This is a GotGrit kit I bought more than a year ago and never had the time or the energy to carry through with The kit is similar to the 12-inch Grinding Kit listed on the GotGrit website for 84.65 -- Except It has 30 pounds instead of 15 pounds of Dental Stone and two 12-inch tile kits instead of only one.
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.
May 30, 2014 This is how you make a telescope mirror out of a hunk of glass Use a sand mixture and another piece of glass to grind away the middle of a concave shape. Repeat with finer and finer grit sand. Dave Barosso demonstrates the technique, but to do it yourself, try to visit one of the Telescope Makers Workshop s classes on Friday nights in Oakland.
Dec 15, 2014 B, To grind the mirror, we use relatively coarse grit silicon carbide, which is not toxic at all mixed with ordinary tap water. The water acts as a lubricant and also to keep down the glass dust silica dust causes very serious lung problems if its dry. So we keep it wet. We begin with either 50, 60, or 80 grit, depending on the size of ...

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 F8 or higher. This means a shallow mirror.

Mirror grinding machine construction log ... to grind one myself. I ordered an 8 kit from Willman-Bell but it has sat on the shelf for several years now. The current project really started out as a design exercise for my CAD work, something to hone my skills on. About the same time we scrapped a DoAll lapping machine at work.

Now days it is easer to buy finished mirrors than grinding kits to make them. Still grinding your own mirror is a key skill that makes you a real telescope maker. To grind a telescope mirror by hand you simply attach a glass tool the same size as your mirror blank to the top of a small, strong stand.
Unfortunately, the cost of mirror grinding kits and pyrex blanks has increased significantly in recent years to the point where any savings from making a mirror versus buying one are minimal at best. Yet, the larger the mirror you make the more money you can save when compared to buying a mirror already made. And before buying a kit, surf the ...

For large thin mirrors, say 12 inches 30cm or greater and 1.5 inches 4cm or thinner, the mirror back must be ground flat, or at least regular in shape before beginning fine grinding the mirrors face. Cast a tool specifically for the mirrors back, and grind with 220 grit, inspecting for low unground spots. Grind until they disappear.
Rough Grinding The first milestone is putting a curve into the mirror face. The curves depth dictates the mirrors focal length. The curve should be spherical. Creating the curve can be done by several methods The curve is ground into the mirror face using a grinding tool. The curve is pre-generated for you.
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.
Rough grinding. This step is about making one side of the glass concave. It will give your mirror its overall focal ratio. If you make the centre deep, you will end up with a fast telescope e.g. FD 4 well suited for deep sky observations. On the opposite, a shallow mirror e.g. FD 8 will be performing very well on planets and the moon.
Mar 16, 2015 Page 1 of 5 - Making a Mirror grinding amp Polishing machine - posted in ATM, Optics and DIY Forum Hello, I am on the half of the way to make a mirror grinding machine inspired by original M-O-M design.
