Best thing to do to your blasting cabinet.

Gotta leaky H/F cabinet also, went to Lowes and picked up an 18" enclosed flourecent fixture. Don't remember the price but it was cheap. As far as dust collection I googled DIY dust collector and found a neat set up that won't ruin your shop vac. Run 1" pvc into a 5 gal bucket with a lid, run the pipe through the lid with fittings to keep air tight about 4" short of the bottom. Add 3" of water and another male adapter in the top that goes to the vac. Basically using the bucket as a liquid filter system. Again also cheap and works great.
