Ummm…. cute? For the Hello Kitty fan who has everything?
Yeah, we’re really not sure what’s going on here. It’s an art piece on which [Denis] spent a lot of time. He polished it, etched it, painted it, applied gold leaf, and drilled a hole for a charm. It’s that hole which interested us the most. He had a heck of a time figuring out how to make a hole in the hardened steel. The solution that finally worked was to use electrolysis to bore through the metal (translated).
[Denis] first made a small depression where he wanted the hole. This took time, and pretty much ate through the engraver bit he was using. But it was just enough to hold a drop of saline. He connected the positive side of his power supply to the ax head, then dipped the negative lead into the drop of saline. Each time the drop turned black he wiped it away and replaced it with fresh solution. Just five hours of this and a pack or two of cotton swabs and he was through.
