Project Information

I spent a couple of weekends building this baffle for my dust collection system.

Made from MDF, threaded 10mm stud, 115mm sewerage pipe and 150mm air vent duct for the output hose side. I will hook this up to the 150mm port on the DC rather than use one of the two 100m ports on the plastic spiggot

the Black sewerage pie is 115mm or 4 1/2 " so I had to make an adaptor to fit the 4" hose. I did this by cutting a 4" section off the end of the black pipe and cut a vertical slice on one sideapprox 3mm wide on the bandsaw. You can see the seam in one of the photographs. When you squeeze it back together it fits snuggly inside the 4 1/2" pipe. It held the seam joint and welded it in place using plumbers plastic pipe weld cement, works great.

It is to fit a 200 litre drum so I hope it works ok when I go to set it all up.

Thanks for looking.

David

Thanks for the input fellahs, I tend to overdo things a little but I'd rather do it right first off rather than have to go back and fix it up sometime later…......I hate that.

Welcome to the world of Thein, I've had mine now over a year and it just works amazing. It works so well that the trash can started to collapse in the center so I cut out a wooden ring and sealed it to side of the trash can and now it as quite as a church mouse….enjoy the clean surrounding, nice work on your lid….BC

Great workmanship. I didn't recheck the Thien drawings, but the clocking of your intake pipe doesn't look quite right. If it doesn't work properly, that may be the reason.

David, been busy in the shop I see. It looks a treat, with the finish. I hope you show a pic of the whole setup when you get it hooked up and let us know if your truly happy with its performance.

Black Cherry, how did the ring quiet your set up???

Guys thanks for all the interest and information sharing and of course the kind words.

I'm still a couple of weeks away from installing the whole set up, it has taken a lot longer then I imagined. I had to cut a new whole in my TS over the weekend but that's a different story!

Steve - I figured the Thien was the easier option to build. I figured the cyclone is a project for me in the future, once I have gained the necessary metal working skills. I hope you are right and that it works ok.

Ajoseph, I'm not sure it will work at all but I'm sure a little tweaking will provide me with a reasonable performance. The intake will be about an inch in from the side of the can, what I fouled up on was not rotating the baffle around a few inches. This may or may not affect the performance. If push comes to shove I may have to take it out and rotate it a little to maximise the cyclonic effect before the chips drop into the drum, fingers crossed I won't have to but with all projects some fettling maybe required to get it spot on.

Vrtigo - the pipe was purchased from a plumbers merchants, I since found out that I could have bought galvanised ventilation pipe cheaper and less of an issue with static but I have what I have now. The pipe was cheap but the fittings elbows, branches etc were quite expensive.

Bogeyguy - I have a Jet 2HP dust extractor I bought the additional 0.5 micron drum filter to replace the existiong top bag so all in all I hope to be breathing less dust very soon.

Blackcherry - I will be using a 50 gallon steel drum as a collector, I'm not sure if that will be noisy but it should not give me any issues with collapsing or being crushed from the vacum?

Hi Rick - I thought you might have been casting a few rods on the lakes, hope you are well and looking forward to hearing about your fishing adventures.

NormG - Apart from breathing dust I seem to spend half my shop time with the vac going over everthing if I'm not doing that I have a broom in my hand wihich just seems to spread the dust back onto the surfaces again. My shop photos may jst be an illusion, not as tidy in real life.

Tech - I will defo report back on its effectiveness but anything has to be better than my circumstance now. Fingers crossed I will be able to report back with some good news.

Hi kiefer - It does look a bit odd, when my wife saw it she thought it was for the house and said "I'm not having that in the house" I'm just hoping it lasts a while because I hate having to do things over.

Hi Tom - Thanks again, maybe once I get this dust cxollection thing done I can start making some stuff from real wood. Thanks for the kind words.

Hi Pat - Yep, been kinda busy over the past couple of weekends and a couple of evenings. My shop time is about to come to an end fairly soon, the good lady has projects for the house lined up for me. How did you getr on with the bird house angled roof project?

Thanks again fellahs.

I used a small 35 gallon trash can and the shop vac use to play the can like an accordion, once I install the ring inside the crunching sound subsided into peace bliss…lol. What I would really like to find is a 15 gallon oil can, high gauge steel drum and a lower profile would sit tuck away under my out-feed table. Still looking for one, enjoy your out-fit…BC
