Hi,
Welcome to the total solution to Dust Collection for the Grizzly 17 inch BS. Use the concept to adapt it to your Band Saw.
In the beginning we had the typical BS DC problems. Dust from band saws seems to be more difficult to coral than some of the other machines. Glenn, in his own inquisitive way searched for an answer. He came up with two things that really tamed the beast. I will take you through the path I followed to get to the answer. We hope it will be helpful to you.
First I will show you the result that each of us achieved.
The sawdust you see in the lower wheel cover is the accumulation of a few months with NO CLEANING. Glenn uses his much more than I do. However, his compartment looks just the same.

This is one of two things Glenn did to make the improvement. Basically he did not allow much sawdust to flow down into the lower wheel well. He did this by making a bandsaw Zero Clearance Insert. The insert is basically anything you can do to captivate most of the dust just under the BS table. The DC then whisks the dust on its way to the bag, barrel or whatever your unit has. In this case the ZCI is a thin piece of plywood (1/8”) that goes back to the back wall of the wheel well. It also continues forward to be next to the access door when it is closed.
Notice the two brushes; one wipes the inside of the blade, the other wipes the tire. Also notice the opening with the cross piece in it. That is a port that we don’t even use. In fact mine is not even capped on the outside.

You have to lay down to view this picture unless the Gurus can fix it.
After the blade passes into the lower wheel section and before it goes through the ZCI air is moved past it into a 2.5 inch stay put or flexible duct. This then goes about 12 inches and wyes into the 4 inch BS duct.

This is the second of two things that we did.
Here is how I designed my box that goes just under the table. That’s the black box that you see at the top in picture 3, above.
I started with some nice cardboard cut from a box. I used cheap scissors, paper cutter (not at all necessary), razor knife, ruler and tape (blue stuff in this case, but anything will do). I looked at the pics of Glenn’s and made some estimates. Then I cut out my cardboard pieces and taped them together and, of course, found out that parts of my box banged some pieces of the BS and left gaps other places. Hi there Mr. Murphy.
I stuck tape on to my model where my cuts were too deep and I cut the cardboard where necessary to miss pieces of the BS. Then I made another model which was very close, however, not perfect. Third time was “Charm” so I was ready to go to wood.

This is the beginning of the real thing.

OK two pics to show you the internal bracing for my box. Unless you have the same BS I do, yours will look different. In my case there is a flush 0.75 inch rare earth magnet at each end of the “MAGNETS” sticker. In my case they are what stick to the door of the lower wheel well to hold the box in place. I just pull the box off when I tilt the BS table. Otherwise the tilting table would run into it. The magnets are in the bottom front of the “box” and are stuck to the door. They are just a bit closer together than the two screws you see (for obvious reasons---I like the nice tips on my Forstner bits).

I painted mine flat black so that it would disappear in the shadows under the table. Glenn left his natural wood and used shellac. His looks nicer than mine---But then you knew that even before you read the thread.
Any questions PM me.
Enjoy,
