Re: Old dog learns new trick...Welding!
The gas tank sealer kit arrived so I got to work on my project. The tank was already showing some rust from where the soldering flux was. I cleaned it up with the side grinder fitted up with a flap disc.
Instructions in the kit suggested using duct tape along welds to temporarily seal it up while using the chemicals. I use the actual metal kind of duct tape (known as Indian chrome on the Rez where it is used to patch holes on reservation cruisers. Works good and shiny, too). I like to use this stiuff to line the inside of bicycle rims to protect the inner tube from spoke nipple abrasion. For that I cut it half width, which is also what I did for this application.
Now the weld areas are covered and we're ready to go...
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
