Thien Cyclone Separator Lid Discussion / Replacing plastic bag with cloth bag.
« Last post by bigfoot on January 23, 2017, 08:08:41 PM »
I am using a 1hp Chiwanese DC, the cloth bag is pretty rough, maybe 30microns up. I just ordered a 5 micron to replace it. My separator is working good, I have not measured the fines though, but hardly any goes into the plastic bag.

My question, is it ok to just replace the platic bag with cloth also?  Would airflow be improved, though its just a 1hp?

Thien Cyclone Separator Lid Discussion / Separator with Planer
« Last post by mrelms on January 20, 2017, 09:56:59 AM »
OK I made a collector from a metal garbage can with a wood "circle" under the lid and it works really well, but I wanted to use the plastic separator and bought one and installed it on the lid of the garbage can, now more than half on the shavings  go into my shop vac I was wondering are my shavings too large for the small seperator has anyone had this problem or could it be that there maybe an air leak causing this, thank you

double height will give better seperation but will hurt cfm a tiny amount

I'm planning on building a top hat Thien baffle. The only thing I have not decided yet is whether to build a double top hat or a "normal" top hat separator.

I'm going to use 6" ducting throughout  my system. I will probably use the 44 gallon Brute trashcan (or perhaps the 32 gallon one).

So, the diameter of the baffle is either 24" or 21.9" (not sure if that's the inside or outside diameter of the trashcan).
I'm making a transition (in sheet metal) to go from 6" to 8" x 3.5". This means the minimum internal height of my baffle will be 8".

So, the internal height for a double height baffle would be 16" (2H of square duct), or 12" (2H of 6" round duct). Not sure how I should count.

I will vent outside. So I'm not after 99.9% separation. I'd rather get more CFM's than perfect separation, as the small amount of dust that makes it through the separator, will blow away in the wind, once outside.

Does the 2H top hat promise better separation or better throughput? I've been reading loads of threads, but I'm still not sure if I should go for the 2H build or not.

Hi, My name is Tom and I was surfing the net looking for info on dust collectors and ran across this site. WOW! much info to digest and then build one. Thanks all for the info and experiences.

Hi,

I'm Staffan. I've ordered a 3 hp dust fan that I plan to use in my new dust extractor system. All pipes and hoses will be 6". I'm making a new dust hood (in sheet metal) for my planer/thicknesser to accept a 6" hose. I will use no filters. The dusty air will vent outside.

This should probably have been posted as a new thread, but I'm not able to create a new thread. Probably because I'm a new user on this forum.

I'm planning a build of the cyclone, but have had trouble locating a suitable trashcan. I've found no suitable trashcans in locally.

I had been thinking of using an empty oil barrel. But I guess those are a bit too heavy to move around for emptying.

I've now found the Brute trashcan online. As many people seem to use this trashcan, I have a question for you.

Can someone who has either the 55 gallon or 44 gallon version please measure the outside diameter of the trashcan?

I ask because I need to know the outside dimensions before ordering. I need to make sure it is smaller than the door opening to the room where my dust collector is.

I found the following info on the web, but it doesn't say if the measurements are taken on the inside or the outside:
55 gal  208.2 L
Diameter:   26.4 in     67.0 cm
Height:     33.2 in     84.3 cm
   
44 gal  166.6 L
Diameter:   24.0 in     61.0 cm
Height:     31.5 in     80.0 cm
                               
32 gal  121.1 L
Diameter:   21.9 in     55.7 cm
Height:     27.8 in     70.5 cm

The largest one will probably not fit through the door opening.  I hope the 44 gallon one will fit.

I'll build a 6" separator. I think both the 32, 44 and 55 gallon trashcans are large enough for this. I read, somewhere, that the minimum diameter should be inlet size * 3. For me that would be 6" * 3 = 18". All of the trashcans are larger than this (assuming the measurements are the inside diameters).
