Better Bandsaw Dust collection spot?

[benush26]

I was watching Doug Reid's resawing video http://www.youtube.com/watch?v=19KUOXat ... el&list=UL and at about the 3 minute mark it shows the dust collection port on the lower left position of the case.

My bandsaw is old enough that it does not have a built in port so I was going to fabricate one and until I saw this video was going to place it under the table like existing covers.

Could someone tell me why the port (clearly an add on) is now lower left? Logic would say that the closer to the table opening the better chance of sucking in the dust, but the add on is, I presume, by SS so is that where they suggest mounting it?

Thanks for any insights!

My band saw dust port is located below the table close to where the blade would be cutting wood. It was located by the factory in that location when I purchased the saw from Shopsmith several years ago. It does a good job, I often blow or vacuum small amounts of wood dust from inside the case. Jim

I used a toilet flange for the port and stuck it as low as I could and in the middle (left and right) of the cover. It sucks up a lot but not nearly all.

I asked doug the same thing via email - here is what he said:

"I started cutting a second dust collection port for my bandsaw years ago, just to increase the efficiency. Then a couple of years ago in some magazine I read that, from a physics point of view that the best place is the lower left. Works great, especially using two hoses at once. In the video, using the second hose was getting in my way for shooting..."

My old bandsaw, non shopsmith, has the dust port come out of the lower left. I was never happy with the dust collection nor with how much dust collected inside the housing. I added a dust port right below the table as close to where the cutting takes place as I could. I run two hoses and this has improved the situation.

When I got my used shopsmith band saw it did not have a dust port. I added one much like I did with my other saw. If you care to see how I did that start looking at post #48 in this thread:

What I have found is that I still get sawdust coming out the open bottom of the saw. So things are not perfect but controlled enough for me at this time.

Many thanks to everyone for their solutions.

Before reading damagi's explanation from Doug, I began wondering about having two ports. I have the DC and with that amount of suction I figure there will be no problem with two ports. Now I'm convinced it's a good idea. Even thinking about fabricating brushes to gently sweep the tires on the back side, so the lower left might help more.

Thanks again,

Why not brush at the point of blade contact with the lower wheel just below the table('point of cutting')(near the oem port)?

Certainly worth investigating. My unscientific first thoughts were to brush the tires such that the dust would fall towards the lower back dust collection opening and let the initial opening by the table be considered sufficient for what comes off the blade. By brushing the upper wheel, gravity would aid in removal and if the brush was skewed where it touched the tire (though attached in a fashion perpendicular to the case), there would be a better chance of the dust moving off rather than just accumulating on the brush.

I guess if the brushes were soft enough as to not interfere with the tire, they could be multiple places.

Thanks for making my brain do some more mental calisthenics!:eek:
