I've been cutting light gauge metal sheet with a 24” DI-ACRO O’NEIL-Irwin shear for about 30 years. Cuts are no longer clean. The shear has been used a few times a year to cut .03 aluminum. Can't afford to have it professionally sharpened. Is there advice/info here on how to go about tuning/adjusting? Thanks!
