light scratch on crank....doh!
Anybody any quick and simple ideas?
Just sticking some new big end shells in my Xe 16v Vauxhall engine for racing this year and just decided to be clever and mic up the
crank...............succeeded in slightly scratching one journal with the mic now (ruddy carbide tipped mics!!!:mad
Any ideas on removing the scratch without pulling the bottom end to bits first? I guessed some 1500 grit wet and dry to polish it out as it is only a
very fine scratch.
Nothing's ever simple is it!!

Did the Ye Olde engineers use a leather strap and metal polish?
or did I imagine it?...........................

crank
try an oil stone
one that you sharpen wood chisels on
with a little light oil and use a rocking motion so as not to put a flat spot on
when you start this journey
you think it will be done in " no " time but then " no " turns into a " bloody " long time

When i worked for a company that ground cranks we used scotch bright or very fine wet and dry for the bad scratches. Dont put an oilstone anywhere
near it :0

cheers for that Paulf, you've confirmed thhe two things I was thinking about using! I have to be careful as I don't want to take the crank
out so need to do it in situ, but the scratch is very light so should be ok. I'll go for 1200grit wet and dry and shine it up with fine
scotchbrite after.
Cheers,
Nat.

wet and dry cut into strips and Brasso --- don't touch it with anything solid like an oil stone.
