Drill Press Plans

The
Precision Mini Drill Press is
designed to handle up to 1/4"
(.250") drill bits. It fills a
need for a drill press between
my Micro Drill Press and the
regular commercial 1/2" to
5/8" bench drill presses. The
unit is machined primarily
from aluminum alloy bar stock
and drill rod and the base is
machined from a cast iron
lifting weight. The drill
press features an adjustable
quill depth stop, quill lock,
a shop made electro-magnetic
base/table and provisions for
a 2" travel dial drilling
depth indicator for high
precision drilling depth.
It is powered by a high torque
2-1/2" diameter permanent
magnet field DC ball bearing
motor. Speed can be adjusted
using a variable voltage DC
power supply, and/or also by
choosing one of three steps on
the pulleys.
There are a lot of other ways
that you can think of to power
yours. One is to use a
universal type AC motor such
as on a sewing machine and a
light dimmer to vary the RPM.
The quill feed is by standard
rack and pinion gear.
The
plans set consists of 10
sheets of drawings and 1 sheet
of construction notes.
