In my opinion some the open stand 6 inch jointers such as the Delta JT360, Jet JJ-6OS, General International 80-075L, Steelex ST1001, CraftexCT086, King CanadaKC-150, and probably a couple other brands that I may have missed, which all basically have the same type of open stand and dust collection setup where the dust port is directed very close to the floor of the dust chute, more then likely causing some air flow resistance and lowering CFM before it reaches the cutter head area. I feel that the port should be pointed in the direction of the chute's flow to be efficient. I had a JET JJ-6OS, and this is what I came up with for a more efficient dust hood.

What the heck! Why would Jet do that? Your design makes all the sense in the world.

I'd think the Jet design would partially plug pretty quick further restricting flow. 

Jet's discharge appears to be a 4" diameter??? Is your design a 4" or 6" outlet? Hard for me to judge.

I need to fabricate something for my 80's model Craftsman open stand instead of just using a "chip" bin underneath. Of course I need to invest in a DC first, and Oh, somewhere to place it.

Dust collection ports are only an afterthought on most tools these days. Too bad, since it's fairly important (at least to me). Did your mod make a big difference in how well it works (I'm guessing it did)?

@CharlieL 's mod is pretty danged handsome too, nice tin work Charlie.

I used a 4" port.

To be honest with you Fred, I didn't use the jointer much, thats why I no longer own it, but I believe that the hood did make a difference. I don't see how it couldn't of.

It looks like the Jet design was put there just to say dust collection is provided, with no thought about that sharp 90 degree angle. Your design makes a lot more sense and I'm sure it is a lot more effective.

That Jet's dust collection is pretty much the same as the Jet's closed stand model...

Thankyou John. I enjoy the challenge of working with sheet metal. If anyone is wondering what I used for a JET color match, it is Rust-oleum Painters Touch, 249860 semi-gloss Ivory Bisque.

It is fairly important to me also. I'm up here in North Dakota where it gets brutally cold. After a couple of winters working in a enclosed shop with no dust collection and or air filtration, thats when I said enough. Not only for health reasons, but safety reasons also. I have a forced air wood stove in the shop and the dust would get so thick in the air that I was very worried that I might blow the place up. The added bonuses are less time wearing a dust mask, and less time cleaning up at the end of the day, which is also important to me because the main shop is in the garage where we still park our vehicles at the end of the day. I also have a small projects shop in the basement where I need to keep the dust from circulating in our home.

My Delta has similar dust collection chute.  Has never been a problem.

Dan, what your Delta came with may work good enough for you, but if it is a JT360, the dust collection setup that it came with is not as efficient as it could be based on basic dust collection guidelines, which is no tight radius turns in airflow. It's easy to see that the stock setup in the models that described in my first post is much worse then a tight radius elbow. From the looks of it, someone at RIDGID knows the dust collection rules also.

I have operated my jointer with and without the dust collection port for many years.  It is adjusted to cut fine shavings from the wood creating very little dust.  When running a lot of wood through the machine the dust collector can fill up in no time.  I often opt to remove the port and let the shavings drop to the floor and manually sweep them up.  The shavings slide down the chute without backing up so any suction added to that process would be a benefit.   I set up the dust collector hose to act as an air cleaner sucking away the small amount of air born dust that comes off it.

( Dan writes : I often opt to remove the port and let the shavings drop to the floor and manually sweep them up. ) Why remove the port if it works so good ?  I noticed that it looks like you have some kind of hose adapter inside the dust port, as if your using a shop vac rather then a dust collector.

Your answer is the first part you decided to selectively remove from what you quoted from me.

The machine pictured is from the internet and not my actual machine but is the same model.

 

 

I'm sorry, but I just cannot do this anymore. I wish that I had never shared ANYTHING on this site. What a horrible waste of my time. Good luck, and good riddens.

I don't see any criticism here Charlie. Just one man telling how he handles dust collection, or not, in his shop.I think your input is appreciated here

That is right because everyone does it different . Does not mean anyone is wrong or that having a different method is criticism of another
