 Bolts?? I don't need no F'n bolts. Bolts are for guys who don't know
what they are doing and will need to replace/repair parts!!!

------------------------------------
I didn't need bolts either once past the prototype stage, spotwelding may be faster and cheaper. On a new project I almost never knew what I was doing until I studied the problem and built enough to experiment. That's the nature of R&D. Design for manufacture follows after confirming that the prototype works well. Often design engineers "throw it over the wall" to production engineers instead of collaborating. That's why I learned machining processes and limitations.

Custom production test stations for automotive electronic modules were usually one-offs or small batches and had to keep up with evolving customer requirements as they found issues with their own prototypes, so I had to make the first and only attempt look professional, meaning neatly painted and labeled and easily rewired. All electronic and mechanical components had to be bolted or screwed into tapped holes in the painted frame, and sometimes moved for late changes. That was just before PLCs and DIN rail made the task easier.
In the mid 1970's there were no experienced automotive electronic engineers, they were all new hires learning practical matters they hadn't in school by trying to keep up with changing government safety, emissions and fuel economy regulations that sometimes conflicted. 5 MPH bumpers added weight, the best economy setting turned air into nitric acid pollutant. The intake air flow and exhaust oxygen sensors were from chemical instruments I was familiar with.

That's typical of when the government's failed trial lawyers meddle with science or engineering. Yet they scream of injustice when industry lobbyists fight back. Mitre and other quasi-private .orgs attempted to isolate us from their amateur technical bumbling while trying to solve public problems involving GPS and air traffic control etc.
A group of auto execs flew into Boston and drove over an hour to central NH with a warning buzzer blaring because they didn't know how to silence it. When they arrived we earned confidence (future orders) by unplugging the buzzer and disconnecting the load switches under the seats. They were contracting time-critical projects to a very small company in a state not widely known to be so high tech.
