Dust Port on Delta bandsaw

[Thomas Wilson]

I have a hard time cutting into a finished thing even to make an improvement. I overcame my phobia and added a dust port to the bandsaw. Big improvement!

The dust collection on mine is DIY as well. : )

Won the TOP TIP prize in Wood Magazine several years back with my DC port for 14" band saws. No cutting required.

I am not super pleased with mine. Thomas Wilsons looks good as good as OEM. I do not find Bruce Wrenn's on the web right away. Bruce, do you have a link or image?

It is all about air flow. Some of the designs that use a vacuum hose attachment that attaches right below the table achieve a lot of capture with a vacuum cleaner but base of the door need big cfm. I am using a 5hp smart gorilla pro to overcome the inherent limitations of the design.

I cut green wood from time to time and still get build up on the tires even with the vac and dust collector.

From an old SMC thread I see it is in the June 2010 issue, I still do not find it on the web.

6" split into two 4" ports, one I cut into a 1979 Delta 14" band saw, the other attaches with magnets.

My Delta bandsaw has a 1 1/4” vacuum port right below the table. You can see a shadow of it in my original post. I will eventually pipe in a wye to that vacuum port. I doubt it will make much difference. I used to use the vacuum port by itself. It missed a lot of dust.

Thanks guys. I have been hesitant to add a dust port to my new to me bandsaw (1960's Rockwell 19"-20"), need one as it is a dusty mess with the factory setup like Thomas's.
You are convincing me that this is the right way to go, I thought it would be best just had lots of doubts.

If you do do this, don't expect much if it's piped to a DC. At that size port, about the only thing that's going to be effective is some sort of shop vac.

Great tip Bruce!

Dust collection is already excellent. The DC is the variable speed Oneida. It generates 25 inchH2O. That is nearing vacuum level of suction.

That is excellent! Lots of air pulled laterally across the blade. That is bound to work.

Here is another approach that directs vacuum flow directly across the blade immediately below the table.

He uses a vacuum accessory tool that just happens to be the ideal length and shape to be a snorkel reaching in from the side. The inventor cuts a kerf in the side of the nozzle so that the blade passes through it. The top of the nozzle is opened up so that the spray cone of sawdust from the cut enters the nozzle by its own inertia. The tight kerf on the lower side of nozzle acts as a deflector to stop the saw dust particles so that the lateral air flow can draw them into the dust collector. The inventor says that taping up the kerf behind the blade improves collection a great deal. For efficient collection, this hard to beat.

On a closed cabinet like a bandsaw it is all about making sure there is an additional port allowing replacement air in at the same rate as the extracted air.

True but the typical Rockwell/Delta 14" cast iron bandsaw and it's dozens of clones are not anywhere close to being closed cabinet saws. There is no shortage of open areas for replacement air.
