It is for me. Theoretically, you can pull the dial indicator apart, then replace the tension spring with a softer one. I've never done this. My machinist bought a cheap rod-bolt stretch gauge, then wanted a stiffer spring in his after using my ARP stretch gauge. I don't think he ever got around to that...he borrowed my ARP unit a few months ago.

Maybe we can get him to post the syllabus, and the textbook name and ISBN. Who knows? Is the course available online, or via Zoom or some-such?

Not to hijack thread: I will start a new thread in about a month for anyone interested. It will highlight what our 1 year long course is about. I will post syllabus and some worksheets and class notes. I have never done anything like this on a forum, so have some patience. Thanks for the interest. Students over 55 years old who live in a multi-county area around Dayton Ohio can take the classes virtually for free with some lab fees. Class fills very fast. One of the areas best kept secrets. Sinclair College is a local tax supported state school. Next class starts August 23rd. It is filled with 5 on the waiting list.
