this is my first real attempt at a tank made completly from scratch.
this is my first actual metalshaping project that involed shrinking and such, so feel free to comment, i really need to know how to improve my skills. its an ok beginning project, but as you can see, i still have a ways to go.

Your tank seems to be progressing. You have a few places to address, but keep up the good work.
I couldn't help but notice the frame.......it will break as it is now. If I can help, let me know.......john

the links dont work.....
yeah, the frame is just tacked together, i still have to gusset it and stuff
john, how can i make the edges look a little better? i welded it all with a mig, so i had some shrinkage.
i will get some better pics up, so you can see different angles.

Parker, you will need to grind the welds down flush with the panel inside and out, ifyou havem't put the bottom on yet. You will also have to take a body hammer and a dolly that fits the radius of the tank at the spot you are working and hammer "on dolly" to stretch the areas that have shrunk. You do not want to stretch outside of the HAZ (heat affected zone), as you will only create new problems. The HAZ is mostly the part of the steel that changed colors around the weld. In the future you may want to use this process as you are tacking it up, it is easier to get a good job if you keep it straight as you go.........john

The tank looks pretty good so far. If you have shrinking take your hammer and dolley and start hammering the welds.
Like John said, as of now that frame would break pretty easily. We dont want anybody getting hurt now.

thanks for the tips, everyone
John, i need to grind the welds on the indside of the panel as well? i just put the tunnel in yesterday...how would i get a grinder inside to grind the welds? die grinder?

To planish your welds, you really need to get behind them. I would take the bottom off if it is just tacked, straighten the top then proceed with the bottom. You are skipping around and only doing very short welds aern't you?..............john

i have finished welding the main part of the tank, and the welds are ground. sorry, those are kinda old pics.
