Ray,
Just a suggestion. You will have a lot of money tied up in Gold if you use Gold bolts. Most of the Gold material will never be seen, because the drilled holes will probably "milk" over and not be transparent. Unless you can polish them, of course. If I was to use Gold at all, I would use pins and pien them to get heads on them. That way, you use smaller material and it will cost less for the stock. Gold is expensive, but the payoff is that it is so soft and will work better than about anything else. This is just something to think about if you decide to go with Gold. Lin
