Ray -
I scrounged up some of my own SS and fabbed a bracket for you. It is the last of the material because it can no longer be legally removed from the mill where I work. They shut down every historic accommodation in that regard last week. They call it Homeland Security, but I believe it to be a tuneup for the forthcoming labor negotiations.
Anyhow, I got your damn bracket at the house. Best I can do is get it to one of the ifishers at the dock this coming weekend. I work too early/late to make the post office, and my wife is too busy/grouchy to ask.
About the mounting board. The one I had on my 22 I bought. Everyone else has made theirs. It is easy to do. But, if you want me to make you one at work, I will need a security bond up front. I figure, discounting the fringes, I will make right around $1 million in the remainder of my career. I can steal you some fancy plastic material, and if I don't get caught it will be free. But if I do get caught I will need the million bucks ASAP. So, do you feel lucky?
Who knows, that 316L Stainless Steel bracket, being the last of the breed, might be worth a million some day!
