The Deluxe Engraver is a two-dimensional pantograph-engraving machine. It is equipped with a tracing stylus and a diamond tip-engraving stylus. By changing the ratios on the pantograph arms you can engrave letters 1/4" tall on the 2-1/2 setting to 3/32" tall on the 6 ratio setting. Letter blanks are 1-1/4" tall and the letter is 5/8" tall. Note that the ratio setting on the pantograph arms must always be the same. Use only hand tight pressure on all knobs on this machine.
