Sand blast finish

I have to confess that this would be more of a vanity project than one of urgent necessity! The photos are taken for my reference, as I have found (often to my cost) that weeks later when you come back to bolting things up, the distant memory does not serve well!
I used to work in the casting industry and a fine blast finish is great, it hides a multitude of sins and casting marks, but it is also a magnet for dirt and crud that is impossible to remove (let alone dirty finger prints!).

So I had a word with Johnathan @ Basingstoke Metal Finishers to take a look. Polishing is something I have done before, but for a true quality finish it is always best to speak to the pro's.

So will be back next week sometime to show how it turned out! The fun will be in trying to bolt the thing back on I suspect!
