Up for sale is a GRS positioning ball vise with foot treadle. The positioning ball vise is used when engraving under a microscope. It allows the work area to be centered in the microscope's field of view. Included in the sale is a foot treadle which allows the engraver to move the ball with his feet, which makes gold inlay work much easier. The bench is not included in the sale. The foot treadle is designed to bolt to the underside of the engraver's bench. The foot treadle is adjustable for different bench heights. The foot treadle can be adjusted away from the bench to accommodate longer items, like barrels. The engraving equipment belonged to an older gentleman, who is no longer able to engrave. The equipment has been sitting, unused, for about 20 years. Check out my other auctions for more engraving equipment.
