Setting Up the Morticer

Initial Setup
NOTE: Select the correct bush adaptor (C) 13/16” or 3/4” for the
shank of the required chisel and introduce it into the underside
of the chisel head stock. Push the bush up as far as it will go,
at the same time lining up the hole in the side of the bush and
screwing in the clamping handle (H), far enough to prevent the
bush from falling out, see fig 15-16.
Fig 15-16
Introduce the chisel into the adaptor collar, press the auger bit
up into the chuck and tighten the chuck, see fig 17, withdraw
the chuck key. Gently pinch the chisel in place by nipping tight
the clamping handle (H).

Setting the Chisel Auger Clearance
The old rule of thumb for chisel auger clearance was known as
“the one penny width”. This was achieved by introducing a
penny between the locating shoulder of the chisel and the
adaptor face, with the auger locked in place and with the chisel
pulled hard down on the auger. The penny was then removed
and the chisel pushed up to the adaptor face and, locked in
place. This established the “one penny width” between the
chisel and the auger, which for general timbers and mortice
sizes is quite adequate, see figs 18-19. Traditional morticers
normally had a cross pin in the auger mounting mandrel, to
prevent the auger being pushed back up into the chisel. The
mounting method on the newer morticers is a chuck.
Fig 18-19
It is well worth taking the extra time and care to prepare your
augers to give the correct ‘reach’ when ‘bottomed’ out in the
chuck. This will prevent the auger being pushed back towards
the chisel and altering the clearance setting, see fig 20.
