This blast cabinet is designed for high-use media blasting operations, where air flow up to 25 CFM and air pressure up to 120 PSI can be used. Air pressure is fully adjustable with a control panel air pressure regulator. A fixed blasting gun and a hand-held blasting gun are included in this machine. Blasting operations through a hand-held blast gun or fixed gun are controlled by a foot valve and control panel. Internal size 24" x 37".
A membership or day pass is required to access the Metal Shop.
The Shop Safety Class Metal 1 (https://www.openworksbmore.org/schedule/) is required before operating the Blast Cabinet.
The blast cabinet does not require a machine reservation and is available on a first-come first-serve basis.

When media blasting thin materials made of aluminum, copper, brass, wood, or other delicate parts, select correct media and begin blasting at low pressure, such as 45 PSI. Next, slowly increase air pressure until you achieve finish required. When using some types of glass bead media, you may have to keep operating pressure between 50–80 PSI or media will break down prematurely. Some media like silicon carbide and aluminium oxide can withstand pressures of up to 120 PSI on this machine; however, most media blasting operations should occur at 80 PSI.
Loading only enough media for job at hand will help you prevent over-using or having to screen excess media. Typically use just enough media to cover suction tube opening by 6".
Install correct blast tip in position in gun, if not already installed.
Place properly-cleaned workpiece into blast cabinet, close doors, then move latches until they are completely locked.
Toggle POWER, LIGHT, and DUST switches to ON position to start dust collector and to turn work lights ON.
Point blast gun tip at workpiece in a direction where ricochetting spray of abrasive will not contact windows.
Press foot pedal for fixed gun blasting, or pull hand-held blast gun trigger and media will begin spraying from blast tip. Depending on blasting gun selection, move workpiece or blast gun slowly in methodical circular motion.
For most media blasting operations, maintain blast distance of six inches. Maintain blasting spray at 45°–60° angle from workpiece so media will ricochet off and not directly impact lights or viewing window. Doing this will help maintain workpiece visibility and make protective viewing window film and media last longer. Do not point gun or hold workpiece so spray pattern is perpendicular or 90°degrees to surface.
