DIY Dust Collection System

Post by mjohn » Tue Feb 26, 2013 8:18 pm

Dust collection is a good thing to have, the purpose is to collect most of the dust in a separate container so that you don't clog your vacuum filter as easily. A clogged vacuum filter will decrease suction and strain your motor.

Here's mine. All parts available from your local home improvement store.

Parts list
5 Gallon Bucket with a lip (I like the translucent one, I can monitor dust levels)
Screw top lid (brand we have is 'Leaktite')
PVC Elbow (I used a 1 1/2" one with threads on one side)
PVC Extension (I used a 1 1/2" one with threads on one side)
Extra length of hose, I use a ShopVac which fits perfectly over the PVC. Take a small cut section of your hose to your hardware store to test.

Hole saw (or a steady hand and an exacto knife)
Epoxy/Plastic Glue

How's it work?
What you're doing is cutting a hole in the center of the lid and then again on the very edge. The lid snaps on and gives you threads and a screw-top lid to prevent you from having to crack open the bucket every time you want to open it. The center PVC pipe is going to point straight down. It's not very long. This part is getting attached to the Vacuum. On the edge you're going to insert the 90° elbow with it pointing along the edge of the bucket. This feeds to your dust shoe or nozzle at your workbench.

When the vacuum is on, it will vacuum up dust and debris which will enter the bucket and swirl around the edge of the bucket and fall. While some lighter dust will make its' way to the filter, the majority of dust and debris will collect in the bottom of the bucket. It'll swirl around happily. When you get a few inches or after a job, pull off your hoses, unscrew the lid and dump it. Eventually the sides of the bucket get a little weakened and if something blocks the dust the sides of the bucket will pop in a bit. Be aware of it! They'll straighten back out when you're done. If it bothers you, get a steel bracket to put on the inside of the bucket to keep the sides from caving in.

Nice. I have a 55 gallon drum that is setup like this for my wood shop dust collector.

These work great, I'll probably have to build one for my ShapeOko.

What I want to know John is where did you get that FANTASTIC label on your bucket "I HAS A BUKKIT!" That is great. I want several. Do you know where that can be gotten?

I am currently working on modifying the Harbor Freight 97869 model which is the one you are speaking of I believe. It was about $155 on sale with 20% off after taxes.

It was a great deal...although, I think you need to consider it incomplete when you first get it. I am adding the Wynn Environmental 35A cartridge filter (http://www.wynnenv.com/35A_series_cartridge_kit.htm) to it and also making a cheap modification of the Thien BaffleThat purple monster of Vaughn's is a Harbor Freight 97869 https://thehomedweller.com/best-dust-collectors/ he has painted up. He has gotten excellent results allowing him to go weeks without even touching the filter, and when he does have to, he just shakes it or blows it with air externally to make sure the fines are not caking up on the inside which he says is so minimal he could go longer without touching it even.

The 35A filter is safer (.5-1 micron depending on the one you choose) and will increase your CFM capacity a bit over the 5 micron bag that the unit comes with originally. You may want to consider changing out the bag on your jet as well since 30 micron is not so good.

According to everyone I have talked to and everything I have read, these machines are the best bang for your buck when coupled with the cartridge filter (less than $350 together depending on discounts, taxes and the filters shipping cost). This is a FAR FAR CRY from the $$$$ you will have to fudge out for a name brand DC with a cartridge filter already installed or with an aftermarket addition. Especially when you consider the HF model has been getting so many great long term reviews. The 97869 is an upgraded version of the previous model with larger impeller, 5 micron top bag (30 micron was on the old one) and clear bottom bag...otherwise the same for the most part. The older version with modifications such as I am doing, is still getting good reviews years later.

Here is a video of Vaughn's again, the first time around with a collar that he removes the second time around so there is no need to worry about what the collar is. Look at that cyclone action with nothing dropping out of the filter the second time around: http://workingwoods.com/misc%20image...lar%20Test.wmv

Should be perfect for your shop as I consider it more than enough for mine at 288 sq. ft.
