CONTROLLED DEPTH DRILLING
When it is necessary to control quill extension,
as in drilling to predetermined depth, or
mortising, extend the quill until the drill point
touches the work. Turn the depth control dial
(Fig. 52) clockwise to the setting desired and
secure with the feed stop. The quill will then
extend that further amount. To hold the quill in
any extended position use the quill lock.
PARALLEL DRILLING
The rip fence is an excellent guide for
maintaining edge distance on a series of equal
holes. (Fig. 53) Lock the fence so that the
distance from the side of the fence to the drill
point is equal to the distance from the edge of
the work to the center of the hole. On
SHOPSMITH this is done very accurately by
locking the fence in an approximate position
and then using the table height lever as a
forward feed mechanism to make the final
critical adjustment.
