Adding Body contacts to toys

Body contacts can make the simplest of bends sound really cool. But adding the contact points to a pitch resistor of a toy may be a mystery to some circuit benders. There are two ways to add these contacts to the casing of a toy. One is documented in the Gijs’ nice tutorial depicting the process of using a hot soldering iron to heat and melt the nail all the way through the eye never to less, of a plastic elephant. The Geij’s webpage calls for “chair nails”, however those can also be called “tacks”, “upholstery nails”, or ” furniture nails”. Sometimes the caps on these nails may need to be sanded because they are covered by clear coat paint, which would impede the contact with the skin. That is one way to get the job done, but I often prefer a less dangerous method of using small drill bit to make a hole of same diameter as the nail. Then with a dab of glue to the underside of the cap the contact is secured. This later drilling method eliminates any possibility of burns, unless you were use your finger to hold the contact in place while soldering the wire to it. As well as keeping the soldering end of the mail clean from toxic plastic which may hinder soldering and create nasty fumes. I guess it all boils down to what tools you have available for the project. Thanks to Karl for sending this link.
