I had an unused dust port from a drill press table kit. I narrowed the port’s wide mouth with wooden blocks and attached it to the underside of the bandsaw with 1” rare magnets. A Y-connector is used to hook up the bandsaw’s built-in dust port and the shop-made dust port to the 1-hp dust collector.

09A01.86 – band clamps
03J6093 is the product # for the Y-connector from Lee Valley Tools that also carries various types of connectors.

I am curious on how this improved the dust collection?

During cutting, saw dust generated has two ways to escape: into the saw chamber (50% – 60%?) and into the air via the gap between the saw and chamber (40%?). The built-in dust port allows the dust inside the cover (99%?) to be collected by the dust collector (1 hp), while the shop-made dust port is seen capturing most of the dust before it can escape into the air. Overall efficiency, I’d rate it 90% or more.

The dust that doesn’t go under the table is collected by a box fan, if the stock is not too long. (partly seen in one of the pictures posted).

I will check my bandsaw for clearance as the bottom extraction port does not really clear dust effectively.
This is regardless of me retrofitting additional baffles to direct the dust into the port, which incedently is mounted above the floor of the saw enclosure, a smilar location to your saw, go figure?

Hi Rob,

Do you use a dust collector or a shop vac? A d.c. (1hp) delivers 700 – 800 cfm vs 150 – 180 cfm from a shop vac. Place your hand or fingers in front of your added-on port to see if you can feel any suction. Please see the quick test I did for my upgrade below. Chuck

I inserted a black card board under the bandsaw to collect the dust particles that couldn’t be extracted by the shop-made dust port

and cut a few pieces

And the result?

Finally, I added a wooden block to support the y-connector on the stand (recessed holes drilled on the bottom of the wooden block for two 1” dia. rare earth magnets)

Chuck, you dont actually show the line coming out of the saw.

I cannot see the “box Fan” you speak of

My Setup

I have a shop vac, its a noisy screamer so I use my DC set up outside on the tools.
I should measure the Air flow some how but the noise levels produced by each machine is the decider.
Its OK for chips, sawdust and shavings but my drum sander fine residue still chokes the bags regardless of the intermediate trap

Here it is Rough as, built five years ago…... hey…... but it works well

My mod to prevent getting Zapped from static build up.

-- Regards Robert

Nice set up, that should work well.

Hi Rob,

The second & fourth pictures of the first set of pictures shows the dust shroud and the port without the hose attached. The port is hooked up to the narrow hose ((1-1/2” dia.?) which goes to the Y-connector.

On the second pic of the second set (added photos), you can see the box fan (more accurately, the filter that is attached to the box fan) on the right side.

The power hook-up is like this: When the bandsaw is turned on, the box fan and the light are powered on automatically (via an auto switch). The d.c. can be turned on manually or thru a remote switch.

If you use a d.c. (usually 700 – 1200 cfm for a 1 hp unit), you should be able to feel a strong suction at the shroud. Unless the shroud is too wide and far away from the blade with a huge gap, most of the dust should be captured.
