Forming a Mortis/Recess
A mortis/recess is a hollowed-out portion with which the jaws sit in. A tapered side
wall with angles of approximately between 75~80degrees (one side) is recommended
for better gripping strength and safety.
A dovetail profiled mortis/recess to match the NOVA jaws can be easily created by
using the NOVA dovetail chisel however a dovetail can be formed with any other
appropriate type of chisels. The diagram shows the dovetail formation process using
a NOVA dovetail chisel:
On the side where you would
like to form a dovetail recess:
1.
Form a recess with the
desired diameter onto the
workpiece using any
preferred tool
2.
Push the NOVA dovetail
chisel flat onto the bottom
surface of the recess
3.
Drag the dovetail chisel
towards the side wall (With
the angled side facing
towards the side wall as
shown in the illustration)
to form the dovetail
profile.
Note:
Refer to the NOVA dovetail
chisel manual for a more
detailed information of how to
use the chisel.
If You do not own a NOVA Dovetail Chisel
The dovetail angles on the jaws are originally designed to fit the standard skew chisel.
The skew chisel will naturally form the dovetail angle needed for the dovetail.
Image below illustrates the profile of a typical skew chisel profile and how to correctly
use it to cut a dovetail recess in the workpiece:
