I bought a small dust separator. I almost bought the Dust Deputy but this had everything and was cheaper.
It’s essentially a 5 gal bucket with the hoses and clamps and works on the same premise as the Deputy.
I also bought a new Rigid shop vac.
The only tool I hooked this up to is my planer.
While there is a decent amount in the bucket, nearly half of the saw dust went into the vacuum.

My thoughts- vacuum is too strong?
This contraption simply doesn’t work.
Or am I missing something in setting up this unit?
There were no instructions included and seemed pretty straightforward.

Is it the Dewalt 735? That planer has a blower that may overwhelm a small cyclone.

Do you have a pic? I have seen another setup where the hoses on the inlet and outlet were inadvertently switched. Is this a hand planer? Otherwise I doubt you will have much success with a vac keeping up with a full size planer (so no your vac is definitely not too strong).

Hope this helps. Hope you can post a pic.

It’s the dewalt 734.
Could be backwards? I have the elbow piece connected to the planer, is that incorrect? Even though that’s embarrassing I hope that’s the problem.

I believe the elbow should be on the outside whole (closest to the edge of the bucket) with the elbow tangent to the side of the bucket. That creates the cyclone effect. The center then gets connected to the vac. This type of separation is OK but nothing like a dust deputy or Thien baffle. As Pintodeluxe and I said you have too much planer for you vac.

Hope that helps. Let us know if switching the elbow and hoses helps your situation.

Look how this one is set up:

If the lid seal isn’t good I think it can
cause a lot of chips to get into the vacuum.

Ok I’ll make the switch!
So the Deputy would be more efficient in this situation you think?

The DD is more efficient than this type of separator but it looks like this has slightly larger ports so would less likely to clogs. Your biggest issue is that you reduced the 4” planer port to fit a vac with too little airflow to keep up. The volume of debris passing through either system will be your biggest challenge.

Let us know how it is working with the elbow switched.

Makes sense, thank you for the insight!

I switched them and is much more efficient, though I’m going to need to keep an eye on the vacuum as debris is still getting in the filter.

Those lid separators don’t hold a candle to a dust deputy. I speak from experience.

Glad it helped. Part of the problem with the type of separator you have is as the 5 gallon bucket fills past half way the new debris starts blowing around the old debris already in the bucket and up the vac chute it goes. That is because the separation and the debris are in the same bucket. The DD does the separating above the bucket so you can fill it higher. With a planer your bucket will fill pretty fast. A larger bucket would help that situation.

Check out the Thien separator (A diy approach to your separator).
