Description
Product Overview
This vintage Swiss lever-operated rotary table is a compact, purposeful fixture for milling accurate arcs, radii, and blended profiles on a precision mill or jig borer. At 100mm in diameter and operated by a removable steel handle, it lets you sweep work through a repeatable arc between two adjustable screw stops — no worm gear, no fuss, just clean, consistent geometry every time the lever reaches the stop. Believed to be a Hauser accessory from the golden era of Swiss precision tooling, it’s a rare find for anyone doing exacting small-part work.
- Lever operation with adjustable screw stops — A dedicated stop block clamps to the base rim and carries two knurled screws that set the exact start and end of the swing. Once dialled in, every arc is identical without re-measuring, which matters when you’re blending a radius into a shoulder or milling a series of matching profiles in a production run.
- 100mm round table with four radial T-slots and centre bore — The four radial slots allow direct workholding or sub-fixture mounting, and one slot extends into the arm so work can be set deliberately off-centre for offset arc work. The centre bore provides a datum reference for concentric setups. This is far more flexible than a simple faceplate.
- Degree scale graduated 0–90° each way — The rim is marked in single-degree increments in both directions from zero, giving you a clear visual reference for setting stop positions and verifying your arc angle before cutting. Not a precision angular measuring instrument on its own, but a practical guide for setting up the stops accurately.
- Compact, low-profile format — approx. 270mm overall length including handle — Designed to sit under the spindle of a jig borer or small precision mill without consuming the full Z-axis travel that a full worm-driven rotary table would. The handle is removable, keeping the footprint minimal when the unit is mounted and clamped.
- Ideal for — milling arcs and radii on jig-bored components, blending corners on die and mould work, producing repeated identical profiles on small precision parts, fixture-plate work on a toolroom mill, and model engineering projects requiring accurate circular interpolation without CNC.
Condition
Used (Good Condition / Vintage Workshop Patina)
The table is in honest used condition consistent with a quality Swiss tool that has seen careful workshop service over several decades. The pivot action and lever swing are smooth, and the stop block and knurled adjustment screws function as intended — the stops engage positively and hold their set position. The table face shows surface marking and wear consistent with age and normal use; this is cosmetic patina, not damage to the working reference surfaces. The degree scale on the rim is clear and fully readable. The steel handle is present and sits firmly in its socket. The base locating features — centre bore, tapped mounting holes, and locating insert — appear intact and serviceable.
Honest disclosures: the table face carries some marking that is typical of a tool that has had work clamped directly to it; buyers intending to use the face as a finished reference surface should assess this in person or from the photographs. Some general age-related discolouration and light surface oxidation is present across the body — this is surface-level only and does not affect function. Important note: the seller has not been able to fully verify pivot play or confirm that all tapped holes are clean and undamaged prior to listing — buyers should inspect these points on receipt and chase threads if required before mounting. For precision arc work, verify your stop-to-stop repeatability with a dial indicator across several cycles before committing to a production run.
Included:
- 1 x Swiss lever-operated rotary table, 100mm diameter, with adjustable screw stop block (believed Hauser, c.1950s–1970s)
- 1 x Removable steel handle
- 1 x Adjustable stop block with two knurled screws
Not included: Original case or storage box (not present), mounting hardware (T-bolts, clamps, or sub-plates for mill table mounting), documentation or original manufacturer literature.
Brand Information
This table carries no maker’s name — standard practice for Swiss precision accessories of this era, which were frequently supplied as unmarked accessories alongside branded machines. Based on its construction, proportions, and stop mechanism, it closely matches lever rotary tables produced by Hauser of Biel, Switzerland — a marque held in the same tier as Dixi and SIP within Swiss jig boring and precision milling. Hauser built machine tools and accessories to toolroom-grade standards, and their accessories were engineered to the same tolerances as the machines they accompanied. Even without confirmed badging, the quality of Swiss toolmaking from this period speaks for itself: ground reference surfaces, proper hardened components, and mechanisms built to outlast the careers of the people who used them.
