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

Looks like a neat solution. Interesting drilling set up in picture 5.

Looks like a work of art! Sure you want to get it dusty?

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.
