The MCE-100 drill guide is made up of a clamp to securely hold a
mortise cylinder when drilling and tapping the required mounting
holes. There is also the drill guide plate (gray) and tapping plate
(red). Also included is the #29 drill bit with a stop and a 8-32 tap
with a handle.

Install the proper cam driver
in place of the lock cam.
Use the screws provided,
the original screws will be
too short.
Install the drill guide plate
(gray plate) on the cylinder
clamp. Do not tighten the
mounting screws
( see arrows ) at this time.
The drive cam must be
installed at this time, it is
used to center the
mounting holes.
There are two ball bearing
detents inside the cylinder
clamp. The detents will
center the mortise cylinder
in the clamp.

Ball bearing detent
one on each side

Make sure the mortise
cylinder bottoms on the drill
guide. There should be no
space between the clamp
and the drill guide.
Rotate the key and make
sure the cylinder rotates
freely on the drill guide.
This will insure that
everything will be aligned
when drilling.

Once the cylinder rotates
freely in the drill guide
tighten the two cap screws.
After the guide has been
tightened, check to make
sure the cylinder still turns
free, if not, readjust. This
step is important to insure
a good working
modification.

Drill both holes with a #29
drill bit. Adjust the stop on
the drill bit so the hole is
drilled to a depth of about
3/4” ( Adjust the stop so it is
1-1/4” above the tip of the
drill bit.) This will allow
plenty of room for to tap to
the depth needed without
bottoming out.

Remove the drill guide from
the cylinder clamp. Do not
remove the mortise cylinder
at this time.
Tighten the mortise cylinder
in the clamp unit.

Install the tap guide on the
clamp. The cap screws
should be loose to allow the
guide to float. This will allow
the guide to self-align.

Be sure to lube tap with a
cutting oil prior to tapping
holes.
With the use of the red tap
guide tap the first hole.
Back out the tap frequently
to clear chips from work.

Loosen the cap screw on
the cylinder vise and
remove the mortise
cylinder.
Set the plug extender on
the cam driver.
These are the finished
mounting holes for the
extension unit.

The plug extension will just
set on the cam driver, it is
captured by the housing
when installed.
Put the housing over the
extension and make sure
the plug extension mates
with the cylinder plug, see
arrow.
Use the supplied 8-32 flat
head screws to attach the
extension unit to the mortise
cylinder.
The mortise extension unit
Is designed to accept a
Kaba Ilco brand cam. The
use of other brands may
not fit correctly and cause
a problem with proper
operation.
That’s all there is to it!
