8 documented faults under Mechanical & Motion. Each entry sets out the symptom as owners report it, the most likely cause, the checks that confirm or rule it out, and whether the repair is worth doing — compiled and cross-checked from manufacturer documentation and owner reports, with sources listed on every page.
Documented faults
- Record Power DML250
The DML250 mini lathe vibrates or shakes noticeably while turning, rather than running smoothly
Record Power's own troubleshooting table names five distinct causes for lathe vibration, from a simple out-of-balance workpiece to worn spindle bearings — not one single fault
Mechanical & Motion 2026-09-22 - Record Power CL4
The lathe stops mid-turn and the main spindle bearing is locked solid, with no give when turned by hand
The main spindle bearing has seized inside its race — wear, contamination or age — rather than a fault in the motor or drive belt
Mechanical & Motion 2026-09-21 - DeWalt DCN660
The nailer won't drive fasteners — the trigger does nothing, or it fires the motor but no nail comes out
DeWalt splits this into distinct stages rather than one fault — trigger lock-off left engaged, a flat battery, an unreleased contact trip or mode selector, or a jam in the nosepiece or magazine — and the worklights next to the trigger indicate which
Mechanical & Motion 2026-09-16 - Record Power CL2
The lathe stops during turning and the main spindle bearing is locked solid, refusing to turn
The main bearing has seized on the spindle, usually from wear or contamination inside the bearing race, rather than a fault elsewhere in the drive
Mechanical & Motion 2026-09-07 - Record Power CL3
Too much play in the headstock spindle, with vibration that makes the lathe difficult to turn on
Headstock bearing clearance opening up with use — on the CL3 the bearings are designed to be adjusted to take up that wear, not replaced at the first sign of movement
Mechanical & Motion 2026-09-01 - Triton TRA001
Router won't wind up and down smoothly under a table — the winder handle feels heavy or jams, and the body drops a few millimetres the moment the plunge lock is released
Table-mode setup rather than a failed part: with the plunge return spring out, the winder lifts the machine's full weight through a rack and pinion that has several millimetres of backlash, and downward pressure on the handle racks the plunge columns and binds them
Mechanical & Motion 2026-08-23 - Creality Ender 3
Prints develop sudden sideways layer shifts partway through — the print is perfect below a line and offset above it
Loose pulley grub screws or incorrect belt tension letting the X or Y axis lose position mid-print
Mechanical & Motion 2026-06-14 - Makita HR2470
SDS drill still spins normally but has stopped hammering, or hammers weakly with a change in sound
Worn or hardened O-rings in the pneumatic hammer mechanism (or dried-out grease) letting the air cushion leak away
