When using the jointer today the wood was vibrating slightly as i sent it across it. Trying to keep pressure down. Where do you want the pressure to be, and how much wood do i want to take off at a time?

You should try to take off about 1/16 th of an inch.

Also, jitter is possibly from the blades being too high. They should be about .001 to .002 over the outfeed table. Much higher will make the board jitter. You will not need too much pressure down if setup correctly.

Pressure should be even.
This will help you a lot!

You want more pressure over the outfeed side as soon as about a foot of your board is over it. In the beginning though, even pressure. Be careful not to tip the piece into the cutter head, especially with smaller pieces.

Good info above. Also, make sure you joint the board concave side down. This is true for face jointing and edge jointing.

surely, is a knife blade issue. could be:
1.) all knives are set too high
2.) 1 knife is higher than the others
3.) you are taking too much off in a single pass. As brian said..1/16th inch.. or even 1/32th depending on the board itself
4.) 1 or more dull blades

Pressure on outfeed after the head. Vibration may be caused by dull knives. Experiencing that at the moment on mine.

Changing the belt to segmented one helps remove vibration.

Thanks for the advice! I will check out the youtube videos, and get the stuff to set it up properly as well as checking the blades

could be dull knives or the knife hone angle is incorrect. should be ~45 degree bevel, if this was reground to a different angle you are getting the heal of the angle hitting. In my experience this results in a smacking of the wood.

Too deep of a cut and dull blades.

Once you make sure blades infeed and outfeed tables are set properly,think of passing the wood across the cutters as presenting the wood to the cutters.If you force down the wood your intended result will be skewed,same thing when edge jointing.It took me a while to get to that point,you will get there also.
