Hi, could someone recommend a method of attaching plastic sheets 3/16" thick to the engraver/router table. Vacuum is out of the question IMO as I need to cut through the material. (Actually I need to make grooved 20"x 1.5" parts out of the 20"x30" sheet). Without holding the material down the groove depth varies as the spiral flute router bit tends to lift the sheet. I'm fairly new to this so any thoughts would be appreciated. Thanks,
Mark.
