- Making tat look good
Manky old set of Deore square taper cranks….
(like these but found in a bin and scratched to buggery and filthy)
….bit of work with a drill and wire attachment to take off anodizing….
….then polish up with some fine grade sandpaper, metal polish, and lots of elbow grease….
(I decided to leave the spider with the satiny/unpolished finish as a contrast)
….ok not quite up to Jeff Jones standard – but they look pretty nice 8)Posted 8 years agoajantomMember
I know they'll get a bit dull, but I've polished em with a bit of T-Cut, and will only take a quick re-polish every so often.

Oxidisation on Steel and Aluminium works quite differently too. Rust on steel and iron causes structural degradation over time, but when aluminium oxidises a very thin layer forms (we're talking microns) and this layer prevents further corrosion.

Good job well done, I like 'em. I did some LX HT2s like that and they've been fine. Looks waaaaay better than scratched and worn paint. The finish stands up just fine to usage. I found that Brillo pads are great for the final polish too, the ones with the soap in them! 🙂
If they had 'Middleburn' written on them , the nay-sayers would be fawning over them…. 😉Posted 8 years agoracing_ralphMember

Someone should tell the aircraft industry then, they spend a fortune on preventing it oxidising.
its a pair of cranks not a **** airplane!Posted 8 years agoCountZeroMember
Aircraft structures use thin section materials, where any corrosion could cause serious stress fracture problems, especially as alloys can become work hardened and brittle over time. Not a problem on bike components, but an issue if you're trying to keep seventy tonnes of aircraft 35000 ft in the air.Posted 8 years ago
