Magnetic Lamp and Tool Holder - Using Microwave Salvage Parts

Featured
There never seems to be enough light in the shop, and when working with a band saw or drill it can be very important to clearly see what you are doing.  I had an old broken lamp hanging around thought it would be good to adapt it to a magnetic base, that would let me stick the light on my tools and shine the light just where I need it.  Here is how:

Step 1: Step 1 - Tools and Materials

  • Sheet metal ( ferrous, you want it to be magnetic ) – mine came from the case of a microwave magnet.  Microwaves are often a source of parts, search the web, instructables, or as a sample see this:  Taking Apart A Microwave by dog digger  http://www.instructables.com/id/Taking-Apart-A-Microwave/
  • Donuts magnets from a microwave oven
  • ¼ inch hardboard or plywood ( mine was salvaged from old flooring )
  • Epoxy
  • Remains of a lamp or other tool to mount
  • Drill
  • Saw to cut the sheet metal and hardboard

Step 2: Step 2 - Prepare the Base

Cut the hardboard so the two magnets can sit next to each other with room for a mounting hole between them.
Then cut one or more pieces of sheet metal to pretty much cover the surface of the hardboard.  I used 2 layers.  This material is to let the magnetic flux “flow easily” from one magnet to the next, this will increase the strength that the base holds on.  Glue up ( with the epoxy) so the metal is on one side the hardboard.  Use clamps and let it harden well.  When the glue has set drill a mounting hole for the lamp between the space for the magnets.
I would be concerned about adding more magnetic fields around that analog meter movement, but if it works for you and there isn't any change in calibration I guess it's OK ...

You are right, the VOM is more of a prop than a useful application, it will probably go onto a less sensitive tool in the shop.

I was looking for a lamp to mount on the side of my computer. LOL

Very good idea! now i know what to do with the broken desk lamps in my shops, got lots of magnetron lying around my shop that i salvage from some microwave i scrapped.
we could also use magnets for broken tv or cassette radio speakers..
thanks for sharing!
