gas tank out of trash
I've always wanted one of those under seat gas tanks.
I made this out of 2 propane tanks that go into a little heater.
I welded the two rounded sides together, and cut the ends then filled in the gaps with putty, then painted it with that hammered paint (laying around).
Next I'll seal it with Kreem or Caswell, and put the filler and petcock in it.
