22 gallons. My other tank held 19 gallons. It sure goes down fast at W.O.T with a Johnson 150GT :shock:.

Nope no foot pedal.:mrgreen: Was standing up the whole time. Just walk the cup and feed the filler wire. When it was about to blow through, I would stop the torch. Then I would restart. Aluminum sure cools down quick compared to steel.

Here is a pic of the tank position in the boat.

I just got a job in today for a pretty large tank. Its goin to be 1/8 5052 aluminum with 4 baffels. I dont have any pictures yet because i only sheared the belly of the tank and tommorrow i will finish shearing it and bending it and start welding. I will post some pictures tommorrow i hope. For now i have some old pictures of past tanks. Sorry if this didnt work i am not really to proficient at this.

Very good excelent looking welds. Was this done with TIG or MIG? looks like MIG to me

junes
08-12-2009, 07:55 PM
nope it was all done with TIG. The bottom two pictures are blurry they were taken on my phone. Also ass seen by all the fittings in them they were just pressure tested so there is alot of soapy water and leak finder still on the tank seams.

I don't see the difference much between my welds and yours. BTW....The tank is holding up very well. If you know what kind of boat I have, you would understand that the tank has already been through the rigors of testing.:wink:

Principal Design Features
AL 3003 is an alloy with very good corrosion resistance and moderate strength. It is not heat treatable and develops strengthening from cold working only.
Applications
Commonly used in chemical equipment, ductwork, and in general sheet metal work. 3003 is also used in the manufacture of cooking utensils, pressure vessels, builder's hardware, eyelet stock, ice cube trays, garage doors, awning slats, refrigerator panels, gas lines, gasoline tanks, heat exchangers, drawn and spun parts, and storage tanks.

ok here we go,

First jsut because it is used for gas tanks doesnt mean it is a marine grade. Second the difference between my welds and your welds are i have pennetration you really dont. Now that the flood gates are open let go over your design. First your baffles are they welded all the way around meaning the top too? No. Are there enough holes to allow gas flow? No. Do they lookk like they are welded enough? No. Do you know how much gas weighs per gallon? Now the really big problem do you have holes in the top of the baffels? Nope. Now how do you expect to get all the air out of the tank when filling? Just wat i see this comming from someone who makes fuel tanks for a living.

Which mill is that in your shop? Good job on the tank - everyone has to start somewhere!!

junes

yes everyone has to start somewhere and a gas tank is not a place to start at all. Sorry but it true.

henrym
08-28-2009, 09:23 PM
Junes definitely sounds harsh. but! this is a gas tank for a boat! not something I would undertake without complete understanding AND adequate skill & experience to match.

stuck in the water with a burning heap of metal is a consequence of failure! dead is another


still, we have not seen the tank or construction first hand. it could be fine. but the scare is that any (unseen?) weak link may fail unexpectedly over time. take no chances on a fuel container.

no harm meant, take care! :)

Gentlemen,
Pride sometimes is a hard pill to swallow. Speaking for myself I can tell you first hand what gasoline can do to. And it will do it in a Hurry! I am not going to speak for either party's behalf. But as for me, which happened not too long ago, I was removing fuel from a gasoline tank, out of a truck, which had been filled up with Diesel fuel. I know that Diesel doesn't have the fuel vapors or the volatility as gasoline. I in my mind was sure that there was not enough gasoline in the tank to matter (Pride). Still keeping in mind I know any fuel is dangerous. We at our shop had devised an electric fuel pump which we have used for a few years just for this issue. No problems and worked great! For some reason this day I was using it something was not working... I was standing over the tank and reached in to remove it to investigate the problem. Not removing the power from the pump (Pride) was confident that nothing would happen. Even commenting to another about what if sparked while I was removing it (Pride). And guess what, it did, and it happened so fast I didn't even hear the woof sound it made said by others. All I heard was air rushing past my head as though I stuck my head out a car window. Stupidity is not something I like to admit, but in this case I had all the warning signs and ignored them (Pride). This one I will concede my pride for it is greater than I. Now we do not use that system, it has been discarded. We have since aqquired a fuel caddy with hand pump and I use it greatfully. On that note Huck_this, It is good to be proud of an accomplishment. It is a great feeling. And sometimes it is hard to take constructive criticism. Even myself am guilty of. Look at it as this. It is also possible that junes is looking out for your safety as well as criticising. I myself can see your points and I see junes points as well. But from me and others on this site want to keep you here and not in the burn center. From what I have read from junes, he is blunt... no doubt about it. It is nothing new and from what I have read he has good info and valid points. But if he does this for a living it, should be worth listening to. And maybe junes could be could try to bring up valid points first before blatently saying IT WON'T WORK.
On this site if we work together we will get farther. I don't know everything nor will I attempt to admit I do. I keep an open mind and always try to keep learning. I have a saying that I say all the time... "There is always more than one way to skin a cat". So lets listen up... If you have something to offer, give it up.

