Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an AI agent to recognise a spindle, identify its rotational role and interfaces, assess its condition, and determine compatible and permissible uses.
A spindle is a rod or shaft that rotates about its longitudinal axis to perform a task such as twisting fibres into yarn or carrying and rotating a tool or workpiece.
It can be Classify the spindle's application and establish the boundary of the item being assessed.; Check proposed tools, workpieces, bobbins, or whorls against documented attachment and loading requirements.; Assess runout, alignment, retention, and rotation using methods appropriate to the spindle type.; Determine whether a proposed speed, direction, and load lie within documented operating limits.; Identify applicable cleaning, lubrication, balancing, repair, or replacement actions.; Permit, restrict, or defer installation and operation according to condition evidence and host-equipment requirements..
Distinguishing features
Establish whether the object has an intended rotational axis and directly carries or engages a tool, workpiece, or textile strand; a merely spindle-shaped object does not satisfy this provisional scope.
Distinguish the spindle from a general transmission shaft by recording its direct role at the working or material-handling interface.
Distinguish the spindle from a chuck, collet, bobbin, or whorl by identifying which component provides the axial body and which attaches to it.
Determine whether 'spindle' names the rotating member alone or an assembly containing bearings, housing, and possibly a motor.
Separate textile and machine-tool applications through their actual engagement mechanism rather than assigning machining properties to every spindle.

Spindle identity and application Establishes which physical sense of spindle is represented and what belongs to the assessed item.
The unqualified name can refer to substantially different implements and assemblies.
Working role
Identifies what the spindle rotates or engages and why.
Application identification
Record evidence for a textile, tool-carrying, workpiece-carrying, or other spindle role.
- What does this spindle directly carry or engage during its intended operation? definition
- Which registry reference, technical drawing, or manufacturer description establishes this sense of spindle? provenance
Assembly membership
Separates the rotating member from its accessories and surrounding equipment.
Spindle item boundary
Identify whether bearings, housing, motor, whorl, bobbin, or retention mechanisms belong to the spindle item.
- Does the identified item include only the axial member or also its support, drive, and retention components? boundary
- Which attached parts are replaceable accessories represented by neighbouring models? boundary
Geometry and engagement Describes the spindle axis, locating surfaces, and interfaces with the things it carries.
Spindle suitability depends on physical fit, retention, and location relative to its axis.
Axis and locating surfaces
Captures geometry used to locate and support the spindle.
Functional geometry
Record relevant lengths, diameters, bores, tapers, and reference surfaces without assuming a machine-tool configuration.
- Which dimensions and surfaces establish the spindle's working axis and fit within its support? measurement
- Which drawing or interface specification defines the dimensional tolerances and datums? provenance
Carried-item retention
Captures how the spindle engages tools, workpieces, or textile-related attachments.
Attachment compatibility
Record the actual engagement and retention mechanism, including application-specific restrictions.
- What feature retains the tool, workpiece, bobbin, whorl, or yarn, and how is correct engagement recognised? definition
- What interface evidence and retention checks are required before accepting a proposed attachment? action
Rotation and loading Connects the spindle's drive and support arrangement to its permissible operating conditions.
A spindle's useful operation depends on the combination of rotation, support, and attached load.
Drive and support
Identifies how torque enters the spindle and how the spindle is supported.
Rotation path
Record manual or powered drive, support arrangement, and the boundary with host controls.
- How is rotation imparted, and what supports or suspends the spindle during use? definition
- Which speed, direction, and stopping functions belong to the spindle assembly and which belong to its host? boundary
Operating envelope
Records the limits applicable to the spindle and its configured attachments.
Combined operating limits
Assess speed and loading together, preserving the configuration and evidence behind each limit.
- What speed, torque, axial load, radial load, attached mass, and overhang limits are documented for this configuration? measurement
- Does the proposed operation satisfy both spindle limits and the limits of its attachment and support arrangement? action
Condition and service decisions Organises spindle-specific observations and the actions they justify.
Fit and nominal speed do not establish whether a worn, bent, poorly retained, or incorrectly supported spindle is usable.
Rotation and retention condition
Assesses the working axis, locating surfaces, and retention features using application-appropriate checks.
Condition evidence
Record measured or observed runout, play, vibration, surface damage, and retention defects with their assessment conditions.
- What runout, play, vibration, or visible damage was observed, at which locations and under what conditions? measurement
- Which application-specific acceptance criteria determine whether those observations restrict use? provenance
Service and return to use
Links spindle construction and condition to appropriate intervention and verification.
Permissible intervention
Identify documented service actions and the evidence needed before the spindle returns to operation.
- What cleaning, lubrication, attachment adjustment, bearing service, balancing, or replacement is applicable to this spindle design? action
- What isolation, retention, alignment, and trial-operation checks are required by the applicable instructions before return to use? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- shaft - Shaft is the broader mechanical category; spindle usually denotes a shaft serving a particular working function, such as carrying a tool or workpiece.
- spindle whorl - A whorl is a weighted component fitted to some textile spindles to influence their rotation, rather than the complete spindle.
- bobbin - A bobbin holds wound yarn or thread and may be carried on a spindle; it is not the spindle itself.
- chuck - A chuck grips a tool or workpiece and may be mounted on a machine spindle.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of spindle this model covers, and on what evidence? provenance
What the second pass must settle
- Does vr.tr.spindle denote a textile implement, a machine spindle, a fixed architectural member, or a broader physical category according to its originating registry record?
- Does an existing Vercy world model already own the intended spindle concept, requiring a link instead of a separate publication?
- Which spindle subtypes belong within this entry, and which application distinctions should remain conditional layers rather than separate registered things?
- Which authoritative sources establish the relevant attachment standards, issuing bodies, operating limits, and inspection methods for the confirmed spindle sense?
- Which failure modes, maintenance requirements, and certification obligations apply to the spindle itself rather than solely to its host equipment?
