I recommend taping a piece of clear plastic on the inside of your windo. This is cheaper and easier to replace than the window. I use glass bead almost exclusively in the cabinet. I bought walnut shell but it is not very effective, thus it sits in the bag. If I need to do some grit blasting, I use a cheap siphon unit outdoors. The grit is cheap, glass bead is not. Do not put you blaster in the area where you do any assembly of parts. The beads do get out of the cabinet and in the air (a bit). Put it in the back side of your work area with plenty of lighting.
