What is ball burnished?
« on: December 14, 2012, 10:12 PM »
Hi all, after a bit of info. I am looking to polish an alloy frame and then lacquer it, to keep its shine. I have done this in the past and had a real mirror shine and then i got it clear powder coated.......it lost all its shine. The frame currently has the mirror finish but is now over ten years old and I wish to restore it but just dont know what the correct process is. It really looks like chrome but just dont know how its done? I have heard of ball burnishing or am I barking up the wrong tree? Cheers all  ???

Ball burnished is a different thing altogether , it also goes duller in time .

If you want it to stay like chrome , without sounding funny , have you thought of getting it Chromed or chrome powder coated  :daumenhoch:

If you want a mirror finish to your frame then get a polishing kit, either for an electric drill or bench grinder/polisher this will give you what you want.

Ball burnished is when a piece is placed in a vat of moving ball bearings, which hit the frame repeatedly and this is action is used to polish the piece.

The problem with getting chrome powdercoat is that you need a clear over the top of the powder which then makes it a very shiney silver.

I think  he wanted the bike to be like chrome and like a mirror finish , Sean  ???

Like chrome and shiny :-\

He was complaining he'd got it shiny ,,,,but then went duller when it was clear laquered ,,rather than maintaining a permanent shine  :-\

Thanks all for your replies. Well I never knew you could get alloy chromed? I thought it was only steel that you can chrome, possibly thats what the finish is now then? I didnt know you could get chrome powder either? Well I have a few options now, getting it proper chromed could be the way to go....excited now. Cheers all  :daumenhoch:

Yea, its a mountain bike 24" frame and its very thin alloy as it pings when you flick it. I suppose they are just strong in all the right  places  :-\

Sorry Christian wasn't actually having a go there mate, I wrote it on my way to do something else and didn't word it nicely.

I actually didn't know that you need a clear powder to go over the top of chrome powder, it was something SBD told me recently.

Who said anything about O/S or mid school  :)

, it's a mountain bike that is already polished and he wants to maintain it's shine by putting a clear coat on or alternative permanent finish ,

 so then he doesn't have to keep polishing it  :)

That's the way I read it ,, I could be wrong  :)

There is now a painting process that will make it look exactly like chrome. That or get it wrapped. Thats if anyone is good enough to do it to a bike
