My last post covered the importance of enthusiasts in keeping technology alive. For many of us the “crazy bug” came from wandering through Radio Sh...

Many years ago, when asked how the five-meter gear was checked, the quality manager responded, “When they’re that big, they’re never bad!” That may have been the attitude and practice in the past, but it no longer serves the manufacturer nor the customer. Requirements have been evolving steadily, requiring gears to perform better and last longer.

NASA is now 3-D-printing spare parts up at the ISS (International Space Station). And in zero-gravity environments. And some of these parts are small gears and actuators, for starters. Every indication is that the list of power transmission-type parts to be converted will soon grow.

[starbox] A few years ago I presented a paper on reverse engineering at the AGMA Fall Technical Meeting. I heard through the grapevine that some f...
