Setting Up the Morticer
11
The mortise will generate a lot of ‘grip’ on the chisel,
especially the first cut, or if the timber is a little green.
Make sure you use the table clamp assembly to help
control the timber during the raise operation of the
morticer.
Coupled with the depth stop on the same assembly is
the head stock rise limiter. This limits the rise of the head
stock /chisel to a convenient distance above the work by
the use of a locking collar positioned above the stop
finger on the side of the head stock. The travel of this
assembly is then restricted to your chosen setting rather
than having to return it to the top of the slide each time.
General Notes
When the chisel is tightened in the machine it must
normally be square to the back fence. The easiest way to
achieve this is to bring the head stock down to bring the
chisel as close to the table as possible, set a square against
the back fence and set the side of the chisel against the
square and clamp tight. (Remember to have the chip
ejection slot in the chisel to the side from which you will
cut the mortice).
Setting the Chisel Square
Quick Setting of the Mortice Depth
chisel, position the head stock so that the chisel points or
the auger point are at the depth required, raise the depth
stop collar to the underside of the head stock and tighten
gently. Recheck the depth of the chisel point, if it is
satisfactory tighten securely, if not it can be gently
‘nudged’ down the column with the head stock, then
tighten. Reposition the operating handle to give the
most comfortable position and purchase on the lever,
over the full distance of the movement you have just set.
Head Stock Rise Adjustment
Put a mark on an easily accessible end of the work piece
to be mortised, at the depth you require. Pull the head
stock down, and put the end of the timber against the
