Drill Press

Overview

Drill Press

A drill press (also known as pedestal drill, pillar drill, or bench drill) is a fixed style of drill that may be mounted on a stand or bolted to the floor or workbench. A drill press consists of a base, column (or pillar), table, spindle (or quill), and drill head, usually driven by an induction motor. The head has a set of handles (usually 3) radiating from a central hub that, when turned, move the spindle and chuck vertically, parallel to the axis of the column. The table can be adjusted vertically and is generally moved by a rack and pinion; however, some older models rely on the operator to lift and reclamp the table in position. The table may also be offset from the spindle's axis and in some cases rotated to a position perpendicular to the column.

Bill of Materials

• Universal Rotor (Factor e Farm)
• Small lathe chuck (Factor e Farm)
• 1.5"x14"x1" hydraulic cylinder (Factor e Farm)
• Coupler - to go from 1-7/8 shaft to 1-1/4" shaft. 2" long on wider side, 1" long on narrower side
• [2] 3/8"x4"x6" angle, 44" long - verticals
• [4] 1/4"x1" angle, 20" long - rails for holding universal rotor to prevent it from twisting
• [2] 3/8"x4"x6" angle, 12" long
• [1] 3/4" threaded rod, 8"; [4] nuts - for top-facing end of cylinder
• [1] 3/4" threaded rod, 6"; [4] nuts - for bottom-facing end of cylinder
• [2] 1/4"x2" angle, 4" long - mounts for top-facing end of cylinder
• [2] 1/4"x2" angle, 2" long - mounts for bottom-facing end of cylinder
• [4] 1/2"x3"x15" bar - for table clamps
• [2] 1/2"x3"x7" bar - for table clamps
• [4] 1"x4" bolts - for table clamps
• [4] 1" nuts - for table clamps

Total: $150 in metal from local fab shop

Plus base:

• [2] 6"x7/8" u-channel, 3 feet long ($56)
• [2] 1/4"x2" angle, 2 foot long ($12)

Total budget: about $200 for structure, excluding chuck and Universal Rotor
