I really like free and made with left overs. Thats a pretty good use of packageing material. I usually pick up any scrap I see laying around. It always comes in handy sooner or later. I picked up a couple of old 2.5in shafts that where left after a part change out. They stood in the corner of my shop for 4 or 5 years. Never had a use for them, but knew one day they would come in handy. When i bought the cyl for my processor build, the pin size was way bigger than I thought. Setting around wondering where I would find pins to fit, I saw those two pieces of shaft standing in the corner. Picked one up and surprise, a perfect fit. I made 2 pins out of the shaft and still had several inches left over. I sold a extra cyl to a guy in Athens ga. He was looking at them and said, where am I going to find material for pins. Duh, walked over to where i had laid the piece I had already made 2 pins out of and handed him the leftovers. Instant sell and he bought 2 of the surplus cyl. One mans junk is another mans treasure, Repurposeing otherwise scrap or junk into something useful is the best recycling there is.
