   you are plugged up below the cutterhead, when it's off..poke down there with a thin rip scrap, with the suction on.

   Many thanks to you and the others that confirmed the internal stoppage.  What an incredibly simple solution.  I was surprised by two things as I worked on it.  First was the relatively small amount of chips it had taken to virtually block it.  The second was that when I lowered the infeed table to it's max to get the best view, I saw that the cast iron 'throat' was terribly irregular.  It almost had a 'broken' configuration across the width of the unit (ranging from about 1/4" to a shy 3/8".  That casting is undercut below, and it would take little effort to straighten it to a uniform 3/8".  Do you (or anyone else who reads this see a problem with doing so?

   I have a Ryobi AH-112 combo planer 12.5" and a 6.25" jointer with a 6' bed and extension roller actually a very good machine..It had a casting similar to the Delta's under side like you describe . This machine is now 15 yrs. old, when I first got it I used die grinder to smooth the chip passage and since have rarely plugged it up..might work for you. If it does clog it is from facing wide stock and less than perfectly seasoned material, combined with a heavier cut than I should be taking..so , with that said I would tweak yours if it does not require TOO much dis assembly. I would not remove the either table unless you are prepared to readjust and re align the whole thing, to me that is impracticle, maybe watch what you are doing to cause a clog.

   Thanks again!  I believe - though I haven't tried it - that with the infeed table in it's lowest position and the cutterhead well-protected, I could do a fair job of smoothing that casting with a file.  Might take a bit of elbow grease, though.

   I agree with Sphere. With the machine unplugged you can also reach up into the inside of the machine through the dist port (or remove it) and be sure the entire inside of the unit is clear of all dust and chips.

   Cheers,

   I had the same problems with my DJ20 8" jointer.  And they are right, there are chips blocking the path from the cutters.

   I would take my 4" hose off regularly and push a stick up there to clean out the chips.

   One other thing I did was remove the outside cover skirt of the jointer and fit a piece of flashing around the dust shoot to ensure any suction from the dust collector was forced up to the cutters.  I used duct tape to tape off all the seams.

   Now I collect about 90% of the chips.  If I see chips on the jointing surface, I can bet the outlet is plugged again.

   Delta does have a problem with this and probably will not fix it any time soon.
