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?...........................

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 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.

seeing as you've been giving me grief elsewhere..........


you plonker!

yep, I know.......I am!

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