I'm sure we all have different 'first' memories, but mine happen to 
be sitting at a table placing 'T' and 'U' shaped laminations into 
bobbins that my father had wound on a winding machine he had made. 
This was as a 2 or 3 year old c1950. The transformers were bound for 
his, again homebrew, televisions using EF50 and SP61 valves (tubes). 
Naturally he had to place the final few laminations.

While I don't think this did me any harm, others may disagree!
