advert. Apparently General used to age all the castings to allow
stress relief before machining them. The quality of their table saws

i saw on some vendor site future metal lathe parts
they season them outdoors for months and years before they finish
them and make them into lathes or mills etc

i doubt the stuff made in china is seasoned before they finish them
