Wonders of the net. How clubs are actually made. Forged versus cast. It's fascinating. Then all the stuff that comes afterwards, like lie and loft adjustments, the entourage of golf labs on wheels for the tour, the gadgets used to bend and measure... Gotta figure a way to get inside a factory.
Then there's all the stuff about the balls and how they're made, how they squish when hit, why they spin. As a kid, a balata Titleist ball was a real find. Today, the balls are a bit different as is the kit and technique necessary to make them fly. The super slo mo stuff is awesome. Have to squish it to make it go.
Then there's the magical shafts, and even more magical putters. Can't find much on how titanium driver heads are made. Hmm...
