Topic tags/keywords: dust collection ports reducers adapters pipe

After pre-ordering the new Laguna F2 table saw, I decided to upgrade to a real dust collection system as well. I found a used Jet 2 hp dust collector with a Super Dust Deputy cyclone for a great price and now I am trying to learn as much as possible about designing the pipe layout and sizes.

My question: the Super Dust Deputy has a 5” inlet, so I intend to run a 5” main line with branches to each tool. I understand that most tools have a 4” port, so it is easy to install a reducer to attach to the machine, but what about tools with a 1.5” port (table saw overarm collector and miter saw specifically)? I believe the saw might come with a wye in the correct size – I’ll find out when it arrives. For the miter saw, I figured I would install a hood behind the machine with a 5” port, but what about the built-in port? Any advice?

Generally speaking, I think you will be very disappointed with the performance of that DC when you choke it down to 1.5”. DCs aren’t meant to work that way and you will do much better on the small ports with a shop vac. Don’t feel constrained with the port sizes on your tools…if at all possible modify them to be larger. That’s easy on some tools (jointers, for instance) and very hard to do on others (like some of the table saws with internal plumbing to the blade). But in most cases you will be better off with larger ports. As for the miter saw, all I can say is “good luck” with it.

1 1/2 ports are more designed for vac cleaners, higher drop, low flow.

Again, PLEASE, go read everything on the ClearView and Oneida site, then watch the Stumpy videos. I would run a 6 inch trunk for sure.

I am going to try and give my miter one more try with a direct shot 6 inch “big gulp_ to my soon I hope 5 HP ClearView. Not hoking up a hose as the port wil be shooting drectly into the scup. Getting airflow under it may be a challenge.

Let us know how you like the F2. They look nice, but are a hybrid aluminum contractor trunnion on a box. Said to run quite smoothly. A little short blade to front edge so yo may want to make some clamp on extensions.

You can make adapters out of pvc. Sometimes you have to heat it, sometimes not.

I have an older version of the Rockler Quick Change connector, but actually a piece of pvc works better for some things. All 4” connectors are not created equally.

Yes, choking a dust collector down to 1-1/2” beats down the performance of the collector, HOWEVER, I tapped into a Y and added a 1-1/2” hole to allow me to run a 1-1/2” hose under the table of my 17” bandsaw over to the lower rollers.

When the collector port to that bandsaw is open, it pulls from upper and lower 4” dust ports and, now, the 1-1/2” hose.

Before I added the 1-1/2” hose, the lower bearing would be buried in sawdust in just a couple minutes. Now, hours in, the bearings are still free of dust built up around them.

Key here is, I am not just collecting from the 1-1/2” port/hose.

Add to this mix, I made an adapter to allow me to run a 1-1/2” x 20’ hose off the collector. It works, BUT a vacuum stomps all over it in performance (with a shorter hose) for collecting off tools that require smaller hoses. Accordingly, the 1-1/2” hose still hides behind that collector and hasn’t budged for a couple years.

I’m inclined to think a vac, in combination with a lower cabinet 4” hose would work far better, BUT it would be interesting to see how the 1-1/2” off the collector would do.

My over-arm takes a 4” and I’d use it for every tablesaw cut, if it didn’t get in the way of my push shoes.

Thanks everyone for all your help! I decided the way to go is to build a wooden dust shroud around the miter saw connected to the larger pipe, then have the built-in 1.5” port just shoot the dust directly into the shroud so everything gets sucked up by the larger pipe.

Have your say...
