I found a great place for plexi glass scraps and other plastic sheet goods, and brought home a bunch of random pieces. With some of those pieces made a lettuce knife.
Step 1: Gather your materials
You need clamps, CA adhesive (Cyanoacrylate (super glue)), scrap plexi glass wet sand paper belt/disc/drum sander or maybe a dremel, plastic polish, buffing wheel.
*****UPDATE ON GLUEUP****
straight acetone works better for glue up of plexiglass, not to mention MUCH MUCH CHEAPER THAN CA adhesive...
just make sure you clamp it good.
