It cuts nice and straight, but the in-feed table is as far up as it’ll go, and it’s is still taking too much of a bite. I can’t even bring the table to reach the ‘zero’ mark for depth. .

Thoughts?

hand wheel. I’ll take a measurement when I get home. I know i can’t get it to take light passes, like 1/16th of an inch.

Sounds like the knives aren’t down far enough.

I second Fred. The knives need to be adjusted.

Can you adjust the infeed and outfeed tables into the same plane by using a long straightedge? If so, then the knives are set improperly. If not, then something is messed up with the adjusting mechanism.

Have you reached the end of the “0” on the depth of cut scale or is it just short of the 0? There is a lock out knob that will allow you to crank it up to the 0 on the depth of cut scale. At least there is on my Jet.

Some Jet jointers have preset detent knob that needs to be pulled out while adjusting. Look for a little black knob on the back of the infeed table. Give it a pull while adjusting the infeed height. I think the first detent is at 1/16” so that may be where your stuck.

Paul’s got it. Back the height adjustment down a little for a DEEPER cut, then release the black knob. It’s kind of like shifting into reverse when you parked on a steep hill. You gotta roll forward before you can get into reverse. The knob is actually supposed to set the maximum depth of cut at 1/8”, but I think the mechanism is stuck.

You might want to check the bed alignment on infeed and outfeed now that you have figured out the problem. A little excessive adjustment with that black knob engaged can throw it out of alignment. Don’t ask me how I know this!
