Thanks to Andy, Al, Beth, John, Laurie, Len, Marty, and Scott who volunteered for a demonstration at Whitehall High School.
Jeremy Shaeffer invited our group in to mold some 3d printed patterns his engineering class made themselves. They did a really good job. We were joined by one of our previous FiB coordinators and past president of our local American Foundry Association Jim Perrault.
