How do you keep parallels from moving around?

[upjeeper]

what method(s) do you guys like to keep parallels from moving around when under a piece being machined on a mill?

I wring them to the vise jaws by wetting them with a little WD-40. After that snugging the jaws, seat the piece with a deadblow, then fully tighten and they aren't going anywhere.

I use extra long fabric covered elastic hair ties. Unlike rubber bands, the sharp corners of the parallels don't cut through these.

a tool room machinist gave me his parallels when he retired. they are 1/2" thick and stay put

I never had trouble with the parallels moving around while machining, it is the reseating process between parts that eats time.

I have tried::
a) grease
b) oil
c) WD-40
and d) rubber bands

None of these saves you from having to clean out the chips that can get under/behind the parallels.
The best I have found is keeping a clean rag within arms reach.

If they are moving when machining a part, then the part is not sitting on them. A dead blow hammer is your friend here.

I use a piece of metal strapping like what comes on a binding of pallet/box. Bent in a Z shape.

I bought one of these doohickeys, it works well.

Deadblow here.
Snug it in the vice and tap with the deadblow.

Only way to absolutely know the work piece is resting squarely on the parallels…

Dead blow and a quality vise. Kurt. That is if you are talking about moving while machining. If setting up too many ways to fix that issue. Take your favorite that works for you.
