Push pins are usually used to pin notes to a cork board. it's aesthetic and organized, but a magnetic board is (in my opinion) more so, and it's safer for kids etc.
I, personally, like a clean and uniform design. I don't like a refrigerator full of weird magnets, but sometimes you gotta hang something on there (e.g. shopping list, a note for a roommate etc.), so i thought " i wish i could use something like push pins instead of all those food delivery magnets" and then it came to me - why not use push pins?
In this instructable i will show you how to make magnetic push pins to use on a refrigerator, steel door or magnetic board.
I hope you enjoy this simple, short and fun one.
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Materials and Tools
1. push pins
2. neodymium magnets (a.k.a earth magnets) the same diameter as your push pins. (the same number as your push pins)
3. Epoxy glue
4. dremel with a diamond cutter or grinder bit
5. wire cutters
Step 2: Circumcision
we need a flat surface, for that we need to remove the metal pin.
(USE SAFETY GEAR)
i recommend using a wire cutter to make the initial cut as close to the base as possible and then grinding the rest with the dremel.
i tried cutting the metal pin with the dremel but the friction caused the metal to heat and melt the plastic around it (not a big deal but makes things harder)
i recommend using a bench vise to hold the pin in place while grinding.
Step 3: Glueing
mix the epoxy components, glue the magnets to the pins and let it dry completely.
the remainder of the metal pin still in the plastic will stick slightly to the magnet and help keep it aligned.
you need very little glue, don't put too much on there because it will just ooze down the sides.
use a metal surface so the magnet will not move, preferably a flat horizontal surface.
the polarity of the magnets does not matter.
