There was a mill set up with the new 4th axis tombstone at the Tormach Open House. They were making these cool little whistle/bottle opener/keychains with this set-up. We were able to see this in action and it was slick to see them pumping these multi operation pieces out. In a later workshop, I was fortunate to receive one of these keychain's because of a question that I asked about Path Pilot and tollpaths. Thanks to Rogge for tossing one to me during his demo!
