"the making of needles" Materials correct answers- Flat Needle Bar
-round needle bar
- eye loop
-drill gauge: tightens needle
- souder
Making of needles process correct answers-clean and sterilize after making needles
-Tin the soldering iron
-drop the needle into Jig, lightly tap to ensure all needles are even ( pointed side should be down )
-drop a small amount of flux at the end of the needle groupings, tap with soldering iron.
Diameter of a needle correct answersAffects ink flow and puncture of the skin
Tapers
- Long Taper : Good for Lining
- Short Taper : Good for color
Coil Machine how does it work correct answersUses magnets to power machine which moves the
armature bar and needles towards the coil.
This pulls the needle into the skin, breaking the circuit, causing the needle to go back into the machine
Coil Machine : Electromagnet ON - coils are not charged, the armature bar is up, pulling the needle up
correct answersCoil Machine : Electromagnet OFF- coils are charged, pulling the armature bar down,
pulling the needle down
Tuning - voltage correct answers-4 volts for shading
, -5.5 volts for lining
Rotary
7-8 for either beginner lining or shading, 9-10 for lining
Tuning- CPs/Hertz correct answers- Cycle per second
- 130 for lining
-120 for shading
How to adjust CPs/Hertz correct answers- Adjust by moving contact screw
- Increase : moving closer to the front spring, this also shortens the stroke.
- Decrease: moving further from the front spring, this lengthens the stroke
Tuning: Stroke correct answers-lining, shorter stoke 3mm
-Shading, grey wash, med stoke 3.5mm
-packing color, longer stroke, 4mm
Tuning: Duty correct answersMeasures how long the needle is in the skin
Duty below 50 correct answersMachine is spending more time off than on during a cycle
This means the needle is spending too much time extended out into the skin, causing extra trauma to
the skin
Duty above 50 correct answersThe needle is spending too much time in the tube, causing the skin to not
get enough ink
How to Adjust the Duty correct answersSwinging the armature bar out and lightly bending the back
spring
