Phil you have just inspired me to get back to work on my 5.5-inch. I've been so discusted with a hole in the center that I was about to drop it on the concrete floor and start over. I will, but go back to 600g or 25m, get the focal length a little longer. I've only been trying to finish it for a bout a month now, but was planning to wait until summer.

Say, I have a question for you atm'ers: What do you do with used pitch? I'm not planning to, but can it be re used? How many times, if at all?
