Popular woodworking just sent out an e-mail about a new device that Woodworking tool manufactures have been working on called Saw Drop. A device that drops the blade below the table WITHOUT blade damage. It also can tell the difference between wet wood and flesh.
Don't think I'm allowed to post a link to Pop Wood blog but do a search there for
Saw Drop.
