I was hunting for a use for my old 1-1/4" band sawmill blades. Thanks, Bob! :beer:

Most of my working lifetime, was spent, milling. I never, used purpose made parallels........
I used lengths of key steel , of various cross sections. Also, many miles of "Bob's", steel banding.
When I retired, several yards of the material retired with me. Still have a few feet left. :thumbup:

DavidD -- As an apprentice, I made my own set of parallels. That was one of the check-list items in those days. It was my introduction to using a surface grinder. Over the years that I worked on contract in various and widely spaced shops, many of that "set" sprouted feed and I broke down and bought a set from the widow of a colleague. That is supplemented by several matched pairs of custom parallels made for a specific purpose.
I also have two sets of adjustable parallels. The first set I had were made by me, but this disappeared in a move. I find it interesting when I see people working on jobs that, had they a second set of adjustable parallels, would be much simpler to set-up.

Very few jobs in a hobby workshop need any more accuracy in a parallel than can be got from cold rolled stock cut to length.
OK there are times when you do, but they are rare as cold rolled stock is amazingly accurate over a shortish (6" or so) length.

Getting a bit off topic, but I also hear that dismantling bearings yields very accurate spacers...
