Which Style Grinding Machine For Telescope Mirror? (Best solution)

What is the most efficient method of grinding mirrors?

  • Roughness in stroke numbers, tool rotation, and disc rotation are all important factors in good mirror grinding. Making a tile tool out of tiles that have been broken with a hammer can help to increase the unpredictability of the game:) Always work with water on your hands! Prior to beginning to grind, sprinkle some water on the grit.

How do you grind glass for a telescope?

The most common question I receive is, “How do you construct a telescope mirror?” My typical response is, “You take two rings of glass and rub them together for a long period with fine-grained sandpaper in between.” That’s exactly what you’ll be doing. For a short period of time. Increasingly deepens the curve in the mirror while the tool is on top (often abbreviated TOT).

How thick should a telescope mirror be?

Telescope Mirrors That Are Too Thin Long ago, amateur astronomers and telescope manufacturers believed it was vital that the glass used in telescope main mirrors have at least a sixth the thickness of the mirror’s total circumference.

How do you find the center of a telescope mirror?

Make a small hole there, about 1/10-inch in diameter. Another option is to measure the diameter of your mirror and draw a circle on a blank sheet of paper using a compass (with the needle set to 12 times the mirror’s diameter). The center of the circle will be defined by the pinprick of the compass point on the paper.

How do you polish a mirror on a telescope?

Place the mirror face-up on a towel and, with the drain open, spray the mirror’s surface with room-temperature water for a few minutes to remove any lingering residue. The majority of dust and grit will be securely removed in this manner. For removing grit from a telescope mirror, the most safest method is to blast the surface with tap water, as seen from left to right.

What type of telescope is a Dobsonian?

A Dobsonian telescope (which utilizes a mirror rather than a lens) is similar in design to a Newtonian telescope in that it is a reflecting telescope (concave collecting mirror is at the rear of the telescope tube, eyepiece is on the side of tube, up near the front).

Do telescope mirrors warp?

FABRICATION OF THIN MIRRORS FOR TELESCOPES THAT REFLECT Written by HAROLD C. The result will be warping due to the fact that “it will bend with its own weight,” as the phrase goes in the industry. The notion that thin mirrors warp as a result of their own weight is irrational on its face, even if it is true that thin mirrors are discovered to warp.

What does the primary mirror do on a telescope?

FABRICATION OF THIN MIRRORS FOR TELESCOPES THAT REFLECT LIGHT With contributions by HAROLD C. The result will be warping as a result of the fact that “it will bow under the weight of itself.” The notion that thin mirrors warp as a result of their own weight is irrational on its face, even if it is true that thin mirrors are observed to do so.

Why telescope mirrors are thick?

Essentially, it is necessary to avoid warping, but there is a limit to how thick it may be. As a result, the thicker it is, the longer it takes to cool to the temperature of the outside air! In order to be able to be held securely in a narrower scope, amateur telescope mirrors are thicker per inch than huge professional telescope mirrors!
