condition:
excellent
QR Code Link to This Post
Complete top-slide screwcutting feed unit with:
Gearbox / feed housing
Universal joint drive shaft
Engagement / adjustment controls
This is the original Lorch system that mechanically links spindle rotation to the top slide, allowing precise automatic feed and thread cutting without a full leadscrew setup.
Hard to find complete with the drive shaft — many sets are missing components.
Compatibility:
Designed for the Lorch 65 mm center height series (LLRGN and LAS)
Condition:
Fully functional
Smooth mechanical movement
Normal cosmetic wear consistent with age (see photos)
Ideal for:
Lorch LLRGN / Lorch watchmaker lathe setups
Restoration projects
Collectors of precision German tooling
I also have the matching lathe and cross slide available separately.
Provenance:
This tool comes from the lifelong estate of a master restorer of clocks, musical instruments, and complex automata (including Violano Virtuosos). Every accessory was purchased new in 1952 and used for ultra-high-precision restoration work.
