Media blasting with a mini airbrush

[oldschoolace]

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

Looks very interesting Clint, it would be interesting to see what effect it had on tuffs . 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!

I was thinking about smaller parts like chainrings, calipers etc. I think the diameter of spray they put out is only 4 or 5 mm so larger stuff would take a good while. Might try and pick one up on the cheap have experiment

Using baking soda it should work well.

I followed this link and built my own media blaster, I do have a compressor at home, but it does work really well for cleaning stuff.

yeah guess this's the same GarageNightTV vid  - 'venturi effekt' i.e. clunky duster gun route

I got one of these a while back from Aldi:



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:

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.

I think if you use it in an airgun it will just media blast the nozzle away

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

Best ask your brother about this one chum

Would deffo be building a blast box, the clips i have seen on youtube look like winter blizzards 

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

Great idea there wonder how long it would take to do a set of spray bombed tuffs or what would you guys recommend on doing?
