Metal finishing

[jfjfjf2]

Does anyone know of a company in SW that does glass or plastic bead blasting? It's for aluminium castings (Rocker covers etc).

Thanks,
Julian

Soda blasting is the way forward it wont damage the alloy underneath
frosts do a kit cheaper than you will pay anyone to do it

I might have already told you about this?

I done the one on my Merc Cosworth using my equiptment at work. It's not walnut shells, or glass beads, but a really fine aluminium oxide we use for glass frosting.
It will leave a slightly rough finish, which can either be brought back up to a shine with a polishing wheel, ready to accept paint, or go to the platers for nickle/chrome/annodising or copper plating.

If I can be of any help, pm me and I'll endeavour to do my best.

Thanks for the reply Dave, I don't remember that conversation but I am going senile. If I can't get it done for less than the £400 it would cost for the soda blaster + media + delivery + suitable compressor, I'll not bother. Vidals reply looks promising, I want to reduce the roughness of the original casting prior to polishing, I shall pm him.

Cheers,
Julian
