- A box of jumbo size paperclips (this size is made with 1.0 mm diameter wire). - Two small pieces of hardwood. I purchased two hardwood flooring samples at a local building supply for 25 cents each. - A pair of wire cutters and a pair of long nose pliers. I recommend the wide flat kind shown above. If you already have them, a regular pair of needle nose pliers with side cutters also work pretty good. - A couple of 0.8, 1.0 and 1.2 mm drill bits. Harbor Freight has a set of 30 various miniture metric drill bits for just $3.99 - A rotary tool with a cutoff disk to cut one of the drill bits. - A drill for drilling holes in the hardwood. Manual and electric drills both work fine. - A small ruler and a pencil for measuring and marking drill holes
NOTE: Other gauge paperclips can be used. Smaller clips will be easier to bend, but your projects will need to be somewhat smaller because of the reduced wire length. Other size paperclips will also require different size drill bits.
