My fossil prep has so far been limited to hand tools - brushes, needles in pin vises, sharp blades, and a rotary Dremel for sanding and polishing. I’ve been using the Dremel outside with an N95 mask and eye protection. I’d like to be able to work inside on rainy days and in the winter (I live in Iowa, so it gets pretty cold). Right now, to move inside, I would need some sort of cabinet to handle the dust I kick up from the Dremel. But thinking ahead, I’d like the cabinet to be able to handle air abrasives also. I’m deciding between making my own cabinet and buying one. I like the look of the Vaniman Problast cabinet, but it seems to handle only media 25 microns and up. I think this precludes using baking soda, unless it’s possible to mod the cabinet. The Vaniman cabinet also seems to recycle the media, which wouldn’t be what I want for getting rid of dust from my Dremel work. So, I guess my questions are: Do I need to decide between a cabinet that recycles media and one that clears it all away? If I do decide to build my own cabinet, does anyone have a recommendation for how to do this? what questions am I not asking that I should be? Thanks much.

This tool is probably well known to most, but I just discovered it. So I thought I would share. When working with a pin vice under the dissecting scope, I'm always having to lean down and blow away dust. These little non-aerosol dust blowers are available on-line for between $5 & $10. I prefer the one with a brass tip and one-way valve (it takes air from one end and blows from the other). Search online as "dust blower" or "dust blower bulb". FWIW...
