I'll tell you what is pretty valuable right now is scrap iron. The other day we cleaned the shop up and took Dan's damaged 455 empty block, and the old motor and compressor from our air compressor to the scrap yard. I was expecting maybe $ 30 or so, but we got $ 65.00 and it was not all that heavy.
I'm thinking about going in the scrap iron business. My girlfriend and I used to be in the iron and steel business............she took in ironing, and I would steal !
(Yeah, I know, 3,000 comedians out of work and here comes one more. )
