To begin grinding operations a small pan partly filled with #220 or #240 carborundum or Aloxite mixed with water is placed nearby with a one inch paint brush in it to apply the mixture to the surfaces. Apply some to the lens and the grinding tool (the latter being the glass tool or the concave of the flint element).

An Introduction to the Optics Manufacturing Process
Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a), but more often, many lenses with the same radii are mounted on one surface

Document sans nom. A history of polishing machines. As often in sciences and technology, Leonardo da Vinci was a pioneer, creating machines for the production of optical devices. Indeed, between 1513 and 1517, he imagined machines to grind and polish telpe mirrors, which, at the time, were made of bronze.

However, most of the amateur telpe makers (ATMs) who decide to build their own instrument do it because they want to understand the optical phenomenon involved in a reflector. Another surprising advantage is that hand made optics (if guidelines are followed) tend to have a higher surface quality than the mirrors polished by industrial machines.

In the 1970s, he built three reflecting telpes, each of which took eight months to a year of lens grinding by hand. He also built one of the first hang gliders in the area, which he and his sons flew in the Outer Banks. An amateur scientist and inventor, he held a patent for a toy parachute that released from a kite string.

THE CHALLENGE OF GRINDING LENSES FOR SINGLE LENS MICROSCOPES
THE CHALLENGE OF GRINDING LENSES FOR SINGLE LENS MICROSCOPES. By: Alvaro Amaro de Azevedo - (Brazil) 1.) INTRODUCTION. In my previous article (1), I have discussed the optics of ball lenses for single lens microscopes showing that it's possible to obtain surprisingly good images from low budget materials and resources.
Astro-Tel - Mirror grinding machine
MIRROR GRINDING MACHINE. I made my first mirror grinding and polishing machine over thirty years ago. It used the working principle of the machine illustrated at "A" Fig.3, Page 163, "Amateur Telpe Making" Book 1. A bowl which rotated was fitted to the spindle. I also built another machine of the same type.
Working with (machining) glass
Galileo hand ground lenses to about an inch. Amateur lens makers now do spherical lenses to three inches or so and mirrors to ten inches. Past about four inches lens grinding gets much more difficult as the lenses shift from spherical to parabolic in order to correct distortion. Not too many amateurs will attempt a six inch parabolic lens.

Lenses - Engineering and Technology History Wiki
Lenses were produced by grinding them against a metal tool called a " lap," which had been produced using a lathe. Convex lenses required a lap having a portion of a hemispherical cavity. A male form was used for concave lenses. The laps could be made from any metal, since hardness was not a major factor.
Homemade Telpe Making - Google Search
For the lens grinding tools I used the bottoms from two other jars. I did not bother grinding the edges of these tools so that they were nice and smooth. I just ground out all the sharp edges. I then proceeded to grind and polish both sides of the lens as if they were a small mirror. For a polishing tool I used the base and stem from an old ...
