Heres a pic of it. I will test it for leaks with the manometer we have at work.
Cheers, Fletch.
Oh, They'er solid ali rivets...

I know what your thinking and a riveted fuel cell wont leak,trust me. They are fabbed this way in many aircraft.

very nice tank.

Very impressive 
Is doing this within the capabilities of the average home builder? I'd love to have an ali tank.
Would there be any point to posting a little tutorial?
Probably a blue-ribbon dumb-ass question: You said that it's a fuel cell, so what are you going to do for a liner, baffles, filler, etc.?
Pete
Nice 
It looks great.
I'm sorry I said fuel cell out of habit. It was shot together "wet" with a mil-spec fuel cell sealant known affectionately to aircraft
mechanics as Proseal (prostink). I just fabbed the parts as if I were going to weld it and shot it together (riveting is more in my comfort zone).
This turns out to be the same method of construction as a "wet wing" on aircraft. Steel would work just as well and would be easier to form
the end pieces and baffles.Use monel rivets instead.Pete, the baffles are formed on the same form block as the end pieces.I just cut the corners out
of them to let fuel pass.I got the design off Mike Polans web site.
That an EC-135 helicopter in the background made by Eurocopter....
On to the floor!......
Cheers Fletch.

fuel cells made in this way do leak on aircraft, more due to flex in the wings, i dont think your cell will leak as its in a car and so much
smaller.
was there a reason for using proseal, why not us a regular a/c sealant like 1422 b2.
thats what we us on the c130's i work on.
(although i dont surpose your paying for it!!!)

I used AMS-S-8802A B2 because it was free(out of legal date). 1422 b2 is a hightemp fuel sealant used in fire-wall and engine deck areas is'nt
it? We use very little of it anyway so not enough of the stuff around to go legal date on us.
If I remember its brown and possibly the only thing that smells worse than proseal..
Cessnas,Beeches ect.. G/A Private planes that use gasoline typically dont leak which what I was refering to. But your right,C130's ,141's,
C5's all leak simply out of spite I think 
Fletch
im not familiar with your ams number, but we use 1422 as a general sealant, the only proseal we have used is proseal 800 which we use for high temp
sealing on electrical pressure bungs on engine firewalls. this is a very nasty type of sealant, 1422 fairly ok.
anyway this is getting really sad, i feel like im taking about work all the time.
good luck with you fuel cell.
elite wiring you really should get out more!!!!!! (by the way its ps700 on the fire walls)
To bring this topic back to a more normal level (basic toilet level) can we put a warning in about using brown smelly stuff to seal tanks.
Hmmm PRC 1422.... fantastic stuff - you could use it to stick bridges together.......
Oh yes and the heavy fumes are great when your working on your back under a fuselage applying it as a sealant.........
You lads sound like you could start assembling robin hood / lolocosts new rivited car (Bolteon) it would then qualify for the low flying title.
any one got any ABE 320 epoxy.....stick like s***T to an army blanket...
I was wondering if one coule pop rivet a tank and seal the rivets with some epoxy on the outside then seal the inside with a regular automotive tank
sealer? looking for ways to fab a tank with ease.
(looking into a monocoupe for the next FSAE car)

Some "wet wings" are pop riveted(in places) with Cherry Max rivets and sealed from inside, but check on Cherry Max prices and you'll know why we are building 7's and not 172's.My tank was shot together w/ms20470ad4-3 solid rivets (about 200 or .50 cents worth) and $16.00 worth of aluminum.
I'm going to build one for a guy building a bec as soon as he settles on some dimensions. If you get someone to help you shoot'em, you should have no trouble.
good luck! Fletch
