Kevin's 5 tube design
Kevin:
I just got a couple tools to do some testing on my cell. The cell is 90% done. I'm having issues with tapping through the 304 SS. Broke my third bit today. Gonna ask my machinist friend where to get better bits. I should be able to finish the cell after work over the next couple days. I have been filming the process and I'll upload the videos here once I'm done for the other DIYers on this site. My 3 bubblers are done. Just have to find my bronze wool. I also purchased a mini torch tip. This is all the easy stuff, but in order to get up to speed with you guys I still have to build my circuit boards, get an alternator and 1-2 HP electric motor. The site has been hopping the last couple days Hydro. Congrats man.
NEW TOOLS:
---Variac 130V 10 amps with a max load of 20A model SC-10T
---WAVETEK
50 MHz Pulse Generator
model 801
s/n P6950874
5Hz to 50MHz frequency range
100/120-220/240, 48-66 Hz, 60 VA max
* operating modes include: Continuous, Triggered, Gated, Burst & Ext Width
* provides 20 V p-p output (maximum)
* variable rise and fall times (7 ns to 250 ms) and independent width and rate controls
* all outputs can be used simultaneously (four fixed and one variable)

POST BY KEITHTURTLE:
"On drilling 304:
I get by with the cheap titaninum-nitride coated bits from Harbour Freight, and use a drill press at 330 rpm and plenty of heavy grade cutting oil. Take the time needed to make the cut, start by grinding a flat so ye ain't rollin' offa the curve.
Start small, 1/8" then step out as needed.
Plan on 5 cuts per bit then throw 'em away.
This business ain't fer folks skeerd of spendin' the turtlebucks.

Thanks turtle,
I have yet to break a drill bit. I have broken 4 tapping (used to create threads inside the drilled hole) bits though. I was able to salvage a couple of them by grinding them down. I used Senco pnuematic gun oil since LOWES didn't stock any drill bit oil. I ran the drill press I have at 550 rpm's which is the slowest it will go and it worked fine. When tapping you have to use the hand tool specifically made for the tapping bits. I also tried a variable speed cordless dewalt drill with a clutch, but the hand threading worked the best.
So I finished my cell finally a couple days ago filming the process as I went. The final dementions are 4.5"x16" with the tubes being 5 sets @ 12" tall. 321 SS outside 304 inside. I'm waiting for a couple components before I start doing tests on my cell.
Hydro:
I would like to contribute to this group and focus my efforts on problems that will further the research going on here, but I still have to build my circuits etc etc etc. So, until I get totally up to speed with you and others here I will be trying to determine the BTU value of the hydroxy gas compared to normal hydrogen oxygen mix.
Oddball:
Welcome to the forum! You have some excellent ideas and I look forward to seeing what this group can do with the additional knowledge.
I'll be posting some videos soon.

Kevin:
I will be uploading some videos for the DIY'ers on this site so people can see how I made my 5 tube cell.

Does anyone know a good place to get SS wire? I'll be going to a marine supply store soon and hopfully they will have it.

keithturtle:
Good approach, Kevin. I'd use washers betwixt the bolt haid and wire to more evenly smash yer wire and prevent the twisting of the haid separating strands
