: Rotate the telescope so it is horizontal. Many Hilger & Watts models have a short telescope designed to swivel completely; ensure it is positioned to match the cutouts in the case. Close Accessories

: Fold in any external mirrors used for circle illumination. Retract the ray shade if it was extended. Loose Clamps

: Slightly loosen the horizontal and vertical clamps before placing it in the case, then gently tighten them once the instrument is seated to prevent movement during transport. Mounting to the Case Base Most Hilger & Watts theodolites sit on a base plate within the container. Lift the instrument by the (the base frame) rather than the telescope.

Align the footscrews with the specific indentations on the case's bottom half.

Secure the instrument to the base plate using the integrated fixing screw or locking hooks. Store Small Accessories Check for dedicated slots in the case for the (plumb bob) and any battery-powered lamps or tools.

The metal cylinder in the corner of many original cases is designed specifically to hold the plumb bob weight and string. Seal the Case Lower the top half (hood) of the case over the instrument.

Engage the metal buckles or latches. If your case has the original leather strap

To "repack" a Hilger & Watts theodolite effectively, you must follow a specific sequence to ensure this 9-pound precision instrument is secured without damaging its delicate glass scales or internal micrometer drums. 1. Preparation for Storage

Cleaning: Before packing, use cotton wool or a small brush to remove dust from the surface. If the instrument was exposed to rain, ensure it is completely dry. Clean the exposed optics only with high-absorbent cotton or lens-cleaning paper; never use handkerchiefs or clothes.

Battery Removal: If your model is electronic (like the Microptic Universal Auto-collimator), always turn off the power before removing the battery to prevent potential damage. 2. Positioning the Telescope

The "Transit" Position: Rotate the telescope about its horizontal axis until it is in a compact state. For many Hilger & Watts transit models, the telescope is short enough to swivel completely.

Alignment: 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

Check the Fit: Most Hilger & Watts cases use a specific internal geometry or custom-made foam inserts to support heavy components and relieve pressure on sensitive areas.

Matching Marks: When lowering the instrument, align the base (tribrach) according to any internal markings. For example, some models require aligning a convex mark on the instrument with a concave mark on the base.

Security: Once seated, the instrument should not "wiggle." If your case uses string or straps, ensure they are secured to prevent shifting that could spoil the paint finish or misalign the optics. 4. Final Transport Precautions

Vertical Orientation: If you are carrying the instrument while it is still attached to a tripod, always carry it vertically over your shoulder, never horizontally.

Shock Protection: For long-distance transport, ensure the external case is shock-proof. Avoid leaving the cased instrument in extreme heat (like a car trunk) for long periods, as it can adversely affect performance.

Repacking a vintage Hilger & Watts theodolite is a meticulous process focused on restoring smooth mechanical movement by removing aged, hardened grease and applying fresh lubricants. 1. Scope & Preparation

Objective: To restore the horizontal and vertical circles, tangent screws, and leveling footscrews to a "stiction-free" state.

Tools Required: Fine-point screwdrivers, a dusting bulb (avoid canned air), Q-tips, and isopropyl alcohol.

Lubricant Choice: Use a high-quality, temperature-stable grease (e.g., synthetic instrument grease). 2. Disassembly & Cleaning

External Lenses: Always clean the outer lenses first to avoid scratching them during mechanical work. Use a single-swipe technique with alcohol-dampened swabs.

Component Removal: Carefully extract the tangent screws (E1, E2) and the leveling footscrews.

Degreasing: Soak metal mechanical parts in a solvent to remove "crusty dust" and old grease. Do not submerge parts containing optical glass or etched scales, as high temperatures or strong chemicals can weaken the cement holding them in place. 3. The Repacking Process

Application: Apply a thin, even layer of grease to the threads of the screws and the bearings for the telescope (C).

Distribution: After reassembly, rotate the alidade (the upper rotating part) slowly in both directions to evenly redistribute the new grease across the horizontal circle.

Tensioning: When re-attaching the tripod adapter or base components, tighten screws evenly and slowly (e.g., 1/2 turn at a time) to prevent binding. 4. Post-Repack Calibration

Leveling: Mount the theodolite on a stable tripod and use the footscrews to center the bubble.

Index Error Check: Verify the vertical circle orientation. If the index error persists, take measurements on different parts of the circle and use the mean of the readings.

Focusing: Adjust the eyepiece to eliminate parallax and ensure target wires are sharp against the crosshairs.

The rain in the Cascades didn’t just fall; it reclaimed things. For Elias, a retired surveyor, it meant it was finally time to tuck away his most faithful partner: the Hilger & Watts Microptic No. 1 Theodolite.

He cleared the mahogany workbench, the scent of old machine oil and cedar filling the shed. The instrument sat there, a masterpiece of mid-century British engineering, its forest-green enamel worn silver at the adjustment knobs. "One last tuck-in," Elias murmured.

