Using 4" hose, with a 90 right on the outlet of the planer.

Diameter is the same as a rubbermaid brute 20gal trash can.

Thanks!
That's about the size I was thinking about making mine. I used some kerf-Board that's used for concrete forms to make the cylinder, I was just unsure of the inlet & out sizes. Mine will also sit on top of a metal 20gal. trash can.

I have had a push through thien top hat in operation on a 735 planer for almost 10 years.  Works great, doesn't clog,

Thanks for the reply!

Quote from: bbain on July 01, 2023, 01:28:02 PMDon't over think it.

Where's the fun in that. ;D

What's your top hat's diameter & what size hose are you using from the 735 to the Thien Baffle.

Quote from: jgt1942 on June 14, 2023, 07:57:21 PMI plan to use a 5HP motor with a 16" impeller.

I don't think I have ever seen a Thien Baffle used with a motor larger than 3HP, most of the conversions I've seen use the Harbor Freight 2HP blower/motor.

This old post has some PDF links that may help you figure out what the diameter of the baffle should be.

Here's another old post of a 6" inlet build.

Quote from: jgt1942 on June 14, 2023, 07:57:21 PMit will be necessary for me to build a housing for the motor and impeller as well as the tophat.

From what I understand that can be a little tricky since the motor's HP / Impeller / & Housing are normally designed as one unit. I'm sure there's some type of mathematical formula to figure it all out, but the biggest thing to watch out for is the motor drawing too many amps.

Doug

QuoteThe question I have for you is what type of waste will the DeWalt DW735X planer create. If you are using the long knives it will produce long strings and often the strings will block the circular cutout.

I've read that the impeller in the blower of the DeWalt 735 will somewhat chop-up the long strings?

For now, I'll just be using the straight knifes but I do plan to upgrade to the helix-style head at some point.
I'm also thinking about making the circular cutout slightly wider which I understand lowers the efficiency, but it should help with the clogs.   

The majority of my planning will on narrow width boards so the strings should be minimal length.

I guess I'm going to have to figure this one out myself!

I would guess that no one here has tried that exact set-up, so nobody wanted to give you an answer.

I just found an old post here on the same topic after doing another search. It's about 4 years old, but I brought it back up to see if I get any response.

Doug

I realize that this post is almost 4 years old, but I'm looking to try to build something like this for my newly acquired DeWalt 735 planer.

If the original poster is still watching the forums, how's it been working & have you done any upgrades?

Here's a link to my post.  https://www.jpthien.com/smf/index.php?topic=1444.msg8601#new

Well 50 views over 3-weeks & no replies ???

Does it make any difference if the dust/air is blown into the Thien baffle vs being pulled through it like a normal set-up?

I recently picked up a DeWalt DW735X planer & it has a built-in chip exhaust system that blows the chips out of a port on the rear of the machine. The planer comes with an adapter to connect it to a 4" hose, using a hand-held anemometer I'm getting about 225CFM of air flow out of the 4' port.

I've seen several YouTube videos of people with the same type of planer using a trash can style Thien baffle to collect the chips with just a small filter bag on the outlet.

Would a top hat style Thien baffle work with just the 225CFM from the planner?

I had originally planned on buying and modifying a HF dust collector for the purpose,

If you were planning to modify a HF dust collector anyway, You could check to see if a replacement blower impeller will fit the fume extractor's housing?

Also double check the motors rpm! Some fume extractor's may only use a 1725 rpm motor since the static pressure doesn't need to be much.

I have a Cincinnati 2HP 200S & I'm currently in the process of upgrading it.
I'm still trying to decide between building a Thien Baffle or just adding a Cyclone to the system?

Here's a few pictures of my Cincinnati's blower section & impeller in-case you wan't to compare the two. The original impeller is 12-1/4" & given the blower housing's design, There's not much room to add a larger impeller.

Just curious what everyone has used to seal up the pvc without going too permanent?

I've used the marine & plumbers line of GOOP for sealing non-pressure joints in PVC before. It can be scraped off with a razor blade if needed

Doug

QuoteI can assure you I don't watch my separator during machining operations.

Sorry if you misunderstood my comment about watching the dust collector, I didn't mean to insinuate that you did!
I was referring to myself as being easily distracted by trying to watch the separator during other operations.

As a kid it took me several years to figure out if that light inside the refrigerator actually ever went out or not  ::)

QuoteThere are probably a number of ways to clog up a dust collection system, and I found one of them.

I hadn't thought about a clog!
I imagine that it's not really that hard to do, And things can probably go bad quickly.

With the solid sides it would probably help out to at-least add a couple viewing windows to the top cover.

Doug

QuoteIt looks like you have all the basic components to build a very workable dust collection system.

I'm sure I will add & change things as I go, But I figure it's a good starting point!

QuoteThe spec's all seem acceptable, but how adequate the blower is will depend on the plumbing, i.e., how long, what size, how many bends, how much flex, etc.

I'm still working the details out on that since space is an issue!
Really my only stationary item is a radial arm saw with a customized T-track table top that I use all the time! All of my other equipment is on wheels & is moved around as needed. The dust collector will be located in the corner of my garage & for now I'm just figuring on running a 6" dia. X 12 foot long metal main line along the wall of the garage.
One combination 4" & 1-1/2" outlet with a blast gate will be used for the RAS & I'll probably only need one additional 4"  outlet with a blast gate & about 8 feet of flex hose to connect equipment as needed.

QuotePersonally, I was never crazy about the kerfed separator wall method.  It just seemed like a lot of work to cut all those kerfs, and then have to line it with laminate

Yeah I agree that cutting all those kerfs would be a lot of extra work!
But in my case the kerfed material was given to me for free so I figured I would give it a try.

QuoteAnd of course solid walls do not allow you to see what is going on inside your separator.

I can see where seeing inside could be helpful when first setting everything up!
But after it's all set-up, I don't think I would really wan't to be watching my dust collector while running a piece of equipment.

Doug

Here's a couple of pictures of the filters I'm going to use, I got them for $25 each from a machinery surplus store.

Doug

Here's some more pictures of my blower unit disassembled, The impeller is aluminum & if I remember correctly it's a little over 12" dia.

Doug

Hello I'm new to the forum & looking for basic information & any tips or suggestions on building my first Thien style separator. I've read a lot of threads here & on other forums & I've watched a bunch of videos on building the Thien style separators.

Here's the items I've gathered together so far for the build!
1st is a Cincinnati 200S barrel style dust collector, Here's a pdf link with the specs.
https://www.cincinnatifan.com/catalogs/DustCollectors108-sls.pdf
 
For the filters I picked up 3 surplus canister filters! I originally only planed to use one filter with the set-up & keep the other two for back-ups, But I may decide to go with dual filters if using one filter creates too much of an exhaust restriction? Here's the specs. on the filters.

https://www.industrialcartridgefilters.com/MANUALS_TECH_DATA/Tech%20Data%20Sheet%201565954.pdf

For my collection can I'm using a heavy duty 32 gallon galvanized metal trash can.

As for the construction of the unit, I'm pretty much going to try & follow the information on this old thread by "pitbull"http://www.jpthien.com/smf/index.php?topic=429.msg2187#msg2187 I noticed that "pitbull" hasn't posted since Oct. of 2014! But his method of using the kerf-cut plywood is basically how I'm making mine.

In my case I got some pre-cut kerf material from a friend that was left overs from a cement forming project. The material is about 9-3/8" wide & about 7 foot long so I should have more than enough for the project! Probably enough for a another smaller unit made for my shop-vac, Provided I don't mess-up on the first attempt.  ;D
