My Mirror Grinding Machine. For a long time I've wanted to build a machine for grinding telescope mirrors. Dennis Rech's M-o-M designs finally inspired me to just get up and do it. Over the years, I'd been collecting motors, gear boxes, pulleys, etc. Most of them came from industrial junk yards. To use these parts, I had to modify some of Dennis' plans. How I did it is described below. This ...

Mirror Grinding Machine Leonardo’s Mirror Grinding Machine. leonardo miror grinding machine. The mirror or lens grinding machine is a masterpiece of mechanical engineering. It has several gears in mesh at all times and also has several variable settings built into it. This machine was most likely designed by Leonardo while he was either investigating the different ways that light reflected ...
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 Telescope Making" Book 1. A bowl which rotated was fitted to the spindle. I also built another machine of the same type. Also a Hindle type machine for a southern firm to grind and polish 12.5" mirrors ...
I borrowed a few ideas from the Mirror-O-Matic mirror grinding machine, particularly how to mount the turntable on top of the pulley. Anyone building machinery for cold-working should have a look at the MOM web site and plans. There are lots of good ideas there.

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 beneficial for the hands of a musician. I started to look around and quickly found Dennis Rech's website about the M-o-M (Mirror – o – Matic) that he developed ...
Mirror grinding machine construction log I started thinking about building my own mirror grinding machine several years ago. Having been on the ATM list now since almost the beginning of it here on the web, I had lots of of inspiration reading of others projects and viewing their webpages I started out with en table and some bits cobbled out of our scrap bin at work, I didn't get to far ...

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. Telescope making is at the heart of the Springfield Telescope Makers - after all it is two thirds ...
Fixed-post machine grinding is where the mirror is on a turntable rotating around 20 PRM [speeds vary], and a 75% tool is on top. They are already curve-generated. The tool is hanging over the mirror by 1/6 the diameter of the tool, or about 1/8 diameter of the mirror, and is fixed in this position. The motor turns the mirror and the differential rotation enables the grit and water to grind ...
Grinding Machine for Large Telescope Mirrors. I designed and built a grinding machine for mirrors up to 42 inches [1.1m] in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work. The machine can also work smaller mirrors if the drip pan is moved to the fast shaft on the side of the machine. I shared a Sketchup model ...
Indeed, between 1513 and 1517, he imagined machines to grind and polish telescope mirrors, which, at the time, were made of bronze. Unfortunately, it seems that, during his life, Leonardo da Vinci didn't actually build his invention, as he often did with other inventions. Model of the machine imagined by Leonardo da Vinci to grind mirrors . Model of the machine imagined by Leonardo da Vinci to ...

The mirror (or tool) was then carefully placed on top of the tool (or mirror) and grinding started (i.e., pushing the disk on top back and forth). The procedure was quite similar to grinding a smaller mirror, except that the disks are heavier. With the coarser grits, pressure was applied to speed grinding. At the start of grinding, each wet lasted a few minutes before the disks needed a ...

The grinding machine was moved to Pasadena in 1904 to complete work on the 60-inch mirror. At some later time the apparatus was transferred to the California Institute of Technology. The Institute then sold the machine to the Lick Observatory of the University of California in 1949. The machine was used for making numerous mirrors over the next four decades and extensively modified over that ...
2006-09-26 Grinding and polishing your own mirrors is a long, arduous process. Instead of lapping the blank by hand, Laurie Hall built this mirror grinding machine from scratch.
2011-11-01 Basically there are two types of grinding/polishing machine. The ‘traditional’ type which involves the mirror rotating at a relatively slow speed, a few rpm for a big mirror (16-20 inches) with the tool moving across the mirror, from side to side, at a higher rpm depending on the size of the mirror and/or tool. This is the method that I use; one of my machines is shown in the first ...
The grinding machine had been built to the design of the mirror-o-matic design of Dennis Rech ( link ). While the bulk of the components were in place it wasn't finished: some linkages were not in place, the tool drive arm was unfinished and a few other bits weren't there. However the big stuff was in place and well made. I finished off the machine, building parts and providing linkages from ...
Making A Mirror Grinding Tool By Allen Malsburry The average person would never think, “I can make my own telescope.” Most amateur astronomers believe, “I can buy a better telescope than I can build.” Neither is actually correct. For many decades now, amateur astronomers have been building their own telescopes. In the good old days, building your own telescope was the only way to get ...
In September 1858, shortly after his return from Europe, Draper began the construction of a mirror grinding machine of Lord Rosse’s design. Advances in Abrasive Technology XVI The superhard grinding wheel with large-grit size plays an important role in precision mirror grinding
A good starter size is the 150 mm (6") mirror. A 200mm (8") will also work. Most ATM books and websites recommend a Pyrex® mirror blank, but in my opinion, annealed plate is better for this first, "learn and practice" mirror.It is cheaper, it is softer and grinds faster, needing less abrasives and with these small sizes, the low expansion like Pyrex has no practical (visible at ...

2015-03-16 Page 1 of 5 - Making a Mirror grinding Polishing machine - posted in ATM, Optics and DIY Forum: Hello, I am on the half of the way to make a mirror grinding machine inspired by original M-O-M design. I made the pulley arrangement such a way that, both the turn table eccentric spins at 50 RPM fixed. I wont go for making mirror bigger that 10.5 (or max 12).

The Joy of Mirror Making Mel Bartels Rough Grinding The first milestone is putting a curve into the mirror face. The curve's depth dictates the mirror's focal length. The curve should be spherical. Creating the curve can be done by several methods: The curve is ground into the mirror face using a grinding tool. The curve is pre-generated for you. The curve is created by slumping the blank in a ...
The Joy of Mirror Making Mel Bartels Polishing Polishing a mirror is one of the great joys you will experience as a maker and builder. It's also arguably the most accurate surface made by man or machine. If the mirror is expanded to the size of a football field, then the mirror’s surface will be smooth to 1/1000 inch or 1/30 millimeter! Polishing a 10.5 inch [27cm] F/2.7 plate meniscus ...
