Topic tags/keywords: stad thicknesser dw735 planer dust filtering

Howdy everyone,

LJ already has several DW735 station projects: for instance,
- a compact stand by BrandonGonzales
- a stand with a built-in cyclone by AdrianM
- a cabinet with outfeed tables and AC filter by Matt in Franklin
- a cabinet with outfeed tables and AC filter by Kelly

Wanting to start building mine but still wavering with some design decisions and wonder if some sharper minds could share some thoughts, especially about chip collection.

Ingredients
At this stage I know I will use:
- thick ply, also possibly some 3×2 douglas
- the same flex hose as on Brian's stand
- a flange to screw that hose into a lid or table
- the same 4” casters as on my table saw stand

Chip Collection into Sealed Bin?
My main question mark right now is chip collection. With the powerful blower in the DW735, everyone is saying that there is no need to hook up an extractor. For that reason, my guess is that a cyclone may not be needed either.

Rather than drawers or compartments that need to be vacuumed, the simplest for me would be a bin that I can tip into a garbage bag. Because of the power of the blower, the lid will have to be on tight, and there needs to be a path for air to escape. I’ll probably have to make a ply lid to attach the flange. Not sure what kind of filter to use for the outgoing air.

Your Thoughts
Here are questions on which I’d love to hear other people’s thoughts:
- Choice of vessel. Metal garbage bin? Plastic bin that lets me see the level of chips? A twist-top would probably be inconvenient if a flange with the hose is screwed into the lid.
- Mounting an air escape on the vessel. How would you do this? On top? On the sides?
- How would you filter the escaping air? Sourcing components in New Zealand is tricky so ideally it is effective and easy to find.
- Any other ideas that pop into your mind when looking at the other designs.

Huge thanks in advance for any thoughts you can spare.

Here, this was built for a drum sander with a blower, but it may work for the 735.

I wouldn’t limit yourself to searching for a 735 only planer stand/station.

Here’s mine for my ridged. I can hook it up to the shop vac in the cart if I’m doing light work planing or to my real DC if I’m doing alot of planing.

Am I correct to say you don’t have the planer yet? If you do you would already know how much will collect from planning a few boards. It doesn’t take long to fill up a drum.

I have my DW734 piped to a dust collector by way of a Thein separator in a thirty gallon drum.
I am cramped for space so I built a small footprint roll around stand with storage underneath for hoses. I need all the storage I can get.

I use mine with Dust Deputy cyclone similar to the second link by Adrian M,the difference is,I just put the DD(with the attaced lid) on a garbage can.works well.

Thanks alot for your ideas, guys!
Wow, seeing new things on these designs that I hadn’t considered: tool storage, Thien, looking at designs for stands for other planers etc…

One thing I’m not understanding: since the planer is blowing and the chip container won’t be attached to a DC, does a cyclone or Thien still serve a purpose? For instance, does it significantly lengthen the life of the filter by the exhaust?

Speaking of filters, I see that Bill used a cylindrical filter. Any tips on which filters are lung-friendly + cheap + convenient to attach for that kind of job?

When I first got my DW735 I tried to make the dust/chip collector from a CARDBOARD box! THAT was a big failure. I ended up using a big garbage can and it works quite well. You can see what I did here … (scroll down thru the post and the “after” pics are down there

Manuka, that wasn’t my project, but when he made it I suggested that it might also work for his 735 because I knew it had a similar blower and that his separator may work for that too. I believe it’s working for him. I don’t think the planer is going to make very much small dust and therefore wouldn’t clog the filter.

@JoeinGa, that cardboard box setup was creative. Playing with the idea of using a rubbish bin, thank you.

Regarding filters, not getting clarity on what would allow sufficient airflow while blocking the fine dust. Reading the Bill Pentz dust safety pages at the moment and feeling a bit paranoid…

This is making me consider another option: ducting the blower’s output through the wall, right into an alley that leads to the garden, to get the chips and dust right out of the workshop. Not sure I want to commit to making a hole in the wall though. :)

If you can, ducting outside will save you a hunk of change, improve performance (no restrictions), and save a lot of time that otherwise would be spent cleaning a filter. I would still suggest a Thein Cyclone to remove the big stuff before venting.

Here is a link to my dust collection cart for some ideas.

Most of us are using the Wynn Environmental Cartridge Filters. They are over 99.9% effective down to 0.5 microns. They also improve flow due to the design.

When I planed the rough poplar to make the drawer stock for our kitchen remodel, I emptied my 30 gal. drum four times. That would be a lot out in your alley. :-)

You didn’t answer my question. I asked if you have the planer and have used it?

Manuka,,the idea of drilling a hole in the wall of your shop to blow the dust from the planer out is ,impractical to say the least,a drum full of dust is a common sight after planing just a few 6’ boards,you are not sanding lightly ,you are taking off 1/16” of each board with each pass .

Hi timbertailor, MTStringer and distrbd
Thank you for helping straighten my thinking about venting outside.
With the amount of chips produced, it really sounds like I’d really need a Thien separator or a cyclone before venting the remaining dust outside!

As it happens I have a small cyclone from eastcaroga that I’m currently making a cart for to use with a shopvac. Might just find the right connectors to give it a try.
@timbertailor your dust cart is inspiring. I’m at the early stage of thinking through chip and dust collecting options as well as venting and cleaning.

@MT_Stringer I’ve had the planer for a few weeks and haven’t yet fired it up. Waiting for ducting fixtures as finding stuff locally in New Zealand is quite challenging. Taking the planer outside is not easy on a sloping driveway although I could carry it onto sawhorses. But your pictures clearly shows just how much chips get produced.

Yes sir. It can produce a lot of chips. My first effort at dust collection was a shop vac and a dust deputy. It could make two or three passes with some cedar fence boards, then have to empty the 5 gallon bucket the dust deputy was mounted on. That got tiresome in a hurry.

I still use the shop vac/ Dust deputy with the miter saw and random orbital sander. Practically everything goes into the bucket. I check the shop vac frequently but the bag and filter are clean.

You are going to love that planer.

UPDATE: finally built the stand !!! Yay!

Big thanks to all of you, you really helped nudge my thinking along. I took on board the advice of using some kind of separator… And yes, it makes a lot of chips!!!

In the end I decided that instead of storing the dust on the stand itself, I would build a separate cart with a cyclone that I can use with other tools.

Pleased with the result so far, but I realize that I haven’t yet figured out what to do at the outlet of the cyclone. There’s no visible dust coming out, but we all know there must be clouds of harmful invisible dust.
So… What to do? Not loving what I’ve read about filters indoors. At the moment, wondering if I should hook up a dust extractor and vent outside. Any input appreciated. :)

Have your say...
