=1 Process=
 
*Cut Angle 0.125" x 1.5" x 1.5"
 
To 14 pieces of 360mm length
 
To 10 pieces of 160mm length
 
To 1 piece of 60mm length
 
*Cut Square Tube 0.125" x 1.5" x 1.5"
 
To 1 piece of 200mm length
 
*Cut Flat Bar 0.125" x 6" x X
 
*Drill Angle Template
 
60mm long, 0.125" x 1.5" x 1.5" steel angle.
 
Use pilot bit. Differentiate the 2 holes as A and B. When looking at the angle's inner perspective, hole A should be up and to the left of hole B.
 
ANGLE HOLE A - Mark and drill hole A on one angle side, 20mm from the inner joining edge of angle, close to the end of the angle.
 
ANGLE HOLE B - Mark and drill hole B on the other angle side, 20 from the inner joining edge of angle, 40mm apart (distance is angle-parallel) from hole A.
 
*Tube Template
 
0.125" x 1.5" x 1.5" x 180mm steel tube.
 
All holes drilled with only pilot bit. Keep angle template usage consistent by keeping its 2 tube contact faces the same for all holes for a given surface. Ensure tube is on flat surface. Ensure tube template usage consistency.
 
TEMPLATE REFERENCE HOLE Use angle template hole A to drill reference hole near end of tube.
 
TEMPLATE MOTOR HOLE Mark and drill 8mm tube-parallel from reference hole.
 
TEMPLATE STEPPER HOLES Mark 15.5mm tube-parallel from reference hole then drill 2 holes each 15.5mm tube-perpendicular from mark.
 
TEMPLATE SHAFT HOLE Mark 70mm tube-parallel from reference hole then drill 1 hole at mark using angle template hole A.
 
TEMPLATE FRAME HOLE Mark 170mm tube-parallel from reference hole then drill 1 hole at mark using angle template hole A.
 
TEMPLATE ANGLE HOLE Drill 1 hole using angle template hole B while hole A is set to the template shaft hole with rod.
 
*X Angles (aka the steel angle pieces that go horizontally from side to side of the circuit mill)
 
0.125" x 1.5" x 1.5" x 360mm steel angle (4)
 
Drill reference, frame, and frame angle holes in all.
 
Drill shaft holes in 2.
 
Drill stepper holes in 1.
 
0.125" x 1.5" x 1.5" x 160mm steel angle (7)
 
Drill reference, shaft, and shaft angle holes in all.
 
Drill stepper holes in 1.
 
Drill motor holes in 1.
 
*Y Angles (aka the steel angle pieces that go horizontally front to back of the circuit mill)
 
0.125" x 1.5" x 1.5" x 360mm steel angle (4)
 
Drill reference, frame, and frame angle holes in all.
 
*Z Angles (aka the steel angle pieces that are oriented vertically upwards)
 
0.125" x 1.5" x 1.5" x 360mm steel angle (6)
 
Drill reference and frame holes in all.
 
Drill frame angle holes in 4.
 
Drill shaft holes in 2.
 
Drill stepper holes in 1 as if the upper shaft hole was the reference hole.
 
Drill new shaft holes in 2 as if the upper shaft hole was the reference hole.
 
*Sleeve Bearing (reduces friction between the pair of support shafts and the moving platform for each axis)
 
Drill the 12 sleeve bearings through the XYZ setup to achieve alignment.
 
*Leadscrew Nut (converts rotary motion of the leadscrew into linear motion where the nut travels along the axis of the leadscrew)
 
Drill the 3 leadscrew nuts through the XYZ setup to achieve alignment.
 
*Plates (used to increase the rigidity of the pair of moving angles in each axis setup)
 
Drill the 3 plates through the XYZ axes setup to achieve alignment.
