I have a Delta 22-560 that is over 20 years old and only been used a very few times over the years. It looks new and everything is OK except that it will not feed. The problem is the in-feed roller. It looks alright and is clean of resin, but it seems slick and very solid. I can't remember if the rollers are supposed to feel like erasers or are supposed to be very hard. If the latter, I can try adjusting the height. What I do know is that the knives are fine. I have tested pushing a small section of board through with another board and the machine planes it properly. My biggest problem is that (if the rollers are bad -most logical situation) Delta stopped producing rollers for this planer a long time ago, and all the planner parts sites to not have any. Is there anyone out there who can suggest any remedy to this situation? I would really hate to give up on a very nice looking 12 1/2" planer because one part is shot.
