@furboo

My Unisaw has a 6" sheet metal outlet and I used this to go down to 4" for my DC 6 in. to 4 in. Round Reducer or Increaser-R6X4 - The Home Depot

Because I move the hose between machines, I have the Rockler adapter Dust RightŪ 4" Tool Port with Clamps, 2 per Pack | Rockler Woodworking and Hardware attached to the reducer, with the quick disconnect mounted on the hose. I have the 90° adapters mounted on my router table and miter saw so it's a matter of seconds to move the hose from one machine to the other.

Rob I lust recently got the Super Dust Depot and ordered the 6x4 reducer and the 5 x 4 reducer from Rockler (they sell the Super Dust Depot) and the reducers did not fit so I sent them back. I than called Woodcraft they also sell the Super Dust Depot and both reducers I asked then to see if they fit the S D D and they could not get them to fit. I asked why do you sell the reducers that don't fit the SDD. They didn't have an answer. I ended getting fittings at the local Ace Hardware.

I may give this a try.
Rob......I had forgotten about this, too. I'm setting up my system, and have been having fits trying to get adapters to fit. Apparently 4 is a variable number. It will take a bit of work to make the forms, but I think worth a try. At this point, I'm not as worried about cost differential as I am about getting stuff to fit! Thanks for the reminder.

Yeah, searching around on acceptable diffuser angles, it looks like a about a 7 degree expansion (from the centerline to each side) should work ok. For a 2" change in diameter, I get about 8-1/4" long (minimum) for the transition. The longer the better. Herb's idea of riveting up a bigger stove pipe sounds good.

Herb, I see smaller reducers on their website, but not this big (6" x 4"). My closest Lowes is a 40 mile drive, and I like to ensure something is in stock before making the trip. Fortunately, their site is pretty good at what's in stock.

The closest Lowes that stocks 6" PVC is about 100 miles away (Albuquerque), and I finally got by there yesterday. Of course, now I'm learning I probably need more

The fittings Ray made are one thing, but thinking about this more, I don't know if I'll be able to squeeze down a 6" to 4" by heating it up. That's a pretty big change. I'm going to play around with some smaller (cheaper) PVC first.

Default Can of worms

The world of PVC plumbing pipe, dust collector pipe, HVAC pipe, and dust collector hose is a real can of worms. Between incompatible ID and OD it seems like I am forever looking for the elusive silver bullet adapter! I have had good luck with what the plumbing world calls hubless connectors. These are basically a rubber hose with a stainless steel hose clamp on both ends. There is a shielded type that also has a stainless steel cover but that limits the stretch and is to be avoided. These come in all sorts of transition sizes and shapes, including some angles, and are very stretchy for either going over large pipes or will squeeze down for smaller pipes.
Good luck, I feel your pain.

Rob what did you end up using for your 6 to 4 inch reducer?

I am using my reducer at the end of my 6 inch trunk line where it ends on the machine side away from the SDD. I have all my tools setup with quick disconnects with my 4 inch hose. I sold my old DC but kept my hose and quick disconnects as they were already setup. I needed something on the back end of the hose which would fit so I could continue using my quick disconnects.

Woodcraft sells the quick disconnects which I bought using my old DC.

I did find a 5 to 6 inch reducer which would fit the SDD at Woodcraft. I am running 6 inch pipe to the machines. I know it is not great but I could not find 5 inch pipe. I think I need a little resistance going into the SDD since is meant for 5 inch pipe and I am using 6 inch.

@coxhaus I haven't come up with a 6x4 reducer, yet.

I'm still debating whether I want to go the SDD route. The SDD XL comes with a 6" hookup, so at least with that you avoid the 6x5 reducer. See

https://www.oneida-air.com/inventory...-E5F28583241B}

My problem with the SDD is cost and the increase in height of the overall DC, which I'd like to avoid.

Thanks Tom! I may use that until I can come up with something more elegant. My local store actually has those in stock.
