Adjusting Depth
Stop Rod
When adjusted correctly, the depth stop rod
ensures that the mortise is not cut too deep and
repeated mortise depths are consistent. Always
make the mortise at least an
1
⁄
8
" deeper than the
tenon to allow room for excess glue.
To adjust the depth stop rod:
1. Loosen the depth lock lever, lower the chisel
until it contacts the top of the workpiece.
2.
Adjust the depth stop using one of the meth-
ods below:
• Adjust the depth stop rod above the col-
umn to the desired depth of the mortise cut,
using a ruler, as shown in
Figure 22 and
then tighten the lock lever.
•
Another method of setting the depth stop is
to mark the depth of the mortise cut on the
side or front of the workpiece with a pencil,
lower the bottom of the chisel to the line,
as shown in
Figure 23
, then lock the depth
stop.
