Having just emptied a propane tank while making bacon, I couldn’t find any of the wrench adapters I made to remove the QD adapter from the tank’s POL fitting. With memory of the broken garden valve wrench still fresh, I tweaked the solid model to include a trio of 1 mm music wire reinforcements:
Holes that small require clearing with a 1 mm drill, after which ramming the wires in place poses no problem:
Except for the one that got away:
The music wire came from a coil and each snippet required gentle straightening; perhaps that one wasn’t sufficiently bar-straight.
Anyhow, I printed two tools for that very reason:
They’re now where I can’t miss ’em the next time I need them, although that’s not where the previous ones reside.
