Stroke, hit and hand speed
A mechanical vocabulary for comparing machines without pretending one setting suits every artistStroke length is easy to publish and easy to overread. Motor behavior, give, balance, voltage, grouping, cartridge and the artist's hand determine how that motion reaches the skin.
01
Stroke
Length changes the motion, not the result by itself
Shorter stroke is commonly associated with softer work and longer stroke with decisive lining, but motor torque, cam profile and technique can reverse a simplistic rule.
- Compare
- Use the same grouping, cartridge and practice medium.
- Record
- Note hand speed, voltage and needle depth with each machine.
02
Hit and give
Two 4.2 mm machines can feel unrelated
Mechanical compliance, drive profile and motor response change how the machine loads and recovers. Adjustable give can widen the range while adding another setting to reproduce.
- Fixed behavior
- Useful when the artist wants the machine to disappear into habit.
- Adjustment
- Useful when the artist can name what each change solves.
03
The hand
Ergonomics remain part of performance
Grip diameter, center of mass, battery height and vibration affect control over a long appointment. Published weight alone does not describe balance.
- Trial
- Work at session length, not for five minutes.
- Barrier
- Test the wrapped machine and normal grip setup.
