  • Mirror grinding machine

    Thanks guys, I''m really looking forward to this machine''s completion. There''s a dearth of good "glass pushers" out there, and I''d like to join their ranks. James: I''ve done a couple 6" mirrors and 5" mirrors the hard way, and it''s a major pain, literally. Standing, walking around the barrel and pushing add up to major back problems for me.

  • mirror grinding machines.

    Thanks for the video Jim. I had no idea that these machines ran at those speeds. When I built my machine, I didn''t have a computer or any books on building grinding machines so I built one that mimics the stroke a person would do. For instance, my turntable rotates at just one RPM and the stroke eccentric turns at 36 RPM.

  • Mirror grinding machine

    I assume you are talking about a telescope 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). You also want to build a certain amount of slop into

    I built another mirror grinding machine (out of welded angle iron) to work on the mirror, but never used it. In mid-2008 the desire to finish the 12.5 inch mirror hit again

    Father and son converted their garage into an optical shop in the spring of 1948. They built simple pottery-wheel grinding machines and constructed modified Draper polishers out of 2-by-4s and pillow-block bearings.

Telescope mirrors are relatively thick. The concave shaped face is made by repeatedly rubbing the primary glass blank over another blank called the “tool”.
