Thank you for the relies,
This is my first attempt at making a mirror. Even with all the
reading I have done, experience is the best teacher. This is the second
tool I have made, the first one flopped because I made the dental stone to
thick and I didn't have enough time to work it before it hardened. I try
not to make the same mistake twice. This is a learning process and I
understand this.
That is why I am working with a full thickness Pyrex, so that I have
plenty of glass to work with in my trial and errors. I have a long
way to go before I get to the point where I can some what understand the
talk on this list about testing and optical performance. So, please have
patience with me; I'm just beginning.
I will go with this second tool as suggested, and work with it
through the whole process. I will start to work on it in a day or so.
Arthur
