I spent a fair amount of time around a machine shop in my career as well as : Concrete Pumps , Construction Equipment , Ag Equipment , Diesel Engines , Big Transmissions , Ag Tractors , and many machined parts both made in house and purchased . The box smelled to me like machining oil mixed with machining coolant with a slight hint of Cardboard .
What reminds me of my Dad is : Your posting and I thank you very much for that /// and whenever I use his old Hawkbill Pruner knife that he used as an Electric Lineman .
The day he retired , he climbed the tallest pole in the downtown area of Crothersville , Indiana and nailed his hard hat on top of it.
And you really don't know how much I have enjoyed answering your post . Thank you Sonny !!!!
