restoring aluminium frames
« on: January 07, 2008, 09:00 AM »
Hi there,

I'm looking at restoring a few aluminium frames. i wanted to strip them and leave them bare, but I wondered whether this risks them corroding - is this true, and if so, does it really matter?

I've been told that applying clear coat lacquer to aluminium can be difficult, as it tends to go brown and not adhere so well

I remember that the PK Ripper's bare metal finish was described as 'ball burnished' - is that just a marketing phrase, or is that a polishing process?

has anyone tried anodising? anything else I've not thought of?

I'd be grateful for any advice!

Jim

i'm no expert but Aluminium doesn't corrode does it?  also i think the term 'ball bernished' is just the type of polishing proccess, thus finish on the frame.......i've had a nice GT MTB frame in the same finish and it's nice! 
don't know of any problems with clear coat though?  try talking to Superbikedan on here as he is the powder coating god  :daumenhoch:

aluminium will corode but only if it is left outside to bare the elements and then only the surface will oxidise. Bare alu will be just fine for what you want.

yep, correcto, Alu will corode if kept in the wrong environment...., just ask SSB Dan about my old Ripper !!

If it's painted then it should be fine as the paint will protect the alu,...., keep it as is until you decide what ya wanna do with it......and Dan';s the Powder coat man !  :)

"ball burnished" is when you blast the subject with broken up metal bearings, ie, through a sand blaster.

Thanks everyone, I think I'll strip it and leave it bare. I'd liketo add "like my women", but that would be almost totally untrue! ;)

You can get alloy CLEAR anodised. Im not sure if it would be worth doing it to a whole frame, but I get small ally platework clear anodised all the time. It gives it a protective layer but also gives it a very clean, sligtly matt finish.
