Trying to find a solution to my clogging dust chute on my Delta
jointer JT360. I connect a 6hp shop vacuum to the 4" port using a
reducer with a 2½ hose connected. This works fine for the first
couple of passes, taking about 1/16" off each pass, then the chute
clogs up and the in feed table gets covered quickly with wood
shavings. I'm jointing kiln dried ¾ pine.
Another important detail is that its winter here and its wicked cold
making the air dry and causing static build up on everything. Not
sure if this contributes to the problem, but I prefer to give all
details in hopes of a good solution in return.
There has to be a solution to this problem. H E L P !
Thanks Tom, will try less taking passes less than 1/16
What does puzzle me is why is there a preset for 1/8" if 1/16" is
considered huge. I figured that taking half of what the preset is I
should be fine.

You're welcome. Well, my jointer manual (PM54A)sez not to take more than 1/64th
when face jointing, so I've gotta eyeball it 'tween the 32ds. I'm betting that
the "preset" you're talking about is not an actual stop or detente, but simply
a measurement mark on the indicator. It's there more for when you get into
rabbeting and such. > Daniel

I have the same jointer and have it hooked up to my 6.5hp shop vac by
attaching a 4" - 2.5" reducer to the 4" outlet with duct tape (didn't have
any spare 4" hose at the time) and the nozzle for my shop vac fits directly
into the 2.5" port of the adapter. I also put some duct tape at the bottom
of the chute to close up the leaks and keep chips from falling out the
bottom. I haven't had any clogging, but I didn't like how the chute
extends below the outlet for the dust hole.
Shopvac doesn't have the airflow capacity to handle this
Dispite the claimed "6hp", it actually has something like a 1.25hp
motor and moves less air than you want. Good vacumm cleaner for the
shop, terrible as a DustColletor

Sure it does. I did this with a 6" jointer for quite a while before I
put in central dust collection. With ONE tool and a short hose, the
vac did fine, with the exception of keeping up with wide boards on a
Chances are, there isn't a smooth flowing path into the hose, or the
1/16" cut is creating so many chips at once, the reducer is causing
the problem. Check the path and try lighter cuts.
Are you sure the vac is getting everything in the first couple of
passes? Before I had my jointer hooked up to a DC I could make several
passes before the shavings would finally back up to the point where
they'd come out of the top. It sounds like the same thing that is
happening to you which leads me to believe you aren't really getting the
shavings in the first few passes. Try a pass or two then with a small
stick reach up through the dust port and I'll bet you can fish some
shavings out that your vac didn't get.
Here's another thought: Depending on how rough your wood is as you make
successive passes your jointer is going to remove more material. This
could overwhelm your vac whereas your vac can keep up with the first
pass or two. I still lean towards my first suggestion.

Some time ago when I was having the same problem someone on the wRec
suggested just taking off the vac attachment to open the discharge throat
fully and let the chips fall in a box. Jointer "dust" is coarse stuff, even
when taking 64ths, and this does not result in any significant floating
sawdust, but the clogging problem disappeared forever. It was a really
effective solution to a big nuisance.
Thank you all for your help on this one, will be trying out some of
the recommendations this weekend.
Also I'm aware that the 6hp vacuum is over rated but I must say that
this Ridgid vac does a pretty good job compared to my 3hp Shopvac. I
must warn anyone entering my shop with a wig to be cautious...

I have a grizzleguts 8" joiner and have used a 4" hose connected to the 4"
square outlet. I also have the two HP grizzelguts DC unit and use 4" piping
That being said I still get clogs on my joiner as you do, to reduce these I
have sealed all orifices with thje exception of the throat, duct tape and
shop rage at the infeed and outfeed table adjustments. I believe the biggest
problem now is the transition from square to round . So now I am going to
get a piece of AC ducting that gives me a smooth transition from round to
smooth and I do believe this will solve the problem.....mjh
