Lawyers must be sure that their expert witnesses testify in a way the jury understands clearly. It is often easy for legal counsel to understand testimony because he or she is familiar with it but they must remember that this is the first time jurors have heard it. For example, the equipment and machinery expert witness must be able to testify on the facts, concepts, and technical language in an understandable way on subjects that may include woodworking machinery (radial blades, bandsaws, debarkers, conveyors, lumber stackers, resaws, planers, etc.) and metalworking machinery (cutoff saws, lathes, grinders, sand blasters, punch presses, tipping machines, drills, etc.)
