Title: Media blasting with a mini airbrush
Post by: oldschoolace on March 31, 2015, 11:13 PM: Just wondering if anyone has tried it? Seem to be conflicting stories on the net whether its possible but i reckon with fine stuff like soda or fine aluminium oxide powder it should be doable - albeit a bit on the slow side ???

thinking of this sort of setup

What did you have in mind? frames? never had any experience with it but was looking into various forms of blasting when I had my alloy wheel refurbing business. Would be interested in any results you achieve! :daumenhoch:

I've never used the bugger but it might be a bit easier to use. You get different nozzles and a tub of media too. I got an Aldi compressor with a tank so it's not going all the time and peeing off the neighbours. They get them in Aldi quite regularly. Or there is this one on ebay:

Post by: oldschoolace on April 01, 2015, 02:44 PM: Yeah i have seen them a few times in aldi and always toy with the idea of getting their kit but never do. I dont use air tools in work and a compressor would only get used for spraying lacquer which i rarely do so it never quite justifies the purchase.

I was considering a little airbrush type as i could make a little blast box out of a clear plastic storage container. It could save a few bob on media too as it should all be trapped in the box. ;)
I know media blasting can kick up a right mess and isnt great for the old lungs too if you are not carefull.

Post by: chubby on April 01, 2015, 06:39 PM: Tried the snap on soda blaster a while back Clint. Was real good but it gets EVERYWHERE & I mean EVERYWHERE !!!!!!!!!
had no paint left on the chainring & nice finish but would say ANY type of blasting with soda needs to be in a cabinet.......

Sure I've seen an electric one somewhere too :chin:

Post by: oldschoolace on April 01, 2015, 07:06 PM: Would deffo be building a blast box, the clips i have seen on youtube look like winter blizzards :LolLolLolLol:

I've got one of those electric spray gun Rich, and did think of trying it. Doubt it would have the guts. They do more fine mists than focused cones ???

I imagine the nozzle would suffer on an airbruch but easily replaceable :)

I do know the proper blast soda is much much better to use than the cheaper commercial stuff.
Also the very very fine glass bead stuff is good to :daumenhoch:
