I run a free tool-lending library from two converted garages. Borrowers often arrive asking for the most powerful machine, although the real question is what material they are working with and how accurately they need to cut it. We insist on a short demonstration before certain loans, not to create a barrier but to discover whether a simpler tool would be safer and more useful.
My background in logistics helped me organise stock, yet the difficult part is tracking condition rather than location. A returned drill may be present on the shelf but unavailable until a worn cable is inspected. Availability is therefore a judgement, not merely a count.
Borrowing records also show where demand repeatedly exceeds supply, but we do not convert this automatically into purchases: frequent requests may reflect poor advice, a local building project or one borrower repeatedly choosing the wrong tool. A loan can be refused with an explanation and an alternative, making safety a shared judgement instead of an unexplained institutional veto.
