Hilger Watts Theodolite Manual Repack <SAFE – 2027>

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

• Glass Circle Graduation: Etched directly onto glass for superior longevity and accuracy.
• Optical Micrometers: Allowing readings down to 1 second of arc (or better).
• All-Season Build: Brass and aluminum housings designed for damp British climates.

Application: Apply sparingly. Use a toothpick to place small dots of grease on the bearing surfaces and gear teeth, then rotate the parts to distribute it evenly. 4. Reassembly & Calibration Once repacked, the parts should glide smoothly.

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.
