 A sturdy surface with adequate lighting
Make use of a heavy workbench or suitable solid furniture to support this
equipment, workpiece, and any additional equipment and supplies. Adequate
lighting allows clear sight, and may help prevent accidents and reduce fatigue.
Placement of this engraving system on the bench is solely user preference and
may be determined by left or right hand use during operation.
 Workholding device or material
For best results, using a workholding device or material is highly recommended.
Properly secure the workpiece to ensure user safety and to guard the piece from
damage while working. GRS manufactures several sizes and types of workholding
devices, such as the MagnaBlock, Positioning Vise, MicroBlock vise, Thermo-Loc
material, and the BenchMate™.
