Well, I've certainly inherited the practical gene. Some of it anyway.
My Dad was a Chartered Electrical Engineer, but as he was an MoD scientist I don't know what he actually did to help Defend the Realm, only that Electrical Engineering is lots of Very Hard Sums. That was an ability I didn't inherit!
Dad did encourage me though, and my 18th birthday-present from my parents was an EW 2.5" BGSC lathe he'd bought from a work colleague. I still have it, but the poor thing has a very basic, rather flimsy headstock now quite noticeably worn (you can see the chuck jumping about), and I'd love to bring it back into proper condition but am not sure how without excessively compromising its strength and design integrity. Consulting the Oracles (aka Tony Griffiths), I was delighted to find my example has all of the optional-extras offered by EW Stringer, except the change-wheel guard.
Yet the engineering side of the family was Mum's: her brother was a professional engineer in British Railway's Technical Centre in Derby – and Hon. Sec. of Nottingham SMEE for many years. The first miniature loco I drove was on that Society's original track, for a lap or two. While Mam's father or grandfather (I forget which) was the Kay of the eponymous bicycle manufactured in the Nottingham factory he established.
Our Mam always reckoned we're descended from John Kay of very early Industrial Revolution fame, though we've not been able to verify this family legend, and apparently there were two, non-related but more or less contemporary, John Kays separately inventing early textile machinery!
