Introduce the chisel into the adaptor collar, press the auger up into the chuck, tighten the
chuck and withdraw the chuck key. Gently pinch the chisel in place by finger tightening the
clamping bolt. (See figs 8,9)

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. Traditional mortisers
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 mortisers is a chuck. 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 A)
