to get moving and tuning

I published  it to help people get it on bench and testing circuits.
we are working on getting  more precise 3d print ones made  faster
i post on another thread 11 cell  , I can make similar in 6 cell,

but for the one you have  just adjust water levels or gap between cells inner outer tubes

Cut first tube set 1/2" x 3 1/2" and 3/8' x 4" using a stainless steel tube cutter in less than 5 minutes.  I used HomeFex 11-TC-02125 Corrugated Stainless Steel Tubing Cutter, 0.2-Inch-1.25-Inch  around $40.   I got mine at Home Depot, Amazon also has it for that price.  Nice clean cut.  The 3 roller bearing wheels and roller bearing cutter make it very ease to use and 3 rollers make for a nice square cut.

I will need to use a small round file to remove slight ridge on inside of pipe should be easy to do.  I expected that to occur normal when using a pipe  cutter.

 Cool

Here are some pics for others to know

Adding pic for this 3D printed one from a
Home Builder in Indo

Nice he made the  connectors  well and the 3d print is solid

Dan,

Measured the capacitance of 3 1/2' x .5" and 4" x 3/8" tubes in air with the LC-100A meter I have.  Interesting I get different values depending on how I connect meter.   Negative lead on center tube and positive on outer I get ~44pf.  If I switch leads I get 36pf.  This is repeatable.  Note: Value from on-line calculator said it should be 23pf.   

Siding inner tube back and forth keeping both ends either flush or outside of outer tube, no change if value which is what I expected.  To be complete I slid the inner tube so one end was about 1/2" inside outer tube capacitance dropped to around 42pf.  Again this was what I expected just wanted  to verify this is what would happen. 

For these tests I used a plastic bushing at both ends to keep tubes centered.  I also found that touching tubes changed readings and even crossing meter wires had an effect of readings.

Before I started these tests I did check the meter against several capacitors in pf range and meter was within a couple pf of listed value of capacitor.

I was hoping that on-line predicted capacitance value would have been closer to actual value so I could use it to calculate estimated tube length.

reading checking

Earl sorry delay been doing some things, I attached some pictures video from 1 guy who agree to share on this and his steps and leanings he lengthen tubes  , i have asked him to measure similar to you and compare  for now for other here are some basic picture videos of hat Stanley Meyer version 1 looks like with some by pass diodes on cell and the new rapid build 3d cell base using basic 9xb )( 8xa pwm + 9xd power board )  and scr (switch /gate mains)
he made some errors as he learnt , namely wired bifilar wrong left cap off cell and used over spec variac should be follow the wire diagram and use 0 to 220 2 to 4 amp variac max 600 v never over that in version 1, 9xb i left int he videos so people can see the common errors

build errors used too cheap 3d plastic so if temp up it melts he reprinted in high temp rating to cover mistakes, and
he learnt that cell mist have cap water level just above cell tops 1 cm is ok ,  stainless use correct quality or it browns from oils and metals in stainless ,  becareful not to think it is electrolysis as it is not and if you do not have fuse 4 amps in you may fry your bifilar chokes if going over 5 amps in this version1 type 8xa 9xb from Stanley A Meyer

 I did watch videos.

If stainless was machined there will be cutting oil on tubes that will need to be removed.   Puharich in his patent talks about running cells dry for a period as a cleaning cycle as well.

I have not been following the 9xb builds very closely.  But cell builds should be the same.

Have been busy with family events this spring and just getting back to working on cell. 

Earl

The v7 cap piece that I download does not fit tight on the 1/2 pipe.  The center 3/8 pipe is fit is closer.  I used caliper to measure the cap and the pipe and found if I scale the cap down by 96% I got a closer fit on the 1/2" pipe but then center was now too small.  I expected this to happen. 

Looks like I will need to down a program to fix piece as I currently down not have a program to modify stl files.   A quick look at programs looks like I will be able to do the rescale in Tingercad.  Another tools to learn how to use. 

Oh well I bought the 3D printer to be able to do this.

Have not cut other pipes yet as wanted to do capacitance measurements with pipes centered before cutting others.  Initial measurements were done using shims.

Earl

I did get cap redone using Tingercad. It was fairly easy only took a couple of tries to get measurement correct.  Had problem with inside hole for 1/2" pipe being too small. 

I did print cap with a brim so need a little work to remove brim to get it to fit.  I am happy the way it turned out. 

The picture below shows cap on pipes and the tools I used to clean up parts. The large tool is a pipe reamer which can be used to remove the ridge on inside of pipe when you use a pipe cutter.  In this case the two small files worked better as ridge is really small but it is there.

The strips on bottom of pipe are just to keep pipe center and were made from a left-over part of another 3D print.

Next step is to print the base for the pipes and to finish cutting the other 5 pipe sets.

Earl

 Nice thank for pictures it helps everyone learn  Happy 4th Week end every one

Test setup to check capacitance of tubes.

I made a spacer ring that fits over the bottom of tubes to center the 3/8” tube inside the 1/2” tube so I could get a more accurate reading of the capacitance of the cell.
Note:  I made spacer so I could do these tests and to obtain size of holes in base I need use when I print the base.

