Stainless tank mod.....

admin

Did some mounts on a Hot -Rod gas tank today.......The customer tacked the mounts himself and did a terrible tack job making it tough to finish near the tank flange....But he was happy and I got paid...  Miller Dynasty 350Twenty Six HammersThree Crow BarsBig Rock
Reply:Nice job. But, and don't take this the wrong way, I can see the welds pulling a hole in the tank once it starts flexing. Should have used a bigger plate under the mount and then weld the mount to that, spreads the stresses out a bit. As well, the corners should be rounded.....Mike

Reply:The customer brought it to him tacked together.  Any failure will be the customers problem. As the hired welder, the responsibility for the design and design failure is on the customer when it comes to you already tacked.Nice work, as usual Bill.Two turn tables and a microphone.
Reply:those corners look rounded to me looking Good bc
Reply:How long did it take to purge that tank? Also, with argon being heavier than air, what did you do when it got half full and equal to the height of where the argon supply is? Wouldn't it try to just push argon out where it is being introduced leaving air on the top side still?And also, that guy popping a wheelie on the motorcycle should REALLY be wearing a helmet...
Reply:Good Job looks good.
Reply:That is awesome, that's what i'm talking about and I love welding stainles steel. That what I want to do for a living once I graduates in may 2011.it's trust and character I need around me. You know, who you choose to be around you lets you know who you are. One car in exchange for knowing what a man's made of? That's a price I can live with. - Hans

Reply:Originally Posted by B_CI turned the purge way up for about three minutes then turned it down to 10CFH  had a bleed hole at top and flipped the tank while welding.....don't think there was a problem especially with the weld looking like it does.....
Reply:Hello B_C, nice looking job of welding. I enjoy the heck out of welding on SS parts/weldments with the GTAW process. Definitely not a well thought-out/engineered set of mounts for many reasons, at the same time, not your duty to make changes. Likely the individual who brought this to you wouldn't have listened anyway. I often find that the many different items that are brought to me for repair/fabrication could use a lot of tweaking or re-thinking, sometimes I am fortunate enough that they haven't already made up their minds and I am able to explain the choices that they actually have and why one might be a bit better than another. Any tanks that contain fluids and are subjected to motion in any sort of vehicle can have problems with being susceptible to cracking. If they don't have properly placed or applied baffles there can be a lot of flex that can cause stresses and cracking to result. Strapping is really the best choice for mounting a fuel tank, takes the flex out of the mounts and prevents problems with breakage and leaking. Any time you only have a weld on one side of a joint or only partial joint penetration, if there is flexing in the application, you can experience a crack-prone design. I'm not bringing this up to criticize your job on this tank, but more so, to let others who might not have your experience, come to understand just a bit more about this sort of thing. Best regards, Allanaevald
Reply:Originally Posted by DiabolicZOh no, I wasn't saying there was a problem. I just have zero experience with back purging so far, so I ask questions.

Reply:Hello B_C, don't have any pics, but will try to get together a sketch or something. I am not saying that that sort of a mount won't work, yet in a 32-35 Ford it's unlikely to see the sort of action that other vehicles will. There are also many ways to skin a cat, some work better than others. When you consider most vehicles that are on the road and produced in Detroit or other automanufacturing areas you will likely find that their tanks are also strapped in and mounted in rubber or with some other compressible material. That was the basis for my comments. Also, the area in which I live is heavy into off-road applications: Rock, mud, snow, and sand, all of these mediums will tax the limits of any vehicle. I'm short on time right and will get back to this. Best regards, Allanaevald
