I have a theory on this. Once I divorced I had to actually pick up drill and use it myself rather than watching my exh make a pigs ear of things, silently not to dent his ego.
now I’m a reasonably skilled needlewomen. When I make something up from fabric to join it to other bits of fabric, I can look at my handy guide made by needle makes all over the world, and use that to select the right needle for the thread and fabric and purpose I need. The colour codes are same wherever you are in the world…all very sensible . I then have other guides showing me how to adjust foot pressure with lovely pictures showing various scenarios and what to do with dials. Simples.
so, I tootled off to diy shop to get equipped with a new electric drill, some drills bits and screws and raw plugs. “How hard can it be?” I thought to myself. “Ex made such hard work of having gerzillions of raw plugs, screws and always seemed to get it wrong and drill a hole too bog or too small” . I thought, I m going to equip myself with nice sets of matching raw plugs and screws for every scenario I need in my new house. 🤷🏼♀️ What I discovered was every manufacturer of raw plugs uses different code systems and colours, and there are no universal guides to matching screws with drill bits with raw plugs for different walls. there are guides that cover some systems, but no one unifying system . Readers, how stupid I was 🤦♀️🤣🤣🤣🤣🤣🤣
so I figure it’s to do with keeping a “profession” or “trade” closed. Builders will, over time get to grips with the various options by experience, and a lot of “well love, it isn’t that simple”, “it’s an art not a science” and therefore keep their trades closed and make everyone else trying to get to grips with it, including DIY, look like incompetent idiots. And that keeps the money flowing to the trades. How many women here have refused to let their DH do stuff cos they make a balls up of it and get a “professional “ in (Or vice versa)
whereas, sewing is not a ”Serious” profession or trade (literally guilds didn’t start till Edwardian times) , and the “little womin”, have small brains so we (manufacturers) have to make it simple for them. Yes, we’ll come up with a simple colour code and numbers and guide and they’ll be able to get it right.
I do now have my own handy chart for my house . Walls differ so I have rooms, walls, type of raw plug, colour, screws and drill bits all nicely spreadsheeted. But then I’m nearly OCD and bloody minded not to let the bastard manufacturers try to make it impossible 🤷🏼♀️
but, that’s just my theory 🤣🤣🤣🤣🤣