I hope this didn't offend but I am speaking from what I believe.

Steve

Keep posted I will load my burn pics later....

junes
08-30-2009, 09:16 PM
If you look back a few posts I listed about 5 os so things that he did wrong and that could be dangerous. Yes I put it bluntly but this is how I was taught and whenit comes to your life or other peoples lives I am not going to beat around the bush I am going to tell it like it is. Sorry if I have offeneded anyone. If the reasons y it won't work right didn't post I will by all means post it again.

Some more ideas on fuel tanks! I'm not a tank builder so have no comments on this thread, just learning on it...but noticed a real good thread on weldingweb.com for those interested in more info on fuel tanks. It's under "aluminum fuel tank for small boat" and the guys there show lots of photos of tanks under construction and have some great knowledge including aluminum types to use, gauge and baffle construction. Worth a look see for anyone going down that path, some pretty neat stuff there.

Hi Everyone,

I was just made aware of this thread spiraling out of control to the point where it seems like another childish welding forum. Art said it right - this is a place to learn and share your knowledge and not a forum where we allow degrading and belittling.

If this mess continues, we will lock the thread! No one here is the king of welding, and no one here has the right to put another down.

I have been watching this thread for a while now but have avoided contributing. It seems like the main point people are trying to make is if you life and safety depend on something keep an eye on it. It doesn't matter who welded it you or a pro or if it isn't welded at all. Gas is no joke as steve pointed out. Any fuel system left un maintained has the potential for leaks. True if you tank is new and professionally made it is less likely to have problems than a old home made one but it is still worth checking every so often. I had a friend with a old POS car and when I was jump starting it I noticed that the fuel line leading to the injectors was leaking gas on top of the engine and spark plugs. Thankfully nothing caught fire but the potential was there for sure. As far as I know it was all factory fuel stuff but nobody had looked at it in 10 years or more. How often should you check stuff?? I have no idea but more often than never.

I know most people here on the forum are older and more experienced than me so I don't mean to sound preachy and I am sure everyone already knows it is good to be safe. But I also think it's good to have a reminder every now and then.

My ass is in that boat and so are my girlfriend, her kids and the dog. I would not jeopardize my life or anyone elses. I checked that tank. Put water in it and pressurized it for 2 days. I am watching it like a Hawk. Check before and after any outing I do with the boat.

If I wouldn't have felt comfortable about it, I would have scraped the project.

I was just tryin to explain how to corecrly build a fuel tank. If you put water in the tank and presurize it it's no different then not putting water in it. Also usually we dons test with water due to differences in viscositys. Do you understand what I was saying about how the baffels were not designed right? From what I can see at least.

Nice tank, huck, and I'll look out for you next season. My boat is in Pointe-Calumet, between Oka and Deux-Montagnes. Of course it's not as fast as yours (hull speed is 7.2 knots, 4-stroke Honda 7.5 hp), and it carries a lot more sail.

I may copy parts of your design next year, but in stainless. For a fresh water tank.
