Restoring a vintage Hilger & Watts Microptic Theodolite is a rewarding project for any surveying enthusiast, but "repacking"—the process of cleaning out decades-old, solidified grease and applying fresh lubricant—requires a delicate touch to avoid damaging the precision glass circles. 1. Pre-Service Checklist
Before starting, ensure you have a clean, lint-free workspace. Essential Tools
: Small precision screwdrivers, a high-quality degreaser (like naphtha or isopropyl alcohol), and lint-free swabs. Lubricants
: Use a high-quality, synthetic instrument grease. Avoid heavy automotive greases; modern equivalents like AeroShell 7
or specific optical greases are often recommended for their stability and low outgassing. Documentation
: If you lack the original physical manual, digital reprints are occasionally available through specialized archives like VintageMachinery.org 2. Disassembly & Cleaning
The goal of a "repack" is to address the moving parts without disturbing the optical alignment. External Cleaning
: Begin by removing dust with a soft brush. For the body, a damp cloth is usually sufficient. Removing the Vertical & Horizontal Drives
: Loosen the tangent and clamp screws carefully. In many Hilger & Watts models, the tangent screws can be backed out to reveal the internal springs and threaded rods. The "Old Grease" Problem
: Over 50+ years, original lubricants often turn into a wax-like substance. Use a degreaser to fully dissolve this. hilger watts theodolite manual repack
: Keep all solvents away from the glass circles and etched scales, as they can sometimes damage the delicate coatings or adhesives. 3. Repacking the Bearings Application
: Apply fresh grease sparingly. A common mistake is over-lubricating, which can attract dust or migrate onto the optics. Smoothness Check
: Reassemble the drive components and rotate them through their full range. The movement should be "silky" and consistent without any gritty feedback. 4. Final Adjustments
Once repacked, you must check the instrument's basic calibration: Plate Level
: Ensure the bubble remains centered when the instrument is rotated 180 degrees. Optical Plummet
: Verify the plummet still points to the same ground mark when the instrument is rotated. Transit Check : Ensure the telescope transits smoothly at both ends.

Repacking a vintage Hilger & Watts theodolite (like the popular No. 2 Microptic
models) requires careful alignment to ensure the instrument fits into its custom-fitted steel or metal case without damaging the delicate optics or glass circles. www.mathsinstruments.me.uk Repacking Instructions Prepare the Instrument Level the Telescope
: 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 Try these in Google or DuckDuckGo
: 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
, ensure it is threaded correctly through the buckles to provide extra security for the lid. ANTIGUEDADES.ES Summary of Parts and Materials
: Rectangular with a rounded/domed top, often painted greyish-green with a leather carrying strap.
: The instrument itself is typically a mix of steel, brass, and plastic with finely engraved glass circles. Dimensions
: A standard storing case is approximately 11.8 inches (30 cm) high and 8.26 inches (21 cm) wide. ANTIGUEDADES.ES Hilger & Watts Microptic manual for more technical maintenance? Antique Theodolite Hilger & Watts, 1968 - ANTIGUEDADES.ES
Searching for a specific blog post titled "Hilger Watts Theodolite Manual Repack" or something similar reveals a fascination among vintage instrument enthusiasts for the meticulous care these precision tools require. While "repacking" often refers to the careful storage or disassembly for cleaning, many enthusiasts focus on the mechanical restoration of these iconic British instruments. The Appeal of the Hilger & Watts Theodolite
Hilger & Watts was renowned for its high-quality optical and scientific instruments. Their theodolites, like the Microptic No. 1 Microptic No. 2 If you tell me the exact model of
, were workhorses of surveying from the mid-20th century. A "repack" in this context usually involves: Lubrication:
Replacing dried-out grease in the horizontal and vertical axes. Optical Cleaning:
Gently clearing fungus or haze from the complex internal glass circles and prisms. Collimation:
Ensuring the line of sight is perfectly aligned with the mechanical axes. Resources and Guides
If you are looking for a manual or restoration tips, these resources are excellent starting points: Virtual Archive for Surveying: Sites like Land Surveying History often host scanned PDF versions of original Hilger & Watts manuals Restoration Communities: Forums like The Surveying Forum or specialized groups on platforms like
often feature detailed threads (which can read like blog posts) where members share step-by-step photos of "repacking" their instruments. Operational Basics: For those new to manual theodolites, Engineer Supply Johnson Level provide comprehensive guides on setup and use. Restoration Tips for the "Repack" Avoid Harsh Solvents:
Use only mild cleaners like isopropyl alcohol for metal parts and dedicated optical cleaners for glass. Mark Your Parts:
When disassembling a Hilger & Watts, use a scribe or marker to ensure everything goes back in the exact same orientation. Small Sight Adjustments: Don't forget to check the plate level and horizontal axis once you've finished the internal work. step-by-step guide
