Hello Martin!
I don't think thats an unusual situation on this forum, plenty of ex-engineers introduced to it through their trade of any sort. electrical, mechanical, cnc operators, carpenters, welders, shot blasters, bar loaders, assemblers and deburrers you name it,
also a decent bunch who don't have any connection to the trade at all, some how miraculously discovered the wonders of engineering maybe through model making or sheer curiosity.
I myself was sucked in by the delight of anything miniature or mechanical in nature, and through the trade.
Enjoy =)
