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.
Unless you get the pre-generated blank. No hoggin necessary.

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.
I had one of Dans 8" F/6.7 mirrors and it was one of the best 8" optics i have ever owned.

has anyone compared a Zambuto against a Waite mirror? ... contrast?
Rob Teeter built an amazing scope for me around a 12 inch gordon Waite Mirror. He also was coompleting a 12.5 with Zambuto Primary. In a side by side comparison he felt this particular Waite mirror was the equal for that particular Zambuto. Here is a link to his post:
Waite versus major Mirror Make Mirror
In the interest of full disclosure. gordon built this particular mirror for his persoanl scope and used it for 5 or 6 years (as I recall). He was going bigger/faster and I had the good forutne to purchase it from him. It is a "work of art" (quoting Rob) built on 1 inch thick pyrex, mounted on an 18 point floatation cell with a Howie Glattor sling.

I really like that. I think this is one of the things that has kept the German economy in decent shape ( that and not spending beyond their means). Of course to keep quality producers alive, we must insist on buying quality.
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.

That thinking has become been the American way and has spawned the proliferation of such things as fast food industry, big "box" stores, chain stores, etc..
