ramy 3 Posted October 5, 2010 Looking to try my hand at this, what is the best medium to use for sandblasting glass? Share this post Link to post Share on other sites
rickybh 0 Posted December 4, 2010 I use Aluminum Oxide (100 grit) at 30 psi and just plain ordinary vinyl. http://i130.photobucket.com/albums/p276/rickybh114/Sandblast/DSC01506.jpg[/img] http://i130.photobucket.com/albums/p276/rickybh114/Sandblast/DSC01507.jpg[/img] Share this post Link to post Share on other sites

txpatrol 1 Posted December 5, 2010 I use Aluminum Oxide (100 grit) at 30 psi and just plain ordinary vinyl. What do you use for a gun? I've been using an air eraser with 200 grit AO because that's all that will fit in the air eraser. I tried with 70 grit and it just clogs it up. I'm waiting for a deal to come around on a cabinet so I can just get it over with. Share this post Link to post Share on other sites
RocketRollinSX 2 Posted December 5, 2010 I have a small blast cabinet from Harbor Freight. Not the nicest thing out there but it gets the job done. I checked this one out at Tractor Supply the other day ant it looks decent for the price. http://www.tractorsupply.com/tools/sandblasting-tools-accessories/black-bull-abrasive-blast-cabinet-3951103 220 Grit AO is the way to go, leave a nice smooth frost on the glass. Got mine from Harbor Freight. Share this post Link to post Share on other sites
prototype66 20 Posted December 6, 2010 so really you could get started etching for just under $300 or so! and a bit of practice... Share this post Link to post Share on other sites

txpatrol 1 Posted December 6, 2010 so really you could get started etching for just under $300 or so! and a bit of practice... If you already have a compressor, yes. I use the air eraser without a cabinet and do just fine....although you usually end up with a little grit in your teeth...and hair...and shirt. It uses such an insignificant amount of media that it's really not worth trying to recycle it. I use maybe half a tablespoon off 200 to do a beer mug. With a smaller blaster, like the eraser, a cheapo compressor will do just fine. For the bigger setups like a pot or gravity feed gun, you're going to need a much bigger compressor. I personally use an 80-gallon emglo that's rated for 17cfm @ 170psi.....but that's just a tad overkill. Share this post Link to post Share on other sites
prototype66 20 Posted December 6, 2010 dumb question ....would an airbrush compressor be enough or would that be too small. Share this post Link to post Share on other sites
cutme 5 Posted December 6, 2010 "I use the air eraser without a cabinet and do just fine....although you usually end up with a little grit in your teeth...and hair...and shirt."... AND LUNGS! DO NOT SANDBLAST WITHOUT A FRESH AIR MASK! FACEMASK RESPIRATORS ARE NOT RATED FOR SANDBLASTING. also ao has a static electricity problem that makes it hard to see what you are doing. silicon carbide is a little more expensive, but worth it. no static build up and discharge and it doesn't break down like ao. bb Share this post Link to post Share on other sites
