Our intent is to provide a source for lower cost, mirror blanks, and supplies for grinding your own telescope mirror. If I had known as a kid how, well not easy, but indeed not as hard as I would have expected to grind my own mirror. I sure would have had a much nicer scope then. At present we have a supply of high quality Pyrex mirror blanks.
Jan 05, 2017· I tried the short gear from the kit and the grinding problem went away but I then had the mid rotate stall problem. I tried the new motor with worm and that didn't change anything. I finally called it quits due to diminishing interest levels. (I've probably had the mirror …

For hand grinding, the coarse grit sequence of 40, 60, 80, 120, 220 is typical (start at the grit size appropriate for your mirror diameter as given in the section above). Silicon Carbide is used almost exclusively. Fine grit sequences vary more, and are often adjusted based on the supplies at hand.

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.

Step 6: Measure the Sagitta. Continue grinding until you get the desired curvature. To estimate the curvature, we will use a dial indicator to measure the sagitta. If you want to build a telescope for planets and moon observation, you will need a longer focal ratio (F/8 or higher). This means a shallow mirror.
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.
