Precision
Mini 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.
