Portable media blaster - video

[tonyfoale]

I built one almost identical. The only problem is that it consumes the media very quickly so you are forever refilling it. Otherwise it works great. I have a blasting cabinet so I do not need a portable device for most media but I use it now only for baking soda which is basically a one use only type of media and so I do not want to load up the cabinet with it because you can quickly end up with a load of broken up soda which does not work well. A lot of the broken soda is sucked out by the ventilation.
