I seem to easily blow my stack when the parallels fall over in my vice and have used all kinds of keepers in the past. I have found some tiny magnetic keepers that seem to do a great job because they are magnetic. They stick where you put them in the vise and grab the parallels and hold them in place. They are pretty inexpensive too, and their bright red color makes them easy to find even though they are tiny. They are kinda cute, too.
They are called Magkeepers.com. and I got them from EBay for $15.00 for 4.

How long does it take you to clean the swarf from them when you mill ferrous stock?
-
A piece of low density foam rubber might work pretty well. Otherwise a couple of springs might do the trick. And maybe a bit of double sided adhesive tape could keep the parallels positioned on the opposing jaws.
I agree that magnets might get covered with swarf and be a nuisance to clean.

About 2 minutes, and its almost as tedious as the other methods of holding, but not quite.

I use a piece of that flat springy steel banding, bent in a wavy shape. Material's free and I can make 'em when I need
to for any application.

These came with my vise. Work perfectly. Spring loaded.

I gave one of those away recently

Yabut, for $60 a pop...

for a couple of sliding members and some springs, I'll stick with my shade-tree solutions...
Dab of grease or cutting oil and "stick" parallel to vise jaw
or
Piece of foam/sponge/whatever between parallels - self-adjusting and cheap enough to be disposable when grotty.

Since my vises are 1", 2", and the big one is 3" those spring loaded keepers are in the way and don't really work all that well. Tiny mags for me.
What works for you is fine with me. Just sayin...
Marv, you aren't going with the digital.

Each to there own methods and there's been multiple designs I've seen as parallel keepers. But I'm with how Marv does it. A few drops of oil or little daub of grease sucks the parallels tight to each jaw face real well as long as the jaw faces and parallels are flat and smooth. But that's required anyways. No chance of chips getting under or behind them either if there stuck down properly. And I've yet to have a chip brush move them in the slightest. Those old school machinists knew how to get the best out of what they had.

I just set my parallels in place and they stay there. However, I was looking at machining sites (somewhere) today, and seen a vice with parallels held in place with rubber bands, which I thought was rather novel.

I did that. It can work but I found it a bit iffy. My rubber bands were a bit tight and during machining they would suddenly let go (i.e. break) and go flying.
Scares you for two reasons...1) you see something flying by and wonder if it's a bit of tooling or part and 2) the parallel moves at the wrong time into the wrong place. I think a bit tight. Would have probably been okay if they'd had less force.

In a big shop, do they tell the new apprentice to hold the parallels in place for them?! :o

You can put magnets into small plastic bags that have the zip lock type ( press together ) fastening; then when done unzip bag remove magnet & the ferrous cuttings drop off the bag :thinking:

Hi Guys & Girls,
I was watching a You tube video the other day. The guys solution to this problem....... :noidea: use a couple of rubber bands one for each jaw! Stagger the bands & you can get almost to the thickness on the bands
Cheers Kerrin

I use the steel banding from crates. I've been using the same 6" piece for years. You can bend it to fit in gaps from 1/16" to about 2".
