Not only can this project help with machining titanium, it’s also a geocache headed for the deepest part of the ocean in the world: Challenger Deep of the Mariana Trench! In addition to this titanium block, we also machine its syntactic foam marker on the Hass UMC-750. What are geocaches and geocaching? Geocaching is basically a worldwide scavenger hunt! Random items a.k.a. geocaches are hidden and tagged with their coordinates often accompanied by puzzles, log books, and codes to “claim” them. There are likely lots of geocaches around you right now! How cool is that!?

Check out the hydroforming die Michael machined on his Tormach 440, designed to work at the bottom of the Mariana Trench:
