Introduction: Vice Soft Jaws - Cheap and Easy
I found these over sized erasers at the dollar store and bought a couple. I initially planned to use them for making custom rubber stamps but then I quickly realized I could use them as soft jaws for my vice. This is a very simple build that will net me a lot of use. I already had the neodymium magnets and epoxy on hand so I only spent the $2 for the erasers. I believe magnets can be purchased for about $3-4 in the hardware store. I plan to use this for my knife making. I also think they will come in handy when working with wood, since I don't have a proper woodworking bench I can use these to hold the wood with out marring the surface. I hope some of you all find this quick build helpful.
Step 1:
These erasers were flexible which I hope meant would allow them to contour to the shape of whatever clamp in them.
Step 2:
The first thing I did was to square them off. So I marked the length of my vice jaws and used my band saw to cut the excess off the erasers.
Step 3:
Next I marked the locations of the magnets. I made sure that the magnets would align with the flat portion of the inside of the vice jaws. I used the magnets as templates to mark the position of the holes. Then I took the erasers to my drill press and drilled two holes. I made sure the holes were roughly the width and depth of the magnets. This is a good opportunity to use the depth stop on the drill press.
Top tip: Use a scrap piece of the eraser you just cut to do a practice hole to check the depth before drilling the actual holes.
Step 4:
After drilling all the holes I mixed up some 5 minute epoxy and glued the magnets in place. Do not use acetone to clean the residual epoxy it may eat away at the eraser.
I let the epoxy cure for a couple of hours.
Step 5:
I tested the soft jaws and was surprised how well they worked. They gripped the knife blade well with no issues and no marring. This is a very simple but very useful build. I hope you all find this helpful.

Great idea! I would have stopped at just thinking of the erasers, but the magnets add a lot to it.

And the neat thing is when the erasers wear out I reuse the magnets.

Good idea. I think I will just glue on the flat flexible refrigerator magnets on the back side so there would be no bulges in the erasers.

I am a silversmith and often I want to hold pieces of metal very firmly in the vise. Instead of erasers I use soft mahogany wood which compresses slightly and provides the holding power I need without marring/bending the surface of the silver. I did use magnetic plastic sheet glued to the back side of the wood for holding the wood jaws in place. When the present jaws become too used, I will make new ones using the magnet idea here. Cross pollination.

Yes! I love it when ideas are repurposed.

This is a really good idea. I need to make a pair of these!

Thanks, I bought a few extra erasers so when these get trashed I can remove and reuse the magnets on the new ones.
