Here's a simple way to clean up the rough edges of tablesaw cuts in acrylic
Rout away rough cuts in acrylic

If you get too much chipping when cutting the acrylic panes on your tablesaw, here's a way around the problem: Using the finest-tooth blade you have, cut 4-14 x6-14 " blanks. Then cut a piece of 34 "-thick scrap to 4x6". One at a time, adhere the blanks to the scrap with double-faced tape, centering the blank on the scrap. Chuck a flush-trim bit in your table-mounted router and trim the blanks to finished size.
