Making your own sand blaster

Sand BlasterWhile reading English Mechanics, I couldn't help photographing this delight - instructions for making your own sandblasting set-up using a grinder fitted with a wire wheel.

Basically, you drop the blasting medium down a funnel onto to the wheel which flings it at the item to be blasted. Health & Safety isn't forgotten with a see-through panel to protect the operator. I bet he needed it too - the media will get suck in the bristles and be flung out everywhere that the wheel isn't guarded.

The thing that strikes me about this is how incredibly messy the process would be. Did anyone every try this ?

Nowadays we do the whole thing in a sealed cabinet using compressed air. The mess is contained and the media can be reused until it wears smooth. Still, it shows ingenuity which is what made this nation great !
