Anyone have experience in accurately cutting 1/8" thick acrylic Plexiglas
(Perspex) for LED displays?

Use the score-and-snap method. Purchase a scoring tool from any of
the big box stores or many hardware stores. This tool has a backward
pointing scoring point and cuts a 90 deg Vee.

Score the plastic along a straightedge to about 1/3 the thickness.
That's about 3 passes with the scoring tool.

Position the plastic on a counter or bench with a sharp edge, locate
the score over the edge. Place your palm on the plastic and firmly
push down. The acrylic will cleanly snap. If you get a ragged break
or a chunk of plastic remains on one end, you didn't score deeply
enough.
