Another with the main door open to the optical shop, with some scopes parked there.

And finally, here is one of the 18" mirror I was grinding out, while we were viewing.
The machine just ran, and ran, while we viewed, and aligned. We eventually turned off all the lights, and the machine when it got darker. Thanks for peeking in. Rob GOMOC

I just saw that last photo after my previous post. That looks like you have it on a drill press? I take it that means you can grind flat mirrors but not convex mirrors?

Notice the symetrical polishing parks on the mirror? I was working on just outside the center. I'll post a better image of the machine later. Rob |

It's in my scope garage/mirror making shop. Rob

This might be a dumb question but I know nothing about all of this.
Do you have the ability "in house" to apply the reflective coating as well and do you use aluminum or silver? -------------------- Ron Walker

The mirrors will all be sent out for aluminizing/coating. Rob |

"No Ron, I simply cut, grind, and polish/figure."
I've not cut, but I have ground and polished two mirrors, a 6" and a 10" and I can honestly say I would not use the word "simply" to describe the process. Not hard, but not simple either. A machine would have been fantastic! Steve |

Steve I did use the word *Loosely*  However....Cutting is time consuming(not hard), and grinding is time consuming(not hard), and polishing is tricky(not hard), and figuring is challenging......To say the least.
