I want to expand, approaching a bank for a loan.

Well Army I would advise you to dig a little deeper as far as the wire granulator goes, I know a few guys that have bought these machines and it was supposed to be the next new get rich thing, it hasn't worked out so well for them, there main problem was and still is they are always searching for wire, one other thing they all agree that all they strip is number one wire only,they lower grades just don't work out to be profitable, is there consensus. there are also a lot of these machines for sale all around the country with low hours the dealers will finance you with decent credit. Another hurdle to over come right now is the price of copper keeps slipping and realy shows no sign in the near furture of rebounding. As far as the X- Ray gun I bought one in 2001 when I was a yard owner, payed 22,000.00 for it then it is still working my ex partner lets me use it on samples of lots I am trying to buy or bid on, any dealer will let you shoot a sample of something to see realy what you have if they are doing business with you. They are nice to have but for the amount of times you will need it if not having a high volume yard I think it would be a very high priced dust collector. And the investment required in my opinion would be better spent on something else. I don't want to discourage you in any way, good luck to you you asked for advise and that's what I am giving you. P.S. the guys that have the granulators are well seasoned in the scrap business and all have deep pockets for purchases, money is not there problem getting enough material on a steady basis is.
