I agree, but also add to problems at the training colleges, again, very "male" orientated behaviour, with lots of "laddishness", male "banter", sexual innuendo, etc. My niece tried to learn there to be an electrician, but just couldn't cope with being in a minority of women and a very male dominated environment.
In our village, we have a small "grease monkey" garage. Basically handed down through the generations, great grand father, grandfather, father and son all worked there for a short time. The it was just the father and grandfather. The father had two daughters. Both were keen to come into the business and ultimately take over. Both went to college. Both gave up very quickly due to the male dominated behaviour etc. Instead, they just worked at the garage under the father's training and supervision and gave up on the college side of things. Both have now jointly taken it over, father is poorly so has taken a step back. They're both doing exactly the same as before, full garage service.
People keep going on about strength, but there are ways to mitigate it for someone who maybe not as strong. You can get lifts, hoists, trolleys, ramps - even "big strong men" use them! You can get power tools to take the strain of stuck bolts! A typical woman is perfectly capable of lifting a tyre which is probably the heaviest thing a garage mechanic has to lift on a daily basis. Most other motor components are actually pretty small and light. Two women together can lift even the heaviest things they're going to have to deal with. Even "big strong men" need block and tackle lifting gear to remove an engine. Same with the fire service these days, previously thought to be a male dominated profession, but now women have proved to be equally capable - fire engines carry hoists and lifts and other aids to get the heavy equipment on and off the engine etc.
The REAL issue is the male dominance, poor male behaviour, poor male attitudes in "male" trades towards women, etc. Get over that and women can do exactly the same as men.
