band saw saw dust

I have been trying to improve my band saw dust collection and have discovered that saw dust is apparently being pulled by the blade completely around both wheels and is then released just above the upper blade guides and goes all over the table top and from there to the rest of the saw.

My dust collection is just below the blade opening in the table top so do not see how this is is possible.

Does anyone have a solution for this?

What kind of bandsaw do you have? What kind of dust collection are you using? Is the below the table collection port connected to the table, to the lower wheel housing, or just an opening below the table near the blade? More info and pics would help us help you I think.

A blade or wheel brush might help.

I have a similar problem with my 14" Jet. I put brushes on both wheels but it didn't help. I saw an article where a guy used PVC pipe to make a collector under the table that he said really helped....now if I coud just fine the article

I have a Delta 14" band saw, and an older Delta 2-stage dust collector that is a 650 CFM unit. I just installed a 4 " PVC straight tee underneath the table top that came from a reader's shop tip in the July 2010 issue of Wood magazine (I have attached a snapshot of the article - I hope you can see it alright).

I have a brush on my lower wheel and it does not help either. See the response I made, I put a snapshot of the article I used for this dust collection tip.

I am guessing the sawdust is just buzzing right by the collector's port in the gullets of the blade. I think a brush on the inside with the collection port near or just behind the brush may be the solution. The brush needs to knock the dust clear of the gullets to allow it to be sucked into the port. Just my theory. I read that tip too; maybe the guy has a high CFM collector, I don't know. Maybe he should give his drill back. JK.

After seeing that lots of dust collected in the bottom of the housing, I modified the cover to accept a 4" hose located near the bottom. It helps a lot. But, the under table PVC pipe would probably help, too.

Had not exactly thought about putting a brush there, but did wonder about maybe putting a piece of a synthetic "steel wool" under the table insert to see if that helps. But that might not let it get to the dust port. I had noticed that even though the blade is new it looks like it has pitch on it although I have not used it very much.

And I agree with you that the fellow that submitted the tip probably has a larger dust collector. Personally I would like to have a unit like the Jet 1100 CFM.

I think a smaller fitting and maybe a straight or elbow instead of the tee by the blade. ( you loose airflow sucking from the side of a tee) Then add a connection in the bottom of the saw sucking dust from around the bottom wheel. I have a 4" connection there and a 2 1/2 by the blade but they came that way and I have a bigger dust collector. For your set up I would go with a 2 1/2" at both locations.

I reduced the branch of the tee down to a 2" so I could maintain as much CFM as possible. I used to use a 2-1/2" vacuum cleaner connection in the bottom portion of the lower door, but sealed it off when I went with this tee idea. I think I will figure out how to connect them together and see if that works any better.

A simple duct pointed up under the lower guides solved that issue for me: http://www.thewoodnerd.com/workshop/...n.html#bandsaw

I had a vacuum connecting on my band saw similar to the one you put in the back of your band saw (smaller of course) and just today I hooked that up to the tee I placed under the table top and that really took care of most of the saw dust (except what was ON the table top).

I think if I could add something like what you have above your table top would take care of that, but do not think my 650 CFM collector would handle that in addition to the other connections.
