CNC Milling for Students: Create a Pewter Casting

Colorado Teacher Paul Clinton is getting his students involved in manufacturing, Via Make!

Paul Clinton started out 19 years ago as a shop teacher. Now he’s an “engineering technology” educator, a title bestowed on him by his Colorado school district that made a commitment to STEM education 15 years ago. Using his high school’s well-equipped fab lab to give his pupils hands-on learning experiences is his chief goal. But it’s not his only one.
