Bob,
Not the sinny new tool box, the thing behind the booster, has a handle thing coming out of it. Like a clamp thing. My 'Tuff' thing tool box holds up well in all weather and I can even stand on it to work on my 4" lifted truck.

OH that....
that handle thing is a clamp to hold the Hydroxy test stand onto the table...
there is another in front...
the Stove pipe looking thing is a Piece of stove pipe I bent to form a rain cover for the pressure switch that I have mounted on the board
... the pressure switch is a water pump pressure switch and it works great with the hydroxy generator ...I set it to 15lbs off and 2lbs on but could not get it to kick on any sooner than that ...
I had the power going through the 30 amp pump pressure switch and it automatically regilated the pressure for me ... it works great that way !
I won't use that on the Briggs though I don't want to have a pressure canaster type of run...anyone can do that ...I want it to run from the LPM output alone !
... that will tell us allot !
...

Bob sounds like the moment of truth is near.Hope your experiment proves fruitful,or least taking the first step to running on pure hho.You said at the start of this thread you thought it would take at least 2 LPM to get it started.I'm gonna guess it'll take at least 5 LPM to get the briggs motor to start and sustain an idle.But as they say the proofs in the pudding.
Make us all proud and good luck Bob.

Bob, You might consider a heavy duty electric drill to crank the motor over.

And you may want to attach some kind of flywheel to the crank, I have one that takes a serpentine belt that came off of a compressor. You could always crank from the bottom.

About welders,
I notice that some of you are using welding sets to provide the amps. I also noticed in the Machine Mart catalogue that the welders seem to be giving around 48 volt no-load voltage.
So what is the measured voltage when you are using the welders to drive the cell ?

Manta:
When I use the welder ( havn't in quite a while now)...it puts out over 100vDC ...closer to 150vdc and the voltage stays the same no matter the amp setting... changeing the amp setting just changes the amps ( maybe thats why they call it an AMP selector switch ?)
its indeed rather High voltage for a hydroxy cell but the largest cell I made seams to handle it very well....
unfortionately I have no amp guage that will go to 200 or 300 amps and sense its a 295 amp welder I expect it could reach that amount !
.....

Like manta I'm also wondering about the high voltage,running at 100 volts I would think to have efficiency you'd need to have a cell with almost 50 plates to keep the 2 volt sweet spot for optimum efficiency.Why i think that is because in a doc I read that Bob Boyce started out with 150vdc and 101 plates and then later he found that 81 plates was the magic number for maximum production and that would've been around 1.85 volts(close to around 2 vdc).

Bob that 1 heck of a mean welder sounds like it would draw from the grid in the order of 30 KW
I remember my dad welding at home sometimes it was 28 - 32 volts depending on the amperage but max power was 80 amps I think but I do know that he could not use the full 80 Amps for to long it would keep popping a 10 Amp Fuse ( 230 volts here ) but I think that was if the fridge upstairs was running at the same time
Your welder could pop the substation fuse -
( Bob puts on his armoured clothing to stop the neighbours shooting him ) LOL
Is this welder 3 phase 440V ?

Nope Just a standard 220vac 295 AcDc Arc welder... I bought it about 25 years ago at Costco
in Reno Nevada... it has served me well all these years !
...
when I was running my Big cell on it I started out at 35amps dc and worked my way up
I ran it for some time on 35 amps and it worked very well ... at 55amps the cell was getting purdy warm... and output was an easy 4.5LPM (measured) I went to 75 amps and got the Hose in the bottle and all the lights everywhere went out !...
it tripped the 30amp breaker on the power pole...... I thought well thats silly to have a 30 amp breaker on a welder... what was I thinking??.... OH I remember... thats the only breaker I had ! HAHAHAHAHHAHAHA
...
anyway after resetting the breaker I went and turned off the welder and checked the cables I was useing and they were getting warm #4 size... at 75 amps it looked to almost double the output of the 4.5LPM but I can't be sure of that.
anyway I desided one breaker tripping is enough and went in and re set all the clocks, and listened to my Kid complain because she was on the internet at the time downloading something important to her... OOOPS !
...
anyway... that tought me that there is no substitute to POWER ! ...

I've been looking into making my own wind generator lately. Perhaps instead of attaching an alternator to the mower engine, you could make a small version of the windmill generator... No brushes to create friction, just a little bit of magnetism.

Cowboy ...
You can buy about a dozen bar magnets and mount them on a plywood disk...
have a berring flange bolted to the center and an axel... insted of a hand crank ,put a v belt pully and turn it with a large prop in the wind...
a Coil of wire or a Coil off a lawn mower engine... will get you thousands of volts
and more than plunty to kill yourself with... but Rectified down into useable power should not be that hard...
...I don't remember the name of that generator but it will make a Bright arc about 1 inch long with enough punch to light your EYEBALLS up for a long time !
their deadly, but fun as hell to play with ! HAHAHAHA
...
I've been going to build one for decades now ...but never have got the magnets needed...
something like that on my water wheel could be converted to 110vac with out too much truble ! and power my entire house !
but the speed is critical. for house hold appliances ! so its probly best to drop it down to 12vdc and power a big inverter !
...
this same method can be done so easily by useing an Old wind mill top attaching magnets to the outer rim and have a coil of wire close to the magnets...
you can get AC out of it by alternateing the magnets poles... and then rectify it to DC
or many other things... it is one ot the Most powerfull generators a person can build
and building it is more or less childs play... the electronics arn't but the generator part is super simple....
take something that spins and put magnets on it and put a coil of wire by the magnets and hang on !
..
its a thought... or wild idea anyway ! HAHAHHA

Hg2...
on your guess about how much Hydroxy gas it will take to run that engine....
I agree completely with you on the 5LPM.... 2LPM should make it idle though... thats what I was thinking at the time......
I just wish I had a good charger here and another 12vdc battery to try it with...
because I keep putting off going down to the ranch ...that means allot of work ! HAHAHAHA
...I'll probly go down friday anyway... tomarrow it should rain here...UGH !

Honestly Bob I think it's going to take every bit of 5 LPM just to idle it.

Bob,
You get that brigg's running?
I just ran a 1/4inch sst tube right up to the valve intake to my test engine
no carb. 5HP Briggs. Keep us up to date on your little project there.
