The 1.3m telescope mirror blank has been completed by Peter Wangsness and is now at JP Astrocraft in Charleston, 1.3-m Mirror Grinding Machine Mirror-O-Matic – Dr. Debug Grinding your own telescope mirror seemed like a cool idea until I did research and discovered all the physical.
Mirror Grinding Machine. telescope mirror grinding machine based on Dennis Rech's M-o-M 20. . SkyBadger - Mirror Grinding Machine. I have a Mirror-o-maticmirror making machine that I swapped with MikeMS for a Newtonian telescope that was no use to me. The grinding machine had been built to the design of the mirror-o-matic design of.
Nov 06, 2020 telescope mirror grinding machines - MC World. 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.
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 telescope mirrors starting with a 24-inch and then a 60-inch mirror for a telescope initially intended for the Yerkes Observatory.

Mirrors can only be made with Special Precision Equipment in Expensive Factories or Labs Not True! Telescope mirrors can be made in your kitchen, basement or garage with nothing than the mirror blank and a second piece of glass (called the tool) to rub the mirror.

Thin Telescope Mirrors . Abridged from an article appearing in Telescope Making 12 Provided Courtesy of Astronomy Magazine Article's Author Bob Kestner . Part I - Grinding . For many years, amateur astronomers and telescope makers thought it essential that glass for telescope primary mirrors be at least one-sixth as thick as its diameter.
10 Inch Mirror Blanks, 3 4 Thick $55 + S H (16) Shipping prices are to the USA - not shipping outside the US, sorryCombined shipping is possible - Write. For a complete mirror making KIT, with all abrasives, polishing compounds, pitch, and grinding tool included, please see our Buy Telescope Mirror Kits website for great prices on plate glass.
Grinding telescope reflectors of 15-inch diameter and over makes it necessary to employ a motor-driven turntable. Small mirrors are generally ground and polished by rotating the tool, fastened to the turntable, and working the mirror blank by hand either in straight or in circular strokes over the tool. In this case the overhang of the mirror.
Stone tools go back 3.3 million years. Pounding, scraping, knapping, grinding combined with fire, heat, melting leads us today to grinding telescope mirrors from glass. Making a telescope mirror is one of the most satisfying and sublime joys you will experience. It's also arguably the most accurate surface made by man or machine. If the mirror.
Strasbaugh polishing and grinding machine. You wont find very many of these around. Strasbaugh is the premier manufacture of machines used by the professionals. This machine is solid no plastic or wood. You can adjust the spindle and eccentric speed with a turn of a knob while running. It makes mirror grinding a pure joy.
Gordon Waite sets up his fixed-post mirror grinding machine to begin rough grinding on an 11 f 4.3 telescope mirror. He uses a grinding tool made from dental plaster and steel pieces to speed up grinding. Gordon shows the setup for spin grinding at high speeds and with added weights to get the job done as fast as possible.
Nov 01, 2011 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.
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 glass 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 glass like Pyrex has no practical (visible at.
Oct 15, 2012 Page 1 of 2 - Making my own fixed post mirror grinding polishing machine - posted in ATM, Optics and DIY Forum Hey guys. Im thinking of making my own fixed post mirror grinding polishing and curve generating machine. Ive got loads of questions regarding the design so Ill just start firing away Do I need an eccentric moving tool to be able to polish a mirror spherical.
Sep 28, 2002 Grinding an 8″ F 10 Telescope Mirror. For this project (my first time ever grinding a mirror) I ordered an 8″ Black Vitrified Ceramic (BVC) blank without a pregenerated curve from ASM Products in Ste-Basile PQ. Ordering from Canada is always cheaper once you factor in all the taxes – all told the kit cost about $185.
Jul 27, 2021 Making a telescope mirror. To start, a new mirror blank is “sanded” down to create a precise parabolic curve in a process called grinding. To do that, the blank is.
Diamond generator for hogging out mirrors - the blue is the angled cutter Primary Mirror. The primary mirror at f 3 required a lot of glass to be removed to reach the correct depth. Even with a grinding machine this is laborious to say the least. To get over this problem Brian built a diamond generator. This can hog out deep mirrors in half an.
You could try Advanced Telescope Making Techniques by MacIntosh. There are several grinding machines plans given as examples. I too would recommend the making of a couple of smaller mirrors to get the feel of how things blend when using a machine. I used to remove the arm from my machine and finish off the polishing by hand on the rotating.
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 glass should have a look at the MOM web site and plans. There are lots of good ideas there. The large wood circle will become the base of the turntable.
Want to about Newtonian telescopes the internet is replete with information about all types of telescopes. Typically, the primary mirror is made of glass. Pyrex is commonly used for the primary mirror because of its thermal stability, but for small mirrors, plate glass will work fine too. Telescope mirrors are relatively thick.
