Brass Telescope

Replenishing a 100-year-old brass microscope for OMiD museum. Various cylindrical steel blocks were mounted on a lathe chuck, and inserted inside each tubing. With the aid of a soft hammer, the original smooth tubular finish of the telescope was preserved. Each tube was polished by Scotch-Brite, the machinists’ magic way of bringing shine out of any metal. The uncemented doublet was fun to disassemble, and see the early years of telescope making technology. The eyepiece has the nice swing in shutter to keep out the dust. Nice old semicircular knurl around the front objective, and eyepiece barrel.
