Quote:However, I have to wonder if myth is starting to overtake reality.
Quote:I've turned the idea over in my head from time to time and I would t bother with anything but a big mirror like 12" to 20". But when I learned of the sheer mountain of hours involved between hogging out the glass and such. It kinda killed it for me. Bless anyone whose got the time but between two jobs I can't swing a 300-500 hour chunk of life on such a thing . And smaller mirrors I have no need for. I regret its too much to take on. I have a fine hand for those kinds of things too.Pere
Quote:Right and a great example is Dan Joyce. He has had an optical shop in the Chicago area for decades and offers mirror making classes to anyone who wishes to make a mirror. He just had some high school students in his shop the other day wanting to make a 10 inch from their blank. There are a number of locals who have made many mirrors with Dan.
Quote:has anyone compared a Zambuto against a Waite mirror? ... contrast?
Quote: I think that some producers don't know how to do it any other way - I always tried to convey to my sons that doing a good job is a way of life.
