I just had cause to use something my old grandpa had told me years ago, and i'd nearly forgotten.
Ever had one of those bolts, usually a socket head(allen) type that even though you have top quality allen/hex keys, you know is gonna round out?
Put a dab of grinding paste, or valve lapping paste (cause we all have this in our workshops, don't we?) on the end of the allen key and the stuff makes the key grip to the inside of the hex, rather than just displacing the metal and making it round out. it really works, you'd be suprised how buggered a fastener it will turn, even the soft crap ones on chinese/indian shite, then it just snaps the head off, oops.
Not fully rounded out though, then you're screwed.
It works on bolt heads too and philips screw heads.
With experience you develop a feeling for when a fastener is gonna round off rather than loosen, and this works before that happens.
Anybody else got any tips/hints i can pass onto my grandchildren?
Apart from never eat yellow snow.
