Disc Mount - Store and Display CDs on Metal Surfaces

A disc mount is a small, magnetic holder for a CD to solve an access, storage, destruction problem we ran into time and again in our gaming area. Now we can store our discs on nearly any metal surface and rearrange as needed. The convenience and flexibility has resolved the problem. Learn more on our Disc Mount Project Page. In our case, we modified the back of a poster with tin to give us a fun display to store our discs. I show you how to do this poster frame mod in the instructable, Poster Magnet Board.

This instructable shows you how to create a disc mount in less than 10 seconds and how to use it.

Learn more details on the project page.
See more pictures in our Disc Mount gallery.

We designed the disc mount to securely attach to a poster, with an acrylic face up to 3/32 in. thick, upside down, holding a CD. (Hey, you never know how people might attach their CDs, right?) So, the strength of these are over-kill for attaching directly to bare metal, but works great for metal covered with materials such as laminate, fabric, vinyl, acrylic, etc. To build a disc mount you will need the following:

Note: Some products purchased through these links may earn me a small commission to help fund further inventing to share with you. Thank you for your support.

• 1, foam cd hub (0.52 in. diameter x 0.375 in. thick)
• 1, nylon washer (0.85 in. diameter x 0.395 in. diameter hole x 0.062 in. thick)
• 1, neodymium magnet (Ni-Cu-Ni plated, 0.375 in. diameter x 0.062 in. thick)
• 1, white vinyl sticker (0.75 in. diameter)

Be aware that safety is your responsibility. Please read our Safety Warning and Disclaimer before you start.

Foam CD hubs come with one side that is sticky. Place the sticky side of the foam hub onto the center of the washer. It doesn't have to be perfectly in the center, just close. To make sure the adhesive sticks, apply firm pressure between the foam hub and washer for 2 seconds. Do not flatten/crush the foam hub.

Flip over the hub-washer assembly. Place the magnet into the hole in the back of washer-hub assembly. To make sure the adhesive sticks, apply firm pressure between the magnet and foam hub for 2 seconds. Do not flatten/crush the foam hub.

Place the sticky side of the vinyl sticker in the center of the washer to cover the magnet. This doesn't have to be perfectly in the center, just close. To make sure the adhesive sticks to the washer, apply firm pressure to the vinyl sticker in a circular patten.

Congratulations! In less than 10 seconds you have built a disc mount.

Your disc mount can stick to any metal surface that contains a significant amount of iron (galvanized steel sheet, for instance). Examples of metals that will not stick are:

• aluminum
• copper
• nickel
• titanium
• most grades of stainless steel
• brass

Place your disc mount on a metal surface by holding onto the outer edge of the washer while bringing it very close to the surface. Release. To remove the disc mount, grab onto the outer edge of the washer and rock it forward from one edge. (You may need fingernails to get leverage.)

Do not remove the mount by pulling on the foam hub.

Align the hole on the disc with the foam hub on the disc mount. Gently push the disc so the foam hub passes through the hole and rests against the washer.

Using 1 hand, rest your thumb on the edge of the disc and place your index finger on the foam hub. While holding the foam hub in place, pull your thumb towards you while dragging the disc off the foam hub.

OK, now where to mount those discs? I like using posters that have been modified with a tin backing. I show you how to do that in the instructable, Poster Magnet Board. Otherwise, attach them to common metallic items around the house or build your own cool display. Lots of possibilities...have fun!
