1. Flat bins like
these. Excess should be stored elsewhere.
2. We put a big pile of them into a tote, with an inventory, and put them into storage. If we need something we look at the inventory before hunting down the bin.
3. Wood, we toss pretty easily. Metal, if it is shorter than a bin, it generally gets recycled, but some shapes can be kept a little bit shorter. It depends a bit on the value of the piece and its condition.
In general, we have a scrap bin where we go for bits and pieces used for prototypes and such. If it is just a small cutoff it goes in the recycling bucket, otherwise in the scrap bin. At the end of the year, or when the bin gets too full, we sort, shorts get tossed into recycle.
4. If we can't use them for practice, we offer them to team members with the caveat that they must use them for something.
