I gather there was some of ingenuity in the British defence industry as it was being benevolently managed by the Government through the 1960's and 1970's ish. Someone with a Trade background running a facility described maintaining a small "free-standing" workshop offline to the production, where if one of the "boffins" turned-up with an idea, that "boffin" could try to make it, mentored by technicians, getting all the wisdom, and "see where it went". Best wishes --------------------------- In the US that would be a toolroom or model shop. In my experience the primary machine tool was a Bridgeport or clone, doubling as the drill press, a lathe was optional. For newer machinery the rotating wear parts a lathe can make usually could be bought. For making my own designs from scratch at home that's reversed. The instructor for the ham radio course at Mitre was a retired British radar boffin / wizard who was still actively experimenting and building exotic hardware. Some of it looked like musical instruments because microwave band wavelengths are similar to those of sound, and brass is sufficiently conductive and convenient to work with. Usually the Ph.D gave me a sketch and the data sheets of the critical parts he had ordered, then left me alone to implement it. I suspect they didn't want to embarrass themselves by revealing they didn't know the practical details or methods, I also resoldered stuff their kids had broken. By being able to do the mechanical fabrication as well, sheet metal enclosures and milled microwave or optical housings, I avoided the inevitable disagreements and delays of depending on another tech or shop. https://www.linkedin.com/pulse/manufacturing-vs-design-which-really-harder-i0b7e "Plans rarely survive first contact with the production floor." "Design often sees manufacturing only when something explodes" The auto exec Ph.D from India whose antilock brake controller failed to pass specifications didn't know that available resistors have tolerances, he expected 8 digit precision of the 2nd order wheel deceleration curve and its detection. The mechanical engineers at Segway were much more hands-on, I often had to use their manual or my own machine tools because the CNC machines were busy. The old car I'm fixing suffers from shortcuts that let water enter and collect where it shouldn't. For instance a moderate buildup of tree debris in the cowl will let water flood over the low cabin air intake lip and pool on the passenger floor. The cowl end drains allowed water and debris to enter the areas that rusted. Cleaning the cowl channel meant breaking some of the snap-in plastic retainers the dealer charges several $ apiece for. They are now all stainless screws and U clips. The push clips are tolerable to install and remove if stainless screws replace the plastic expansion pins. I attend classic car shows to learn how others made repairs. Too often I learn they were skilled at writing big checks.