The repack was a ritual of precision. He began by locking the horizontal and vertical circles, ensuring the glass scales wouldn't jar during storage. He cleaned the leveling base—the tribrach—until the three leveling screws turned with buttery smoothness. Next came the internal optics; he checked that the micrometers were set to zero, preventing tension on the delicate internal springs.

Then came the "coffin"—the heavy, fitted steel carrying case. Elias checked the internal gaskets, ensuring the rubber seal was still supple enough to keep out the mountain damp. He lowered the theodolite onto its mounting plate. It clicked into place with a definitive, metallic thump that sounded like a closing chapter.

He tucked a fresh packet of silica gel into the corner and snapped the heavy brass latches shut. The Hilger & Watts was home, preserved in its steel shell, waiting for the day another set of eyes would need to find a true line through the mist.

Additional Tips

"Repacking" a Hilger & Watts theodolite typically refers to the process of stripping down the mechanical assemblies, removing old, hardened grease (a common issue with vintage instruments), and applying fresh lubricants to ensure smooth operation of the horizontal and vertical axes. Understanding Hilger & Watts Mechanics

Hilger & Watts instruments, particularly the popular Microptic No. 1 and No. 2 series, are renowned for their precision glass scales and optical reading systems. Unlike modern digital units, these rely on highly polished metal-on-metal bearings that must be free of debris to maintain accuracy. General "Repack" Workflow

While specific factory service manuals are rare for the public, the general procedure for repacking a vintage theodolite involves several critical steps:

Disassembly: Carefully removing the telescope from the trunnion axis and separating the upper plate from the lower limb.

Degreasing: Using a safe solvent (historically dry-cleaning solvents or mineral spirits) to remove old, gummed-up grease from the spindles and tangent screws.

Inspection: Checking for "scoring" on the bearings or damage to the optical glass circles.

Lubrication: Applying a high-quality, non-migrating synthetic grease. Caution: Excess oil can migrate to the optical glass scales, causing them to cloud or "fog".

Reassembly and Adjustment: Ensuring all axes are perpendicular and the plate levels are calibrated after re-seating the bearings. Key Resources for Manuals

Repacking a vintage Hilger & Watts theodolite is a critical maintenance task for restorers and surveyors using legacy equipment. These precision instruments, known for their Microptic transit designs and high-quality optics, often suffer from "frozen" or stiff movements due to the degradation of original lubricants over several decades. Understanding Hilger & Watts Mechanics

Hilger & Watts instruments, such as the Mark B and Microptic series, utilize a closed-frame design with internal graduated circles. Key mechanical components that typically require repacking include:

Tangent Screws: Fine-adjustment screws for elevation and horizontal movement.

Vertical and Horizontal Axes: The main spindles that allow the telescope to transit or rotate.

Levelling Foot Screws: The three screws at the base used for precise leveling. Essential Tools and Materials To perform a manual repack, you will need:

Solvent: Gasoline or specialized degreasers for removing old, hardened grease.

Lubricant: High-quality instrument grease (modern synthetic watch or instrument greases are preferred over original organic ones).

Tools: Small precision screwdrivers and possibly a capstan head screw adjuster. Cleaning Supplies: Soft lint-free cloths and brushes. Step-by-Step Repacking Procedure 1. Disassembly of Tangent Screws

Begin with the most accessible parts. According to maintenance guides for similar vintage models, you should: Unscrew the set screws and brake handwheels. Remove the spacing rings and stationary bushings.

Carefully withdraw the micro screw rod. Caution: Ensure the nylon or white pads on the locking levers are not lost during this process. 2. Degreasing and Cleaning

Wash: Submerge mechanical metal parts in solvent to dissolve "petrified" grease.

Brush: Use a soft brush to ensure threads are completely clear of debris.

Dry: Allow all parts to air dry completely or use low-pressure compressed air. 3. Lubrication and Reassembly

Apply a thin, even layer of new grease to the threads and bearing surfaces. Avoid over-lubricating, as excess grease can attract dust or migrate into optical paths.

Reinstall the screw rods, bushings, and handwheels in reverse order of removal. 4. Spindle and Axis Maintenance

For the main vertical and horizontal axes, the process involves removing the telescope from its bearings. Clean the spindle and the sleeve thoroughly.

Apply a very light film of oil or specialized thin grease. These axes require extremely smooth, friction-free movement to maintain accuracy. Post-Maintenance Calibration

Once repacked, the instrument must be recalibrated to ensure accuracy. Critical tests include:

Vertical Arc Test: Ensures the vertical circle reads zero when the telescope is perfectly horizontal.

Leveling Check: Verify that the bulls-eye level and plate levels remain centered through a 360-degree rotation.

Angular Accuracy: If readings differ by more than 10 seconds after rotation, further adjustment of the vertical axis may be required.

For detailed diagrams and model-specific instructions, enthusiasts often look for vintage publications like the Watts 1950 Instruction Booklet or the 1963 Operations and Maintenance Manual. Microptic transit theodolite, 1954
