GOAL: Refine the surface of your mirror to be an optically polished good quality section of parabola. ABRASIVES: Polishing Compund TOOL: Pitch Lap STROKES: Various strokes are used depending on the changes in figure to be made. See subsections for appropriate strokes. TIME: A 6 f/8 or 8 f/6 mirror will typically be figured and tested in 6 to 12 hours or work, depending on mirror size and

There are several grinding machines plans given as examples. I too would recommend the making of a couple of smaller mirrors to get the feel of how things blend when using a machine. I used to remove the arm from my machine and finish off the polishing by hand on the rotating table.

Stellafane ATM:Mirror Making Myths

Making a Mirror takes Hundreds of Hours of Work. Not True! A 6 or 8 mirror should take about 40 to 80 hours of effort. While this is a non-trivial amount of time, the mirror can be completed in a few months, and certainly within a year. Most people work one to three hours a day on their mirror

The original Mirror -o-Matic had a turntable that doubled as a slurry drip pan. Because of the increased effort of removing larger, heavier mirrors on this new bigger machine, I have added a stationary drip pan under the turntable. This will allow wa shing the mirror in place and attaching a drain pipe to the pan.

Mirror Test Stand Construction Plans. The Couder Mask or Pin Stick. In order to do final figuring of your mirror with the Foucault test, you need to be able to identify selected zones of your mirror. Zones are nested doughnut shaped rings with certain radii; the central zone is a circle (the hole of the innermost doughnut). A Couder mask is a

Grinding a Mirror For it is true that astronomy, from a popular standpoint, is handicapped by the inability of the average workman to own an expensive astronomical telescope. It is also true that if an amateur starts out to build a telescope just for fun he will find, before his labors are over, that he has become seriously interested in the

Fixed-post machine grinding is where the mirror is on a turntable rotating around 20 PRM [speeds vary], and a 75% tool is on top. They are already curve-generated. The tool is hanging over the mirror by 1/6 the diameter of the tool, or about 1/8 diameter of the mirror, and is fixed in this position.

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. F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror (e.g. F/D = 8) will be performing very well on planets and the moon.

Mar 25, 2009 Fixed post mirror making machine - posted in ATM, Optics and DIY Forum: I am in the process of constructing a fixed post mirror grinding machine. This will be for grinding a 20 inch mirror. I have successfully ground a 14 inch mirror by hand. I have a 1/2 hp single phase motor, the shaft rotates at 1400rpm. I want to get this down to 40 rpm using pulleys.

Nov 06, 2020 Astro-Tel - Mirror grinding machine. MIRROR GRINDING MACHINE. I made my first mirror grinding and polishing machine over thirty years ago. It used the working principle of the machine illustrated at A Fig.3, Page 163, Amateur Telescope Making Book 1. A bowl which rotated was fitted to the spindle. I also built another machine of the same type.

A table saw covered with layers of newspaper about 1/2 inch thick (to support the mirror and tool) was used as the grinding stand. A wet began by spraying the disks with water and smearing a small amount of grit over the tool (or mirror) with my fingers.

A good starter size is the 150 mm (6 ) mirror. A 200mm (8 ) will also work. Most ATM books and websites recommend a Pyrex mirror blank, but in my opinion, annealed plate glass is better for this first, learn and practice mirror.It is cheaper, it is softer and grinds faster, needing less abrasives and with these small sizes, the low expansion glass like Pyrex has no practical (visible at

The numerical control mirror grinding machine is characterized in that the grinding head seat is installed on the polar radius translation bench through the polar angle rotating shaft to form a lower translation-upper rotation polar coordinate movement system. The numerical control mirror grinding machine is more stable in structure, high in

Grinding On the picture below the machine is fine grinding an 8 inch mirror with an 71% tool (143 mm diameter) and 9 micron aluminium oxyde. The bent lines on the mirror are the effect of the tool turning - with respect to the mirror - faster at the central part of the mirror as compared to the edge zones.

Fixed post mirror grinder advice - DIY Astronomer

Nov 01, 2011 Basically there are two types of grinding/polishing machine. The ‘traditional’ type which involves the mirror rotating at a relatively slow speed, a few rpm for a big mirror (16-20 inches) with the tool moving across the mirror, from side to side, at a higher rpm depending on the size of the mirror

I borrowed a few ideas from the Mirror-O-Matic mirror grinding machine, particularly how to mount the turntable on top of the pulley. Anyone building machinery for cold-working glass should have a look at the MOM web site and plans. There are lots of good ideas there. The
