Glass Bead Abrasive Blast Cabinet
Abrasive Blast Cabinet
This is an enclosed sandblaster that uses compressed air to blast a stream of abrasive material at your workpiece.
This machine is an Eastwood Model 20027 with an Eastwood Model 30998 Dust Collector attached. The manuals can be found here http://makerspace.tulane.edu/index.php/File:Eastwood_blast_cabinet_20027.pdf http://makerspace.tulane.edu/index.php/File:Eastwood_dust_collector_30998.pdf
ALWAYS use the dust collection system when you're using the blast cabinet. The on/off switch is a round red button on the top part of the black cylinder. You will hear the vacuum start as soon as the button is pressed, and a red light will be visible in the button. The air hose on the front of the cabinet needs to be connected to the compressed air line mounted on the column in back of the cabinet. Be sure the air supply valve is in the ON position, and that the pressure gauge shows ~100 PSI.
After each extended (10 or more minutes) session, use a plastic container to catch the material that's collected at the bottom of the vacuum dust collection system. Open the door at the bottom of the black cylinder, holding the container right below the door. Bang on the black cylinder a couple of times to release all the trapped abrasive media. Re-latch the door, and recycle the abrasive media you have collected back into the blast cabinet.
Two types of abrasive material are available: glass beads from recycled bottles, and walnut shells. Glass beads are used to produce a matte finish on metal parts, and they are effective in removing rust. They can also be used to remove the gloss from PLA-printed objects, to ensure better paint adhesion. Walnut shells are for paint removal and polishing on soft metals or plastics. Ask a Ninja for help before exchanging media in the hopper.
