Keep the leading edge of the chisel flat onto the workpiece (i.e. Bottom surface of the
mortis/recess). Move the chisel forward and out to form the recess to the required
diameter and depth.
Note:
FOR SAFETY REASONS NOVA STRONGLY ADVISE AGAIST USING ANY OTHER TOOL
APART FROM THE NOVA DOVETAIL CHISEL AND SKEW SCRAPER CHISEL.
Recommended Diameter of the recess
The suitable mortise/recess diameter is dependent on the accessory jaw that is
mounted on the chuck.
For the standard PRO-TEK 50mm jaws that is included in the package:
The mortis/recess diameter should be ranging anywhere in between 55mm ~ 65mm
(2.16” – 2.55”)
General rule to determine the suitable diameter and depth of the recess:
1.
Recess diameter should at least be 5mm 3/16” bigger than the outer diameter
of the jaws when completely contracted on the chuck.
2.
Recess diameter should at least be 5mm or 3/16” smaller than the outer
diameter of the jaws when completely expanded on the chuck.
