Having some issues with my new 60HH Jointer specifically dust collection !!
And I am having trouble trying to determine if there is a faulty issue with my machine or do these Helical Heads throw more dust then the system can handle.

My dust collection is either a porter cable 650 cfm or the one I have hooked to it as of now is a grizzly 2hp 1550 cfm
with 10 feet of hose to the collector !

I have taped the voids where the table meets the cabinet with insulation tape !

Stock 4’’ outlet

The problem is on the right side(under the inffeed table) where the table adjustment lever is as you look up into that area there is a small 1.5×2 inch opening where the dust is shooting out !!

Anyone with this same machine experiencing this symptom ??? The machine cuts a glass finish but the dust blow by unacceptable since I just dust proofed my shop !! Air filtration system ,Kapex crosscut saw etc…..

The only time my jointer spits out anything from other than the DC chute is when there is a clog somewhere.

I have the 60 HH. Most of my dust makes it to the DC but it does throw a little out the infeed side. I’m connected to a Powermatic 1.75 hp DC that sits immediately next to the machine through just a few feet of pipe. I would doubt your 650 CFM unit is up to the task but the HF should be able to handle it.

I don’t think taping the voids where the machine mounts to the base will do anything. I have not noticed a large opening near the adjustment handle but I’ll look next time I’m in the shop.

I have a hard time collecting everything my jointer produces as well. It is an 8” with helical head, and I modified the dust port to 6” with a 3HP collector and the airflow doesn’t seem to have much effect on where the chips fly.

The in-feed side of the table still gets sprayed with chips as i finish my cut. I do not know what can be done to improve this. Possibly using a sacrificial piece following the workpiece? May be safety concerns here when you are holding the sacrificial piece and stopping the machine.

Do you both have this same Jointer 60HH Helical head ?

Keep in mind that i have only made about 20 passes and there is nothing clogging the dust collection side it is empty of any shavings! There is just a small flow of dust coming out of the area I mentioned.

Also I just thought of this is there any chance my infeed and out feed were installed incorrectly by the factory as in reversed—so that my infeed is actually the out feed—-I need to look at the configuration closly to see if this is possible.

I just can’t believe the machine was designed this way there has to be a glitch

Are other woodworkers just allowing this and moving on !!

interresting so when the board starts clearing the cutterhead the vacuum is greatly decreased and allows dust to come out the back hmmmmm

I believe mine is consistent through out !

Check out my vid and see what you all think please only if you have this exact machine TY

Also here is a pic of problem area

Yes same jointer, 60HH. Don’t expect that you will get 100% dust collection from any machine, but it does appear you have more escaping than I do.

It is highly unlikely that your tables were installed backwards. But it you want to verify, the front edge of the outfeed table has a rabbetting groove in it. Look at the picture on the PM website.

Oh, and PLEASE use push blocks and read up on safe jointer use before you run another piece of wood across that machine. Your short video scared the bejeezus out of me. You will be happier if you keep all your fingers.

I watched the video and thats unacceptable. You gonna need more cfm.
I also don’t see the need for push blocks looks your handling the wood just fine.

Also in reply to Tung Oil

That is a exercise Powermactic suggested !!! the tapeing of voids where case meets cast iron table !!!

AJ2 any suggestion on a brand and HP rating as well as com ??

The hose connected presently usually goes to 15’’ PM planer and is 2 HP 1500 com !!! dedicated and 10-12’ of hose
i was told the plastic ribbed hose cause 30% loss which would only take my cfm down to 1050 still above what PM told me was minumum 800 cfm.

I bet the plastic hose is dogging your air flow. I use it for the short connections only! from my main pipes that looks like this stuff.

Can you run 6 inch from the collectors main branch? That will help a lot if you can.

Here’s about what I get with mine

I bet you have something stuck in there. Mine is not the same, but very similar design and it does what yours is doing when it gets a clog. The first time it happened was right at first use, when somehow I pushed a piece of masking tape or whatever it was protecting the cutter during shipping down there and didn’t realize it. Those ear muffs with music are a bad idea….cant hear your DC, or not.

The second time was after I ran it with the DC hose connected, but the DC not turned on. Both times it was a real bear to clean out. Had to reach up the exhaust port and pull all the crap out, then now air in where ever I could at the top. Machine unplugged of course.

Sleepinginatree,

I have the PM PJ-882HH 8” jointer. It looks similar to the PM 60HH 8” jointer; at least where gaps and voids that frustrate good dust collection exist. When I first received mine, I too had a leaky machine. I found debris was being thrown onto the infeed table from the gaps around the fence assembly. There may have been debris originating from under the infeed table but I do not recall. Since packing the open cavities with upholsterers’ foam, almost all of the jointer generated debris is collected. I have no debris being thrown from under the infeed table.

The small and large voids around the table/cabinet, table/casting ends, and around the fence were packed with upholsterers’ foam. The foam was cut a little oversized for a good friction fit and packed into the voids. Holes cut in the foam allow the foam to slip over bolts of the fence assembly and thus hold the end pieces of foam in place. The pieces on top of the fence assembly are unattached. I used ½” thick foam to seal around the fence support assembly/fence connection and 1-1/2” thick foam elsewhere including the large gap under the infeed table.

I also packed foam between the table saw table and the cabinet. This effort seems to have helped a little with table saw dust collection.

The upholsterers’ foam can be found at an upholstery supply store such as JoAnne’s Fabrics. I found the easiest way to cut thicker upholsterers’ foam is with an electric carving knife; the ½” thick foam cuts easily with a pair of sharp scissors. As can be seen in the photo, masking tape is a poor choice for attaching one piece of foam to another. Unfortunately I do not have a better foam to foam attaching solution.

Underside of the Infeed Table…

Fence Assembly with photo taken from outfeed end of jointer….

Standard corrugated dust collection flex hoses increases static pressure and thus reduce air flow. One reference I consulted states that a standard flex hose can add an additional 50% of static pressure over that of metal pipe. Smooth walled flex hose should reduce the flex hose’s contribution to static pressure and thus increase air flow.

Today I face and edge joined ~25 boards. Thinking about your post I cleaned off the jointer beds and floor before I started to see how much mess mine makes. Here’s what it looked like after I was done.

My infeed bed has some dust on it but the floor is as clean as when I started.
