Unwanted bows in a jointer

I have a Delta benchtop jointer as well, and I’ve found that 50 inches is too long. There just isn’t enough consistent support to get a good edge. I haven’t had reliable results with anything over 36 inches.

Thanks for the advice. I kind of had a feeling that this was the case :(

There was a thread the other day about this problem. They said if you carefully set up a roller stand on each end of your jointer you can joint boards of any length.

Thats a great idea! I have been meaning to get some of those for other uses too. The only problem I have is that basement/workshop is very uneven. It is an old dirt basement that the previous owners had bricked and then very hastily covered with a very thin layer of cement. I think I could find a good place for it with some shims and a careful setup.

check your outfeed table ,
if it is not dead on with the cutterhead ,
it wont cut absolutely flat .
to high , and the wood is crowned in the middle ,
to low , and it is bowed in the middle

I have the same machine. As patron said the first thing to check is the cutters even with the outfeed. I aligned mine with a dial indicator and get very good joints. If the board is longer than thirty inches or so be sure to keep constant pressure (on infeed and outfeed) while feeding.
