with a work area of 24"x20"on your Blacktooth lazer,How do I get a 4'x8' sheet down to that workable size?

To allow a 4'x8' stock to be used by a blackTooth laser system, you will need to cut the large sheet with a standard woodworking tool such as a hand saw, circular saw, table saw, jig saw, etc. Alternatively, you can purchase our very affordable 4'x8' vertical laser systems that allows a 4'x8' sheet stock.
