Fridge Magnet for a Cutting Board

Here’s How This Is Gonna Go Down

This is a very simple project. Breakdown:

1. Put a carriage bolt through a magnet
2. Glue on some rubber
3. (optional) Sand blast to remove shine

Assumptions — your cutting board:

1. Has a hole in it
2. Is reasonably lightweight

Supplies

• Roll of thin rubber
• 3" Ceramic CUP Magnets
• CA Glue
• 1/4" x 20 carriage bolts & nuts (shop local!) — for my 5/8" board I used 1.25" bolts; adjust to match yours
• Cheap sandblaster (optional) — for this size of project you don’t need a huge air compressor

Stick the Rubber

Cut & Attach Rubber

1. Using an X-Acto knife, place the magnet on the rubber, then cut a disc w/ a hole in it to match the ceramic portion of the magnet.
2. Use CA glue to stick the rubber on the magnet.
3. Put some weight on it, and let it dry for about 1 minute.

Tip: Cure any uncured blobs of CA-glue squeeze-out using baking soda. Just shake it around in the magnet area and dump it out. See the video at timestamp 1:42 to see what I’m talking about.

Assemble the Hardware

On the carriage bolt:

1. Install first nut, leaving about 1/2" of bolt sticking through
2. Add the magnet
3. Install second nut

Check this: be sure the bolt doesn’t protrude past the business end of the magnet.

Verify the length works for your cutting board, then tighten things up.

Sand Blast (optional!)

I’m not a fan of shiny chrome-y-ness, so I sandblasted it using this cheap ~$25 sand blaster.

You don’t need a huge air compressor for small projects like this.

Tips:

• Use fine sandblasting media. You can get this from your local monument shop. Fine sand works better in a cheap sandblaster, and it provides a matte finish rather than a pitted one.
• Don’t blast the bottom of the magnet.
• Clean sand off the bottom before using on your fridge (unless you want scratches).
