Hilger Watts Theodolite Manual Repack Patched

Medium-heavy damping grease (e.g., Nyogel 774H or standard instrument grease) for the main horizontal and vertical centers to ensure smooth rotation.

Soak the brass leveling screws, tangent threads, and housing blocks in a small container of mineral spirits or 99% IPA.

The theodolite is an optical instrument used to measure horizontal and vertical angles in land surveying, engineering, and construction projects. It is essentially a refined protractor combined with a telescope, allowing the surveyor to fix points on the ground, establish control networks, and lay out building foundations. The Hilger & Watts theodolites came in several distinct configurations: precision microptic models with internal circle illumination for accurate readings, vernier models for general surveying, and specialized mining theodolites for underground work. hilger watts theodolite manual repack

Despite their age, these manuals are not lost to time. The "repack" of information lives on in several places.

Organize your repack as follows:

: Align the telescope with the main body of the instrument. Ensure all clamps (horizontal and vertical) are slightly loosened . Locking them too tightly during transport can lead to "flat spots" or internal damage if the case is jarred. 3. Placing the Instrument in the Case

Are you preparing a specific model, like the or a MK V , for long-term storage or local transport? Medium-heavy damping grease (e

: This is perhaps the most iconic model, known for its compact size and robust construction. The original manual for the No. 1 is extremely detailed, with sections covering:

: Use a soft brush to ensure threads are completely clear of debris. It is essentially a refined protractor combined with

Highly effective for stripping old grease from purely mechanical brass gears and leveled screws.

Locate the protective cover plate over the vertical circle (usually held by three or four small, slotted screws).