The meter I am using needs to be re-zeroed before each measure which requires leads to be disconnected.  I also found when I did some initial tests with shims that holding leads affects reading which is why I used rubber band to hold lead to outer tube. I also noticed that the readings were different when I reversed leads but found difference to be much less using the rubber band.  The red lead is positive and black lead is negative.

I did repeat the test several times and similar results.

First picture shows items being used
1/2” tube 3 ½” long
Top cap
Bottom spacer
3/8” tube 4” long
Rubber band to hold meter lead on outer tube

Second picture shows meter reading and test setup with positive lead of meter on inner tube

Third picture shows meter reading and test setup with negative lead of meter on inner tube

Final note while meter never completely settles down with this setup difference in readings are much smaller in range of a few tenths of pf.

Next step is cut more tube sets and repeat these tests.

Earl

  tube cell 1 Capacitance Measurement =  Uf 8-15 volt
  tube cell 2 Capacitance Measurement =  Uf  8-15 volt
  tube cell 3 Capacitance Measurement =  Uf84 volt
  tube cell 4 Capacitance Measurement =  Uf85 volt
  tube cell 5 Capacitance Measurement =  Uf84 volt
   tube cell 6 Capacitance Measurement =  Uf84 volt

I am checking micro farad

videos as he learns and adjusts cell and clean up the steel

note

blocking diode is different from by pass diodes

Remember to check scr and gate time is 3 tau and you have a on / off of gating mains power ac to dc in the scr.

considered Version 1 or part of versions 1 entry level

Dan,

I now have 6 cells made and did measurements on all 6.  The cheap meter I am using also give the frequency being used during test if you press a button, so I included that information in reading below.

Test of 6 sets of tubes outer 1/2” x 3 ½” inner 3/8” x 4” using capacitance meter above
      Outer Pos Lead            Out Neg Lead
        Cap in pF          Freq in Hz              Cap in pF          Freq in HZ
1.   31.75 - 31.80   667140         29.76 – 29.80   667680
2.   31.95 - 32.01   666750         29.83 – 29.93   667444
3.   31.32 - 31.47   667160         29.71 – 29.74   667840
4.   31.95 - 32.03   667108         30.20 – 30.33   667550
5.   31.51 – 31.63   667310         30.25 – 30.33   667735
6.   31.96– 32.07   667007         30.43 – 30.57   667512

   This one is with bottom spacer on both ends so inner tube sticks out both ends. I wanted to see if capacitance changed to see if this could be used to tune system.
7.   32.86 – 33.11   667540         31.19 – 31.31   667840


I am glad to see that they all appear to be fairly close in value.

Thanks for the videos nice to see someone else working on it

Earl

 
YEs Looking good our tube length 
our shown unit above
length of tube is 23cm /9.05512 inch for inner & outer tube,
there are 0,5cm / 0.19685 inch  difference in length..

Yes, is good to see others are still interested and have not give up!

 Earl ,

Any pic of you cell with water in ? it may help people compare 
here is video of  base


Dan

Earl Re Cap Measurements we are measuring with water in  not dry

Also I think i forgot to mention we have limited our input to 40 vdc  and un 4 amps
so all pics video are at 40 vdc  this is so we fine tune before ramping it
we know it makes plenty of gas we tune the low end

Dan,

I am still building the cell.  I had stayed away as I expected it to be harder that to do than I thought.  I did dry measurement as I do not have a way to do that in water yet.  Currently printing tube holder base.   Still need to order a 4" tube to hold them not sure of correct size to fit holder.

I am looking at table of cap value from Stan estate and it has measurements for dry cell they were all 21-22pF for a single cell.  Then jumped to 679nF for single cell with distilled water.  There is also a value for tap water but not sure if that is city water or from a well as it makes a difference.

Nice thing about using 10 cells their total capacitance value is just a tenth of the value of a single cell.  It just the way the math works out.

Earl

This slide is from stan we added the missing items  several people measured the  ultra doubled distilled pure water  as fuel value and we got this .

The Charts for Ph  one can note there are in
existence but not yet remade or found 
Ph chart which go to 300 ph etc  ( if any one would like to draft  such a chart or pist succh a ph 13ph to 500 ph Chart )
please do

longer tube more gas

also longer tube in need designs or latter delrin design more gas also
short tube means high volts to get same result

the refresh of things still happens and is shared daily to people rind the answers.

Dan,

I cut a 9" pair and measured the cap same way I did above

78.45 - 78.87pF for Pos on 1/2 and 72.61 - 72.68pF for pos on 3/8"

I also printed the tube holder, but holes are too loose for my pipe.  Same issue I had with cap.  If the person that did the video had same problem some of the cell could be shorted out.  I did play around with test print single cell in picture below and got a nice tight print.  I may be able to get a tight print of holder by just changing scale of STL file before print.  Did not work for cap as it made center post too small, but it may work for base as both holes are too loose about the same amount.

Picture also shows the 9" pipe and hole guide.

What size clear pipe are people using?  It looks like 4" shop dust pile in the photos above should be OK for initial test, but I would recommend it for cell under pressure.  I can get schedule 40 tubes, but hole drilling guide would not fit as OD is 4-1/2"

I did purchase some stainless 1/4-20 x 1-1/2" stainless set screws with hex head to see if they will work.  I also purchase stainless lock nuts.  I saw in forum where someone else did this and just used hex head to hold springs.  I will report how well this works.
