Hi,

A bit pricey but has any one used this before:

Seems pretty cool.  Again a bit pricey but cool.

Most of what you're paying for is the fancy grit dispensing system and downdraft vacuum tray.  Several airbrush manufacturers make blaster/air-erasers for much lower prices.  I have an old one from Badger that they called a "Hobby Abrasive Gun" - came with a basic air-brush type blaster and very fine grit aluminum oxide grit.  I used it for everything from stripping die-casts to etching glass (using a stencil ofc). You can still get one on Amazon for around $35.00

Hi,

Nice tip, thank you sir.

After looking at the MicroMark unit, I am thinking you can even diy the blasting bed using two plastic totes that nest inside each other - one deep, one shallow. On the shallow one cut a hole in the side for a shop vac hose, cut the bottom out and install a fine mesh screen, then seal the lid on with silicone caulk. Flip it over and set the bigger one over it with one long side and part of the bottom cut out to act as the containment for the abrasive particles. Connect the shop vac hose and blast away.

I own one of those Badger sandblasting guns and have used few times for projects. The problem is containment of the blasting media.  I ended up using a plastic storage container to blast into.  Then the blast media needs to be sifted to be reused.
