After cleaning it up as good as I could I I tried to use it to plane some 4" wide maple boards. It made a he$$ of a racket and bogged down in the slowest setting. I had checked the knives and they look to be in good shape and were just installed before loaning it out. I pulled the belt guard off and the upper pulley had been installed without a key in the keyway (not me!) so it is toast. I think the shaft is fine. I am also going to need to replace the outfeed roller. I see that Shopsmith still has the upgraded pulley set and it says the pulleys are steel. I ordered a set back when I got the planer used several years ago. Those are the ones on it now and they are aluminum.
I need a manual for this thing an any pointers that you may have on replacing the roller. I also need a knife setting jig. I had one at one time but it is probably buried in the black obis.
This is the out feed roller. It looks pretty straight forward to replace.
