My Dad who is now 95 used to fix Spitfire engines after WWII as he was trai ned by RR.
As a fireman in civvy street, he built me a 8.5?? reflector out of plywood that he made into a telescope, plus an observatory and moto r drive for it, a garage and extension bedroom on top all wired in and with a fire sprinker.
He could tune 4 pot bike engines by ear with a screwdriver held to it and h e rebuilt his Alfasud boxer by hand after wrecking it by redlining it.
He tried to teach me about engine maintenance, but my scientific mind was m ore into Astronomy, Physics and Chemistry where I made my 40 year ? career?, but bits of his talent have been passed on thankfully whic h I now employ around the place.
Not his woodworking skills though.
