Chris Donnelly, an engineering technician and machine shop manager at the U.S. Army Engineer Research and Development Center’s (ERDC) Cold Regions Research and Engineering Laboratory (CRREL), reviews a design made for a machine he designed and made in CRREL’s machine shop. The machine shop is a one-stop-shop for ERDC researchers, scientists and engineers who need a unique part made, which cannot be bought off-the-shelf, and is designed and fabricated by Donnelly.
