Topic tags/keywords: jointer problems

hi, i just bought a 6 1/8 jointer/ planer, craftsman, 1975, and am having trouble getting it to work right. the out feed table is not flat, i can put a straight edge on it and slide a piece of paper (thickness .003) back and forth untill i get to about 3” of each end. the owners manual says to adjust the knives so they are .003 above the outfeed table. the jointer pal knife setting jig i bought says they should be flush with the table. the infeed table is not flat either. i get a barely wavy edge like a real flat sine wave on the wood, and the last 1/2 to 1 inch of the wood is cut slightly deeper than the rest of the board. it seems like the wood is following the not flat outfeed table up and down as i pass it along. how flat should the tables be? what is the correct setting for the knives?

On most joiners I’ve ever seen or used they are flush. as far as the flatness of the tables goes a machine shop might be able to mill them flat for you, depending on how much that cost it might be cheaper to get another jointer

How bad is the wave on the outfeed? It shouldn’t consistantly cause an issue across the length of the board if it is the cause of an issue.

A dip would cause the end to dip down causing less of a cut, then lift up causing more cut than before then even out. Even waves would even out across the highs as the board went across them.

The sine wave tells me the knives are not set even and only 1 is cutting, or your feed rate is way too fast. I get that on mine when I do a fast feed.

there’s no wave on the outfeed. it’s high on both ends.

Have your say...
