Coaxial Power Plug Tip: Extraction Thereof

Another coaxial power plug lost its tip inside a lithium ion battery pack used with the APRS + Voice circuitry on our bikes, as I could barely see at the bottom of the socket:

LiIon Pack - output socket

Rather than cutting the pack apart, I buttered up the end of an intact plug with some ABS solvent glue (a hellish homebrew mixture of acetone and MEK), rammed it into the socket, and held it in place for a minute:

LiIon Pack - undamaged plug insertion

The tip emerged on the first try:

LiIon Pack - rescued plug tip joined

LiIon Pack – rescued plug tip joined

Even better, it cracked off the plug without too much effort:

LiIon Pack - rescued plug tip separated

LiIon Pack – rescued plug tip separated

More solvent glue and a few hours of clamping worked fine:

LiIon Pack - clamped plug tip

That cable is now back in service.
