The Delta 36-725 is a good saw, and (knock on wood) I haven't had any of the alignment issues many have spoken of. However it has some shortcomings with respects to dust collection. It is equipped with a blade shroud and 2.5" dust port which for the most part does a good job, but a lot of dust gets past the shroud and drops out the bottom.

So I went to work fabricating a bottom for the machine with a 4" dust port. This is what I came up with:

I used a magnetic duct cover to cover the space left by the removal of the 2.5" dust port.
I added a 4" dust port to the frame below.

Here I fabricated the bottom and incorporated a 4" port from Harbor Freight.

Here is a shot of the pluming under the dust collection pan.

After running some scrap wood through the saw there was virtually no dust on the floor.
It ain't a pretty solution but it got the job done.

I went the easy way on my Delta 36-725, i bought it used without shroud and the hose connecting tube, ordered the tube thinking i had the shroud but it was miising too.
I went to Harbour Freight and bought the canvas Table Saw Dust Bag (item # 45794 $ 5.99) that fitted perfectly under the table and covered all the openings with cardboard and duct tape, problem solved, when the bag fills 1/4 i can vacuum it out or i can remove the bag and empty it out. (It comes with easy to place snaps)

Can you go into detail on how you mounted the router table? I am about to do the same with my bosch router table so any help is much appreciated!

Thanks,

I just noticed… is that a Craftsman router top you added? I added my Craftsman router top to the side. I m starting to see a psychic connection.

I made a more funnel shaped box to get closer to the motor and to direct the dust towards the vacuum hose.

Do you happen to have any details or posts on how you added this router table to the saw? I also have this Bosch router table and want to do this exact same thing on the left side. I would love to see some additional photos and some info on how you made it work.

My router table is a Craftsman and is cast aluminum so there is a lip with holes, so I drilled holes in saw's sheet metal extension to match and connected to extension with bolts. The supports are made from ABS drain pipe and I used screw fittings with screw collars on the ends up at the bottom side of the router table to adjust the pipe length to level the router top. The legs are a slip in fit with no mechanical fasteners to hold in place. Hope that makes sense. I put it on the left because I wanted the added length to support longer boards.

For those of you that inclosed your saw and added bottom dust ports, have you had any motor issues. I did the same with my saw, and I suspect that being a vented motor, the dust has gotten inside and stopped it from working. I am taking the motor to a shop and will have more details later, but wanted ask if you have seen any issues.

I bought my Delta locally off of Craigslist, the seller did not have the original legs, so I built a cabinet with a drawer underneath. Changing out the 2 1/2" dust port and removing the factory shroud, I opted to make "ramps" on all four sides along the bottom and then put a 4" port out the back. I just have one shot of that right now, this is looking from the back with the rear cover removed. I used regular gray duct tape to attach to the metal sides of the saw, and foil tape along the bottom to cut down on friction of the dust movement. I also installed a cut pool noodle along the top edges where the sides meet the top, and then some more noodle fit into the slot on the front where the handle moves when tilting the blade. After reattaching the rear panel, I finished buttoning it up with some more foil tape along the outside edges and where the port attaches.

Well, seven years after this was posted, I finally joined the club. I pretty much used nkawtg's method with a flat bottom and a manufacturer dust funnel. I used pool noodles and hot water pipe insulator foam to seal up the larger cracks, magnetic vinyl for the front and back panel cutouts, aluminum tape where I could, but I didn't want to use that for sealing up the edges of the back panel because the stuff is so tenacious; if I ever want to take the back off, this will make it a lot less messy.

I still have a couple of air leaks where a small pile of fine dust settles, but over all, it makes a world of difference!

I did leave the shroud in place. I did disconnect the old blue plastic dust port and just let it hang loose inside. So far that seems to be fine.

I know that it is still going to build up inside, especially around the edges and corners, but I'm OK with that.

Can't speak to the above. But I've done something far less complex with my 725T2. I use the rear dust port with a small Wen DC. And run a shop vac to an over the blade chute that I designed and 3d printed. With that combo I get very little sawdust. I also have a custom ZCI that I designed and printed as well. Which includes some vent holes that further aid in air flow for dust collection.
