The mirror machine came to me as a result of astronomical horse-trading, swapping a large GEM mount and a 8" Newtonian OTA for the machine as it was and a start kit consisting of two 6" blanks and the grit, rouge and pitch to manufacture a mirror. The grinding machine had been built to the design of the mirror-o-matic design of Dennis …

Newtonian telpe is its primary mirror. Most Newtonian primary mirrors have either a spherical or a parabolic shaped concave face. Unlike most other mirrors in your home, the mirror coating of a Newtonian mirror is actually applied to the front face of the glass, not the back. The light collected by the Newtonian primary mirror does

One machine is designed for grinding concave mirrors of small focal length. The other machine, a much larger piece to implement, grinds mirrors of large focal lengths. Though Leonardo da Vinci creates sketches of mirror grinding, one crucial and logical question to ask is whether he used such mirrors in his artwork or drawing.
I eventually decided I needed to build a dedicated edge grinding machine. This is how I did it. I started the build by making a sturdy frame for the unit out of 2x4 lumber and 3/4 inch thick plywood. Wheels were added to the bottom of the unit so it can be wheeled outside. The grinding operation will be messy, so it will need to be done outside.
I use large steel pulleys (like from cranes, scrapyard recycle items) with tables made from Corian (countertop) layers. Rigid, stable, waterproof. I've also got a large thick machined alum disc that will go as …
Mirror-O-Matic grinding machine. When I decided in 2009 after a ten-year break to get into mirror making again, it quickly became clear to me that I would need to construct machine, as hand grinding big mirrors is not something very …

Much is also unchanged - mirror grinding techniques are very similar to those written up by Porter and Ingalls in the 20´s and 30´s. Many amateur astronomers still choose to fabricate their own instruments, for the pride of accomplishment, the gaining of knowledge and the insurance of quality.
I assume you are talking about a telpe mirror. I have read a lot and ground one small mirror some years ago but did it all by hand. If I remember properly, some of the features you want in a grinding machine are the ability to change the stroke's length as well as the path it takes across the surface (radial, cordial).
The time it takes to grind and polish a concave mirror using a grinding/polishing machine can vary depending on the size and complexity of the mirror and the precision required. However, it is not uncommon for the process to take several days or even weeks to achieve a high-quality finish. This is because the grinding and …
Grinding and Polishing the Mirror. Once you've appropriately set up your workspace, one of the most critical steps in DIY telpe mirror crafting is grinding and polishing the mirror. This process involves removing material from the mirror's surface to achieve the desired curvature, and subsequently achieving a smooth finish for the ...
Fig. 3 shows the envelope grinding along with tool posture angle θ and envelope trace height h e.On the parallel YZ-sections, the CL and the angle ϕ are driven by the linkage of Y-axis and Z-axis translations and A-axis rotation according to (1), (2), (4), (5).The tool path interval f x is driven by the differential translation of X-axis. The …
George Willis Ritchey built this mirror grinding machine at the Yerkes Observatory in Williams Bay, Wisconsin, in the late 1890s. Under the sponsorship of George Ellery Hale, the machine was used to grind a series of telpe mirrors starting with a 60-inch mirror for a telpe initially intended for the Yerkes Observatory.
