Alloy polishing

(1/2) > >>

MrDavo:
While I like the vapour blasted finish on my CB750 engine, it isn't appropriate for either the fork lowers or the engine covers, but that's how I got it. The cam cover can stay how it is for now, as I can't be arsed to take the engine out just to polish it properly.

Although it is something I could possibly have a go at myself in the winter, anyone know of a decent polisher in the North West, and have an idea of the cost?

Anyone had a go themselves? I reckon the first 'cut' will have to be quite aggressive to remove the matt finish I have at the moment. Also as I want to laquer the result, both so it looks original, and so the 'monkey metal' alloy doesn't go nasty too quickly. How do you finish the alloy to key the laquer, and what laquer did you use?

Any tips or experience will be gratefully received.

There is some stuff called Alodine used to prep alloy but expensive and nasty stuff. Some people have suggested powder clear coating but not tried it,
I am sure with various grades of wet and dry and Solvol you could polish, or geta sizal mop and polishing 'soaps kit. Problem is getting the correct original satinised finish on fork legs. Going to try all this myself over the next month so I will let you know.

Hi folks,
Getting that finish back on the forks is usually only an hour of a job.  Things like cam covers with awkward corners are a bit more of a challenge.
Some time back I put a little 'how to' piece on my web site about this very thing. I'm away in Germany at the moment, so I don't have the link to hand but if you go to my site (the globe near the avatar)and have a look around the GB 400 TT section, I think it's there.
Hope this helps,
Ian

Orcade-Ian:
Ah! Just found the piece in GB 400TT part 2,

There is a bit on my web log of how I polished the forks on my cafe project, near the bottom of this page, after I rebuilt them I buffed with a lambswool polishing mop as can be seen on this page 8th picture down. I didn't lacquer them though, I just give them a light buff by hand from time to time with Autosol then polish with AutoGlym Super Resin for protection.
