I'm not a professional Machinist either (but have many of the professional skills and have honed them over my lifetime of using them), but I did take 2 semesters of Machine shop in HS operating pretty much any machine (lathe, milling machine, shaper, drill press, arbor press, etc) you would find in a machinist's shop. I operated my Dad's South Bend Lathe many times when I was growing up (wish he never sold it as I would have really appreciated inheriting that) and I have many of the tools and some of the equipment you would find in a real shop. Regrettably I no longer have access to a lath or milling machine but I do have a very accurate floor model Drill Press, a slew of just about every size of Taps and Dies, some Reamers and obviously a wide array of measuring instruments, gauges and comparators.
These days I mostly use the skills and tools I have to refurbish and repair the personal items we all join this forum to discuss as well as many other items for automobiles, motorcycles, machinery etc. I also invent things and have many other hobbies. Some here know I am a huge Lionel Electric Train enthusiast and there have been many many times I've had to make or repair parts for vintage locomotives, rolling stock and accessories. I also enjoy refurbishing and restoring early 20th century electric fans. There have been many times I've had to make gears, knobs, springs, etc. to get those items back into like new condition. While I've never sold any, I have fully restored lots of them for gifts to family and friends.
When I was in my own business I often had to make parts for machines and tools that broke down as I could not wait days or weeks to get a particular machine or tool up and running once again. Time is money!!
Micrometers, Calipers, all kinds of quality tools that I own really help make the job easier and more precise.
