The mirror grinding class will meet on Thursdays from 8pm - 10pm in the club room in the basement of the observatory.
The time has come to start preparing to grind your mirror. For a good
primer on the process, read the article at:
For those of you doing a 6" or 8", we will use the glass tool method.
For Ratnam, who is doing a 10", he will be using the plaster/tile tool method.
You will need most of the materials from the list I sent out previously. Make sure you have your grinding stone, as it is the first thing we will use. Also, be prepared to carry your glass and supplies home with you, since I am encouraging you to work on it out of class, too.
Bring a marker and put your name/initials on all the objects that belong to you.
During the first class, we will put a bevel on the mirror with the grinding stone, we will choose which side will become the mirror, we will start grinding the other side (the back) flat, and we will prepare the front face of the blank to become a concave optical surface.
