Dewalt 735 dust collection...

[jhood]

I'm thinking of getting a Dust Deputy with a 35 gal drum and use it for dust collection on my Dewalt 735 (also for my benchtop jointer and bandsaw...)  Anyone have any experience with a setup like that...?  Wondering mostly about the blower from the 735 and chips getting through to the bag on the CT26 that I have...  I know the CT26 has a lot of suction, and I've seen many videos and posts that the DD collects virtually all of the debris, but first hand comments would be great... 

Thanks,

JH

I have a DW735 with Byrd head hooked to an 1100CFM dust collector through 4" PVC and a 35 gallon homebrew Thein baffle separator.  The setup works well but when working a big project that 35 gallon separator can fill up pretty quickly.  As to the flowrate balance I have not been able to find a spec on the flowrate of the exhaust blower in the DW735 but it pushes a fair amount of air...not sure if it would pressure feed the CT26 but maybe.

Not having experience with the setup I can't say for sure but I do have the DeWalt planer in question and from what I understand, the DeWalt blower produces roughly 400CFM.

The setup should work fine in theory, you probably don't even need to run the vacuum to get it working, people just hook bags to their DeWalt and it collects fine there.

[eek]  I think you'll be severely disappointed trying to use a CT26 (or any shop vac) to collect shavings from a planer.

Even with a 2 1/2"  - 50mm hose the airflow from the CT just isn't strong or fast enough to keep up with a planer.

The built-in fan for the planer is not good enough by itself to extract chips for a regular planing session. A dust collector, not a vacuum type, is needed if you want proper extraction on a long-term basis and have many boards to plane.

There are several examples on YouTube that show it should be fine with the built in blower. Loads of videos on the topic.

Here's one that shows a setup going to a dust right bag from Rockler.

I agree with [member=67935]xedos[/member]  I keep my CT 26 (w/cyclone) parked next to the bench for the sanding/smaller power tools, and bit the bullet by purchasing an Oneida mini gorilla w/5" hose for the DeWalt 735 (along with a hose adapter).  The 735 (and other planers) creates too much sawdust, the CT 26 with my current hose wouldn't be able to keep up, and you'd be emptying it a whole lot more often.  I was running into problems before with all the sawdust clogging the dust port because of the vac not being able to clear it, and now that problem is no longer the case.  I'm really happy with the gorilla, and it doesn't take up a lot of floor space in comparison to other stand-alone cyclones of that cfm.

I used the bag from my leaf blower to catch the shavings.  I seldom do a lot of planing at one time so this meets my needs well enough.

It's really a question of whether you need a van or a truck. I had lived using a planer that did not even come with a blower in the old days...everything done outdoors on my lawn.

Now, mine has the blower, but chips were all over the place after a regular session. If yours is a 15-minute job with just a few boards, that might work. Mine is typically two hours long or more. Every time, my bag is filled up, sometimes from scratch, hooked up to a 1.5HP dust collector in addition to the built-in blower in the planer. Still some chips are found on the floor.

Edit: I use the planer with the auto switch. One time, after using the planer for half an hour, I noticed the unusually large amount of chips on the floor. I thought the bag was full. Upon checking, the bag was not full; the auto switch was in the off position, and so the HEPA dust collector did not kick in when the planer was turned on. That was when I realized the difference between relying on the built-in blower and using the dust collector at the same time.

I might not have been clear on my original post...  I am currently using the bag method directly attached to the planer, chips going into a Rockler bag...  problem with that is it is a major pain to empty the bag into a trash bag...  pretty much have to dig the sawdust out by hand...  which kinda negates the whole idea of making things as dust free as possible... 

And I wasn't even thinking of using the CT26 to directly attach to the planer to collect chips...  I'd spend a fortune on bags in one session...  I was thinking of getting one of the Oneida 35 gal drums (which you can put a bag in for easy disposal...) and having one of the small Dust Deputy on top...  then the majority of debris would go into the drum (and from my planing sessions from the projects I have done I might go through 2 bags for a project...) and just using the CT26 for the fine dust that remains...  taking advantage of the great filter on the unit...

This video on YouTube shows him planing and not even having anything attached to the top of the DD....  which makes me think this would work...

[member=57948]ChuckM[/member] I wasn't saying it's the greatest idea ever, it's just definitely possible with the blower alone. I definitely think a full sized DC and bin is an ideal path for a planer. I was just shooting out an answer to the OPs original question.

I have a 735/Shelix combination that is connected to a Jet Vortex dust extractor. I don't even bother turning on the Jet as the Dewalt produces enough air flow to inflate the bag and deposit everything in the Jet bag.

What makes you think that hose is connected to the barrel ?  The video does not clearly show that it is.

You do understand how a cyclone works , yes ?  The 735 has blower, which is not going to create the "cyclone" effect by pushing the air.  DeWalt designed it to blow material away from the machine and into a bag - not to power a separator.

You can see dust moving through the cyclone.
Cyclone works regardless whether you suck out or pump in the air. Pressure difference is the only thing that matters. Few things to consider here. The drum is under positive pressure in this configuration. The cyclone shown is probably a bit narrow for optimal performance. It is designed for vacs with higher static pressure. I would still put some kind of filter on the top of cyclone. I bet a lot of fine dust shoots out of there.

A similar separator concept:

Interesting thread. The DW735 has been on my list as my entry to planing for a while now. I'd start out with the bag and upgrade to something more permanent later on. On a similar note I think Grizzly makes a decent 6" benchtop jointer G0725 with its own blower as well. For someone like me without a DC system those two options are appealing to get going.

I've had a DW735 and the DeWalt stand for many years now. I built a receiver box into the stand that the planer pumps chips into. This lets me work without have a bag or trash can to drag around with the planer, it's all contained within the stand so does not take up any additional space. I can use it stand alone or connect to my dust collection system in the shop.

In that configuration the planer sends the chips into the box and the dust collector sucks them out on to the cyclone separator where they get dumped into a drum. When working stand alone the box on the stand has flap-style vents in the top that will open to relieve pressure from the DW735's chip ejector. Those same flaps close (by negative pressure in the box and gravity) when the dust collector is connected.

It's worked well for many years. I think I built it around 2009. I know it was before I got the Unisaw and that was early 2010.

I've been meaning to remake the whole box and build it into the stand as opposed to he current box which sits inside the stand, but somehow I never get around to it.

Very clever [member=60461]Bob D.[/member] I like your solution!

Thanks, it's kinda clunky but it works for me and my limited space. One day I'll make a better one.
