The two photos above show the front part of the cylindrical attachment removed, and a circular holder clamped onto the central spar. By clamping on the central position on the spar, maximum rigidity is maintained. This holder can be swivelled around on its axix if further alignment is required. A variety of different shape pegs (made locally by an engineer) hold the items. I use these for clamping a variety of trays and dishes, round, square or rectangular. Additional clamping can be gained by 'g clamps'
This jig (left) is used for holding flat plates, the standard stock item is supplied with just one central vice, but for busy workshops who may require to double up engraving, then it can be doubled up (as illustrated) Remember the NH machine has the ability to run up to four diamonds in a row. The jig on the right has been modified to accept items that are up to approximately 20mm in height
Instead of having three spreader legs to hold large circular items i.e. round trays or salvers, it is easy to insert the 3 jaw chuck insert to hold a medal
The Kirba diamond is modified as follows. The standard NH air piston on the left as standard takes a 1/8th diameter diamond. Kirba drill this out to 5mm so the insert on the right can be used. This is a spring loaded diamond. This definitely gives a better engraving on the items I engrave. See the section on diamonds for more gen
