What does a non cut or ground magnet rod look like?
Using for example an Alnico 5 rod magnet that s uncut usually starts in lengths between 6.5 and 11.5 inches long. It has a rough surface and made by larger mills. After the rod stock is ready for shipping and sent to many smaller job shops that surface grind the rod magnet to the proper diameter and cut to the desired length. Early Fender magnets were cut to the desired length and many were not surface ground as the raw magnet stock was cast close to the desired diameter. The surface grinding is done to help get rid of pits, fissures and other chips and imperfections. The newer magnets are cast a little larger to help give a better surface appearance when surface ground. The majority of all Alnico rod magnets are sand cast or sintered.
