Re: Twin Sherman Vent 18x18x24's
Get a flat, un-glazed tile. Or if you can't find one, get a tile with a fairly flat, un-glazed back. After you cut your glass, put the sheets in the bathtub with a couple of inches of water in it and submerge the glass. Use the tile like an emory board and run it (make sure the tile is wet too) along all cut edges. This will dull the edge and put an end to the cut fingers. I have a grinder, but the old ceramic "sanding" works just as well to dull edges. The grinder allows me to make nifty door handles and curvy stuff when I feel so inclined.
For a buck your fingers will thank you. Glass is gonna cut you- that's just its higher purpose.
Vivs look great!
There's Bears in these here Woods. Wouldn't have it any other way.
