Are the components serialized in some way? If not, all you can do is assign a quantity to a job or location without knowing anything else about them. More focused answers will require more information from you - such as what tables you're already using to track the other tools. How do those tables interact with job (or location) tables, assuming you have those. What is the goal with equipment like scaffolding - know where the parts are or just know how many you have on hand to allocate to a new job?
The more we hear silence, the more we begin to think about our value in this universe.
