    i had success at first with this joint. i ground it back to help the appearance. this is .060 ish size material. they call it 16 gauge. I am using and Everlast mig welder with .035 wire. more on this...

      here is the inside of that joint. looks okay to me for penetration... not the prettiest.

          so as i was welding up the tank, i started to get into trouble. i was moving around... but obviously not enough. it started blowing holes through. now here my thoughts. i don't need or want .035 wire for this. i have order .023 wire and tips. they're on the way. i have cut new panels and will attempt a second tank. this one will be kept for demonstration... second the welder isnt very user friendly. it has no chart and no real settings. just 2 dials with infinite ranges. so tuning it in is a challenge. i should have gotten a little better machine... but here i am.

            also, i understand TIG welding is probably the way to go with this thin sheet metal. i do have a low budget TIG welder... but again... no argon bottle as of yet. also its a scratch start... or lift arc... so... again not the easiest nicest machine to use.. but maybe a bottle of argon is in the near future.

              Practice makes perfect! I can't wait to get a nice welder. You decide on a battery yet? that Shorai I'm running is holding so far but i do have it basically floating in mid air. i guess they DO NOT like vibrations from a harley.

                No choice or purchase has been made yet. I'm leaning towards antigravity... but that could all change... which it usually does.

              why not just fill weld the holes rather than start a whole new tank?

                well... i may very well do that and keep working on the first tank... but for me repetition helps me learn... and i am picky... if i don't like the way something looks or functions or turns out I'm gonna redo the work.

              alright... so i finally got all my shit together. got the .023 wire and tips... of course the tips i ordered were for a different style gun, but a quick run to the welding outfir here in town this am and i was welding away in no time.

                  so, i think im gonna grind a shit ton of bad welds off the old tank and give it a try rewelding it. i still have most of the [parts to redo a second tank.. and that may just happen anyway.

                    okay... progress. i switched to .o23 wire and played with the setting on the machine and got decent results. I started a new tank and used some different methods.

                    i learned that patience and a correct set up on the welder is really crucial. patience more than anything. i will be upgrading the mig welder to something more adjustable in the future. the .o23 wire really helped too.
