I must admit my first attempt at a acceptable dust port for my Grizzly G0555 failed. It still left opening for dust to escape and I trashed it. I had to cut a lot of particle board in circles and thoroughly dusted the shop. That stopped me after that project and I wanted to collect the dust RIGHT OFF THE BLADE before it got to the lower port on the saw and everywhere else. So the following is what I came up with and it worked well after feeding 4 feet of particle board through it for a test.
I needed something that would not harm the blade if it hit it but that could be put right up in the business area and removed quickly for blade changes. One of my favorite materials is PVC pipe and it was round like the opening in the saw table.
In order to connect a hose to the port I needed it to come out to the side so I started by cutting a piece of 2” PVC pile on the miter saw at 30 degrees. It had to clear the blade and the three guide wheels so I carefully laid out the position of the blade if this pipe was all the way to the top, and also laid out the centers of the wheels on the side of the pipe. I used a Forstner bit to cut the hole clearances for the wheels and used the bandsaw to cut the blade clearance slot. I use the existing 8-32 tapped holes from the previous attempt to mount a holding bloc for the port. To secure the pipe to the block I used a part of a 2” PVC coupler and turned the inside to just slip over the pipe and I screwed a piece of black plastic to it. Once I had all the alignment complete, I locked the ring on the pipe with a screw. I used another coupler on the end of the pipe for the port to receive the hose. for that I glued in a short piece of 2” pipe and turned a 1.5 degree taper in it to a diameter of 2.300” at the outer end. Then you can plug any 2” vacuum hose into it.
For this attempt I have a bigger vacuum I call R2D2. I found him on the curb when I was going for a walk around the neighborhood. Someone threw it out and it works just fine. It is now dedicated to the saw and I have an outlet that comes on with the saw so it is always left in the ON position.
