I have never used a milling machine, so be gentle with a nidiot. The parallels sit in the machine vice, so one must assume, and hope, that the base of the vice is trammed (right word-ish?) to the spindle or cutter. Therefore, couldn't two pieces of metal bar be clamped in the vice and the edges machined as one, then turned over so that the machined edges sit on the vice, and then the opposite edges machined as one. Would that produce two identical parallels, or am I missing something? Blocks would have to be placed each side of the bars to keep the cutter from damaging the vice jaws.

That's a lot of parallels. Why do you actually need so many Jo
Nice set of parallels! You'll enjoy having a nice set like that.Quote from: Jo on May 16, 2023, 05:38:37 PMThat's a lot of parallels. Why do you actually need so many JoHmm... Well, I don't know about you, but I'm always trying to find the parallels that are BETWEEN the sizes that I have I have some 1/2" wide parallels, some 1/8" wide and some 1/32" wide parallels (oh yeah, and some wavy parallels) but they all come in 1/8" increments. And when you're working with small parts, sometimes 1/8" is just TOO big of a difference. I need to be able to hold onto the part in the vise but the place I want to mill has to be above the vice jaws. And with small parts...For me, having more heights and widths is a great thing.Making a specific holding device for the part at hand can also be a good choice, but tends to be somewhat more work.Kim

I occasionally suffer the Tool-Envy-Syndrome over adjustable parallels, but have saved the money and still been able to get what I want done. Can anyone comment on why I might also want to decide to need those?
. Sort of a quick and less precise version of Jo-blocks.
