Drill Bit Holder




So I bought a big drill press today and to test it out I decided to make a holder for all of my drill bits. The construction is 3 foot long 2x4s stacked with a slight offset. I added a 'foot' on the back side to make the little half pyramid stable.

The hardest part of the whole project is drilling the holes. I used a test block to set up the depth and size on the drill bit. I also used a scrap piece of 2x4 to line up the holes from the side of the 2x4. A fan placed to blow the sawdust off of the drill press kept me drilling instead of always worrying about sawdust messing up the alignment.








Then I drilled holes... a lot of them... of different sizes and depths to match the bits I have.






















I think the end product turned out nice.

Power Supply and Accessories for Teaching about Electricity




I followed the directions from this instructables how-to for "Convert an ATX Power Supply Into a Regular DC Power Supply". It was a good project to let me remember how to solder. Here's the final product:

To let this be a bit more useful for experiments to teach my daughters about electricity, I also built some jumper connectors and a light bulb fixture.

The jumper wires were made from leftover wires from the power supply and parts from Radio Shack:




The light bulb fixture is a low voltage patio lighting bulb wired up to a couple of nails on a wooden block.



The end result should allow my daughters and I experiment with what is a conductor and what is an insulator.

As noted in the original instructable, there are some dangerous components in this project. Repeat at your own risk.
