Delta 14" Dust collection again

[John Powers]

I got the little dust attachment in the mail. Really pitiful. I'm sticking with my latest rube goldberg job. Saws 25 years old and I can't cut the lower door. I'm a wimp. So I got a Veritas Magnetic Dust Shute. Pricy at $30.00 and you won't need the magents or reducer. I cut with my Dremmel the side with the magnets opposite the label so picture a three sided plastic box tapering to a hose connection that accepts the shop vac. I just got the little Dust Deputy. Went for the whole thing as bying the DYI kit just left too much to cobble together. Anyway the modified dust shute is stuck up under the table which is molded to exactly accept it. Big rubberband between the table knobs, stick the hose in and we're sucking some dust. Not 100% but a big improvement. I guess I have a big shop vac but the Dust Deputy seems to magnify the power. or maybe its just that I can see the sawdust whirling around. the Dust Shute is stuck right up at the source which is not the case with the pitiful little plastic thing which only has a 1" hose connection. I'm assuming the tables are standard which may be a big assumption.

John, a vacuum cleaner isn't going to move enough air. What brand of saw do you have? I made a DC for my 14" Delta that connects to my central DC system, using 4" pipe. No cutting involved, just add a couple brackets to support the DC system. Wood magazine currently owns the rights to it, so I can't show it here. Hopefully they will publish it soon.

14" Delta. I'm in a different league in my garage. But I must disagree that the large shop vac is not up to the task. That thing just pulled 300 Gallons out of my basement in no time. If it can fill a 10 gallon tank with water in about 40 seconds it can produce negative air in a bandsaw. I'm surprised with the results I've gotten. I'm a great believer in a big strong shop vac.

John,

The other thing you might want to consider is adding a couple of brushes to clean the blade and wheel. A lot of a bandsaw's mess are chips carried all the way over the top wheel and down onto the table. A couple of strategically placed 99 cent brushes which are screwed to the frame will stop most of it.

[John Powers]

yes, brushes are in place. Another low tech thing that helps. this is a metal/wood saw with the gearbox. reminds me of a tank I used to drive.

You are confusing static pressure, like that provided by a shopvac, and CFM (with a little SP on the side) like provided by a true dust collector. A common mistake. Static pressure will suck the chrome off a trailer hitch but won't suck a ping pong ball up from 2" away.

You need CFM because you are drawing air from many directions not just from directly in front of the 1.5+" or so diameter opening of the hose. Here is the explanation in simple terms- blow a cloud of cigarette smoke then try to suck it back up- can't be done. That is why you need CFM.

Cut a round hole in the lower door with a jigsaw with a metal-cutting blade and screw/tape/glue a plastic 4" dust port over it.

You'll get over it fast and be thrilled that you did it! I know I am (picture of my saw attached). I'm not sure I would recommend using a shop-vac, however. I use a 1-1/2HP Delta with 1-micron felt bag and it works great.

Alan, I managed office buildings and mechanical upgrade projects for 30 years. Crawled through more duct than I care to remember. CFM, SP, dampers, laminer flow, turning vanes I see them in my sleep. I'm talking about one saw, collection about 1 inch from the blade. The saw is virtually dustless now. Now if I hit the lottery and build the dream shop on the bank of a trout stream I'll spare no expense as I provide dust collection for my Italian made 18" Bandsaw. I was really addressing the that recurring agonizing decision about cutting a hole in a 25 year old bandsaw or jury rigging up something else. My dream is to have a system that has at least 3 "blast gates"....love that expression.

No holes, no permanent mods.

Attach some angle iron to the front and back of the table using existing fence rail bolts. Angle iron supports a slide-in/slide out ply frame. Attach a sheet metal shroud to the ply frame. It should envelop everything under the table and connect to a 6" DC hose- picks up EVERYTHING.

I made up a box of 1/4" ply, duct-tape, a blast gate, some magnets, and it attaches to the under-table webbing (as long as at 90 degrees).

The smaller hose connects to:

mounted between the saw and the stand. Newer saws may not have this 'port' at the bottom.

Anyway, it works quite well. The Mt Vesuvius cloud of sawdust that used to emanate from the backside of the saw has pretty much been eliminated.

I forgot add this pic to my last post- with my pickup I can tilt the table:

:p ;)

I'm telling you, the rules and methodologies should be universal.
