i got really depressed looking at the cranks as they where so scuffed and scratched so after average mark said about someone elses xt cranks being polished and looking good i though bugger it im going for it it took 4 hrs for the non-drive and 5 1/2 hrs for the drive side i started by removing the anodizing and bigger scratchs out with a dremal and sanding wheel with 280 grade papers followed by 320 grade then 600 grade then 1200 grade then 2000 grade using disc brake cleaner as the solvent to keep things going as the grit papers where wet+dry after all the surface imperfections where removed and then polished with soft cloth and autosol to achieve the best possable finish i could get and i got this

They look very nice, well done mate. I have a few cranks that I want to polish at some point in the future. The only thing I wonder about is how quickly the highly polished alloy will oxidise and begin to dull. Perhaps it would be possible to give them a clear coat to prevent this, or perhaps it won't happen? ?

Very inspiring though. I actually find myself looking at cranks in poor condition with a view to buying them specifically with a view to polishing them 8) .

There is also a pic on here somewhere of of some XTR 960 (i think) cranks with a really nice powder coat finish which could also be an option.

New to the forum but a lot of experience mirror polishing motor cycle parts.....BELGOM ALU is the best polish I ever found as it leaves a protective,but non visible, waxy finish to the aluminium.....works great...in the rain you can see water beading up on it.....bit of a wipeover afterwards and you're good to go

Looking good ; I'm going to do my LX at some point when I can be arsed . Will probably stick to a 240 grit as any smoother is wasted with ankle rub .

I actually have a set of middleburns I need to find the motivation to polish at my feet right now .

this is the last set I did down to 400grit .

Awesome stuff. How long did the biscuit jar and scales take, or were they a trial run?
