Non marring vise jaws - what do you guys use?

I should add that I'm using my mill for this, although any info about lathe chuck mounting would also be helpful.

Regards,

Wood, lead, various plastics, even aluminium, if kept clean. Nice thick rubber may be an option.

In the mill vise I use notebook paper to prevent staining and marring of delicate materials.

Peter,

You ever race Honda autos??

In SF area?

Pedro

Yes....

Wasn't it always said in these types of situations, "You have me at a disadvantage, sir"?

How do I know you?

Peter

Did he use the copper pipe instead of flat stock for a reason, or was the tubing just an easy source of material?

Peter

I'll try it. Thanks,

Hard plastic shimstock, fastened in place to the milling vise jaws with double sided tape.

The usual soft metals or firm plastics in thin strips. Aluminum from old instrument cases, the kind that has pebble-grained vinyl bonded to the panels. Automotive wet/dry sand paper, with the plain paper side against the workpiece, and then cleaning the abrasive particles off the vise when done. Fibreglas tape or circuit board stock, foil tape, heavy paper stock such as file folder paper.

I'm wondering what might be the problem with the hardened, steel jaws in your machine vise. Assuming that is what your have, that is. Are the parts an odd shape or very delicate? I often use alum soft jaws cut to the desired shape to hold the workpiece. The main thing in not marking up your parts is to keep everything CLEAN. That doesn't mean just blowing air, though that is often all that is needed. You must have the part and the jaws absolutely clean, no residue. Also, a vise can generate a lot of clamping force, don't be ham-handed. There is a time and place for leaning on the handle, and for not leaning on it. If your jaws have irregularities, that may mean there are depressed and protruding deformities. Use an Arkansas stone to rub out high spots. If you don't have one, or one in good shape, use a tool bit (lathe) and wrap some fine emory paper around it.

Good luck with the cosmetics, a little care and you should get nice results.

I used a couple of layers of duct tape over the jaws of my "little" bench vise yesterday while making a "spoon ring"for that guy who asked for one one here last week.

I was curling a flat sterling silver cutout around a piece of duct tape wrapped

In bench vises, I've used leather backed by plywood, sections of small extruded aluminum angle, chunks of rubber from heavy truck mud flaps and some magnet-backed nylon jaw faces made for the task. In a machine vise, I haven't used anything. I suppose some copper sheet shims, if clean on both sides, would work. Any of the things I've used in a bench vise might let your piece wiggle around too much at the wrong time in a mill. If your machine vise jaws are clean and smooth, there shouldn't be much for marks left on the workpiece.

Often a thin sheet of paper helps the vise hold the work and prevents marks too.

Hey Peter,

In the milling machine vise, two if it's flaaaaattt, or three if it's not quite, pennies. Works a treat. Use the pennies under the work too, for clamping to the table.

And to get something small in place in the bench vise, put it in Silly Putty and then squeeze. It's like having four hands!

Take care.
