I have posted several threads that have detailed dust collector testing and along with effects of ducts and hoses. I borrowed the test equipment to do this as it is not cheap especially the digital thermal anemometer. Now that I have the performance curve for my system, I can use a simple homemade manometer to determine the static pressure and read from the graph for my system the approximate flow. As I read the comments and questions, it would be really nice if there were an easier way...
There are many threads about dust collectors and modifications made to them. Unfortunately, there is relatively little information on the actual dust collector performance and the effect of the modifications. I did some measurements using some expensive instruments that most people will not have access to. There has to be an easier way of checking the performance. The easiest way is to use a manometer to measure the static pressure of the system. You can make your own manometer cheaply,...
Several months ago, I purchased the Super Dust Gorilla 5 HP from Oneida. The specifications on the Super Dust Gorilla were:• 5 HP US made Baldor motor – 19.5 Amps• Backward Inclined Cast Aluminum Impeller – 15”• Max Performance 1860 CFM at 2.5” SP• 8” Inlet• HEPA MERV 16+ Filter• Filter 110 sq. ft I posted a couple of days ago the measured performance curve for this dust collector. That was all fine and somewhat interesting. But, the important part is not the performanc...

I used a great set of tools loaned to me from another...
Several months ago, I purchased a new dust collector. Before, I had a Jet 1.5 HP dust collector with a cartridge filter and vortex cone. It did an OK job and was piped into my shop with 4” PVC. My measurements of the flow at the dust collector were 670 CFM at the 6” port and only 450 CFM at the 4” port with a maximum static pressure was 10.25”. I wanted to get a cyclone style and looked at the ClearVue and the Oneida. While ClearVue makes a very good cyclone, they do not provide a comp...
With the updated system, I needed 6” blast gates for my shop. I was not very happy with the metals ones and the price of them. So, like others, I decided to make my own. For the gates, I would need to have one side be able to mate to the SDR35 6” wyes that I was using so this required a securely fitting the 6” pipe. In addition, I needed to be able to make accurate slide parts and various inlet parts. To do this, I made several templates which were sized to produce ...
I have recently started upgrading my shop dust collection from a 1.5 HP Jet to a Oneida Super Dust Gorilla. The old system was piped with 4” PVC but this was not adequate for the new cyclone system. Looking at the various options, I went with 6” SDR35 PVC piping and fittings. Fortunately, I have a Menards which stocks both the 6” pipe and the fittings. My dust collector is in my garage and then piped into my shop across the ceiling. I did not like the metal strap han...
After hours (no make that days) of trolling Pinterest looking for ideas for my Dust Deputy I came up with this design. My main goal was to eliminate as many 90 degree turns between the cyclone and the shop-vac.
After modifying my Harbor Freight dust collector, I needed a filter for the discharge of the blower. The dust collector mod did a great job eliminating a majority of the dust, but it was still discharging fine dust into my workspace – something I didn’t want to be breathing. This time I drew up a plan in Sketchup and used it to guide me in this build. The build was rather straightforward, and a made small changes here and there where it made sense. I call it a 3-stage filter b...
Modified Harbor Freight Dust Collector I made this before I started creating videos for YouTube. This is my interpretation of the Thein Baffle reconfiguration of a Harbor Freight dust collector. I did this for a couple of reasons: First, my shop is tiny, so I needed to fit the dust collector into a smaller footprint. Second, I wanted an easier way to empty my dust collector. Third, I had future plans for this collector to practically make it 100% efficient. Feel free to comment or...
