Brent Delfel is accustomed to an auto shop full of students wanting to learn about diesel engines.
These days, when he shouts instructions his words ricochet off the walls and car parts lining the work space: “Don’t force it! Loosen up the thumb wheel!”
On a late January morning, Delfel was supervising three students as they worked together to adjust a set of truck wheel bearings, a repair he finds rewarding to teach because it requires precision at every step. In this era of COVID-19 restrictions, they were the privileged few allowed into the classroom that day.
