Ha,ha. True. Thanks for the link.
I regret selling or chucking out all the old/out of current data manuals I had when I was working and buying the latest editions.
I still find problem solving satisfying although not wishing or able to get to heavily involved.
Recently I was with a friend who has developed an interest in
Cycle motors (1950s bicycles with engines in the back wheel) amongst other things. He wanted to visit a local scrapyard and whilst wandering around I noticed the owner doing repairs on his old Iveco Recovery truck, I mentioned I had had a few , so he started talking about some issues he had with it. I glanced under the bonnet and was able to straight away find one of his issues, which he appreciated so soon it was hard for my friend to drag me away.
