Cutting telescope mirror blanks out of a thick glass tabletop

In this video I cut seven telescope mirror blanks of various different diameters out of a thick glass tabletop. I used my Makita glass saw to cut wedges out of the round tabletop, then turned the wedge shaped pieces round on my Rigid wet saw. please visit mdpub.com/scopeworks/ for more information.

Ensure you enable subtitles (click on "CC" bottom-right) to help where the sound is not audible. Modern optical telescope use mirrors and very few lenses. Unlike bathroom mirrors, where the shiny layer is sealed in to the back of the glass, telescopes use so-called “first surface” mirrors, with the reflective layer on top. This makes them difficult to clean. When they get dirty or as they loose reflectivity over time, they need to be re-aluminised. Professional telescopes in constant use, need their mirrors to be re-aluminised roughly every two years. The word “aluminising” suggests that aluminium is involved – which is indeed the case. …

Presented by Johann Swanepoel at the ASSA Symposium, 2012 October 13, at SAAO in Cape Town. "The purpose of the presentation will be to share my experiences and knowledge gained in the making of two 20-inch f/4.3 telescope mirrors. It will cover details of a versatile machine that was built for the grinding, polishing and figuring of the mirrors. It will further include details of the various full and sub-diameter tools that were made and used. An explanation will be presented on the optical testing methods used throughout the figuring process, including an improved application of the Foucault test and the corresponding digital data…
