Hi, I am having a problem replacing the blades on an older Craftsman 6 1/8" jointer. I purchased this jointer new around 1983 and have used it occasionally over the years. The model number is 113.206931 and the serial number is 4017.P0663 I never attempted to change the blades until recently and cannot get the wedges loose in order to remove the blades. I have tried WD40, PB Blaster, and a 50/50 solution of automatic transmission fluid and acetone that a friend of mine says works better than anything one can purchase for this purpose. I have worked on this for about a week now with no success at all. It is very hard to hit the wedges with a punch since the bearings are real close to the cutterhead, and there is hardly any room for prying. I have not tried to use any heat and I'm a bit reluctant to do so. I thought that perhaps I could knock the arbor out and then with the cutterhead removed from the jointer, I would be in a better position to deal with it. So, I came across this forum and thought that I may be able to receive some expert assistance and/or advice. I'm not sure how hard it will be to knock the arbor out but Sears does carry replacement bearings if I screw them up but there are no wedges or cutterheads available so I need to proceed with caution. I noticed that on the cutterhead there are two screws which appear perhaps to be set screws for the arbor but i'm not sure about that. I assume that the arbor can be removed with a punch and hammer? Not sure how else it could be done? I'm not terribly excited about removing the cutterhead just to replace blades but not sure what else I can try in order to loosen up the parts. For the time being I can put the screws back in (they all did come loose) and sharpen the blades a bit with a stone. Thanks for any advice. larryn
