Charlie,
You are selling your scrap at the bottom low of the market right now.
I assume you have a scrap dealer who either provides empty drums or a 4x4 or 4x6 bins for you to accumulate the aluminum turnings.
The buying of scrap turnings is sort of a pecking order, the street vender buys from you for $0.10 lb for your 500-1000 lbs, then sells it to the next guy up the chain for an additional few pennies a lb along with tngs from his other customers for that day or week, then it goes on to another guy for another few pennies more until it ends up with the company who collects enough to make bails out of and then it is sold to the final guy who melts it all down and makes another inget or block of aluminum that you then pay $1000 for so you can make a new intake manifold out of it and start the process all over again.
It's a big circle, but places like Boing are NOT building many planes so the companies that build parts for the planes are not buying metal for manufacturing and so forth down the line.
