Title: Aluminum swingarm resto tricks wanted
Post by: PEZBerq on September 25, 2011, 10:16:48 am

Am starting on a resto of a new fangled single shock, water cooled disc braked four stroke Husky 510. Never having dabbled in the art of restoring alloy swing arms before I am after advice on how to get that OEM brushed aluminum surface appearance  ??? ???. Also were swing arms finished  in raw aluminum and clear coated or did they have an anodized finish. Any guidance appreciated before I stuff something up  ;D ;D

in the latest vmx mag article of Anthony Gunter's RM400, he mentions a mob in Brissy that brush-finished his swingarm and then clear powder coated it. I'm don't know if that was the original finish on your Husky though.

If I remember correctly, that era husky (86-88 I believe) had a painted alloy swingarm, sort of a grey/ silver.

Being a cheapskate, I would get a scotchbrite wheel on the benchgrinder and brush finish it and then spray it with a can of urethane mag wheel clear.

This one's definately painted, you can see where the paint has been removed when a repair was done to the chain adjuster nut/bolt set up. ???

Alot of arms are anodised silver and it looks like paint when a bit comes off.....its alot of work to paint a swingarm and make it look good (alloy ones are alot bigger than steel ones and would probably require a special primer) and it would take away that "special" look you get with a painted one....just adding a confusing thought. :)

I find a lot of alloy mufflers to be painted
Modern Husky & KTM's most definitely

How can that be cost cutting, I'd imagine it's dearer to paint then to plate the spokes?
