Hello Peoples, I have a question about my Jointer tables. It’s a G.I. 225hc m1 . After I s4s a 2 1/2’ square post thats 35” long I went back to fix one that wasnt square to the adjacent side. When doing so I noticed that the jointer was tapering the board from back to front?. In other words it was getting thinner at the end of the cut. My technique is good so its not that . Is it because the outfeed table is higher at the far end or is it because its lower at the far end. I forget sometimes and this is one of those times. Thanks for the help.

-- Ive cut this board three times and its still too short?

If the rear table is to high the material will be tapered.
If the rear table is to low the material will get snipe.

or it can be user error, if your not putting enough pressure on the work piece as you go through the cutter head, the work piece will loose more material at the end

The type of taper you refer to would lead me to think that the back end of your outfeed table is high. You said that your technique is good, so this sounds like the infeed/outfeed tables are no longer coplaner. If your jointer uses dovetails ways, and a gib, and you frequently adjust the hight of your infeed table, these parts will ware and you should check if your infeed and outfeed table are in the same plane.
