Magnetic Swivel Base Vise Mount




About: -----------------------------------------------------------------16 year old, sick with a deadly disease called DIY-itis!-----------------------------------------------------------------Hi FTC! My I'bles con...

In my last Instructable, I showed How to Make a Wooden 6" Vise. The vise has turned out way better than I thought, so I decided that I want to mount it, which caused some problems:

I didn't want to use clamps, but wanted to mount it firmly onto my workbench, and also wanted to use it as a Drill-Press Vise. I also wanted the mount to be be able to be released quickly ("Quick-Release"), so I would be able to switch between both options quickly.

I decided to make a quick release vise mount with a big speaker magnet. What's also nice about a magnet its that the vise can swivel, if needed.

Let's get started!

Step 1: What You'll Need:

Hardware & Materials:

Some plywood

Microwave transformer


40 Grit sandpaper

A strong speaker magnet

Chemicals & Adhesives:


Alcohol pad

Wood glue

Tools (+Attachments):


Mixing stick


Electric/Power Tools:



Recommended Safety Equipment: Earmuffs, Respirator

Cost (for me): FREE!

Difficulty: Fairly Easy

Approximate Time: 1 Hour

Step 2: Choose Your Magnet

Choosing the magnet- The most important part.

You need a big and strong magnet that will be able to hold the vise onto the transformer. I used a magnet that I salvaged from a siren, but any subwoofer speaker could work too.

Step 3: Roughen the Surface of the Vise

The magnet has to adhere really well to the bottom of the vise. Since I applied varnish only a couple days ago, it needed to be removed., which I did with 40 grit sandpaper.

Step 4: Cover Up the Dado's

The wood that I used for the vise was reclaimed from an old table, meaning that it had two grooves across the whole piece. I think these are called woodworking dado's.

Since I had already roughened the surface, I glued on a piece of plywood that I had previously cut to size with a Hacksaw, and clamped it firmly to the bottom.

You probably won't have to do this...

Step 5: Glue on the Magnet

I mixed some 2-Part Epoxy, smeared it across the back part of the magnet, and clamped it tightly onto the plywood.

I left it to cure for several hours.

Step 6: Mount the Transformer

I recently built my own weighted workbench, so I wasn't worried about the weight of the transformer tipping over the workbench.

Since all of my small Drill-Bits were dull, I mounted the transformer onto the table-top with 2 screws. No pilot-holes, and no countersinks...

I did this while waiting for the Epoxy to cure.

Step 7: Use It!

I know this quick project might not work for everyone, but it works really well for light duty Bench-Vises. It all depends on what magnet you use. Just make sure that the magnet isn't too strong, or else you won't be able to remove it...

You can see that I'm using it for both on the picture

    I thought u would use the transformer primary as an electromagnet!

    heheheh I'm not kidding! If you remove the secondary, it's a nice electromagnetic mount. I've done it myself. It's even better if u rectify the input!

    Never turn it on with the secondary in place!!!

    I know! I've seen Colin Furze make his electro-magnetic shoes, and thought about this when making this one

    See my reply to BeachsideHank below...

    I've actually used two more of these to add more weight to my tables, so... I could put them in series! ;)

    I'm still (not) waiting for someone to come here thinking this is an Electromagnetic mount, since the transformer is in the picture...

    If you hook 'em up in series, then you've got the legendary microwave transformer stick welder.☺

    I think that if I'll hook them up in series, I'll have ~6,000V.

    That sounds like a nice taser...

    what is the reason for the transformer? just as another magnet to attach the magnet vice to?

    Nope! I just like using microwave transformers for everything :)

    I used the transformer because the magnet attracts with way more power than any other piece of metal, it's easier to mount to the table, adds more weight to the table, can be used as an Anvil, and because it has a pretty wide surface area.

    You can use any piece of sheet metal (preferably something thick).
