Welcome from an EX Massachusetts guy- 30 years in Framingham before retiring to Maine.
Are you aware of the New England Model Engineering Society? They are a group of guys interested in all aspects of machining and precision work. They meet monthly at the Charles River Museum of Industry in Waltham MA. Thats in the mill complex that was the first purpose built mill in the USA.
Its a great group of guys. I started the group and was president until I retired, I still get there for the annual model engineering show every February.
