Hi Jeremy, in essence, yours is how I've repaired a few. However, to retain the air space below the stripped hole (below... for welding, the tank is up side down) I insert a thin sheet, or two, of copper, below the damaged thread, and using a TIG torch wilh steel filler rod, fill the damaged hole with a series of circular passes creating a rosette weld.Jdraper wrote:For a longer term/permanent solution I am coming round to the idea of a puddle or plug Mig weld to flood the bolt hole with metal and drill out and tap a new bolt hole. There is minimal space behind the hole, but enough to put a thin plate to hold the weld puddle. If the plate has to stay afterwards, at least there will be a longer thread for the bolt to engage with. I am not a welding guru, but I have seen enough examples of their work to suggest this may be a solution. All I need to do is find someone who I trust and make the tank safe for welding! I think this will be a winter job.
Anyone got any major technical objection to this approach?
