If you have the SDD, why would you want the wok upgrade? Both are designed to improve separation of chips and sawdust before the filter. If the SDD is doing such a great job, it seems like the salad bowl probably cuts down suction more than it's helping.

I would consider hard duct between the SDD and the DC. I'm betting you lose a lot of suction through that hose you have now. It's hard to get 5" PVC, but you don't need much. Maybe a 45 out of the DC, an angled pipe up to the top and a 45 down, with a short piece of flex so you can remove the bucket easier.

 

Good question.

I added the salad bowl as some of the Jet's and Powermatics have them. I am certain you are right that it might cut down on the air flow, but I guess i thought it might help keep as much of the fine dust from hitting the filter.

Thanks for the suggestion on the straight pipe. I will look into it. I could somehow attach it to the support beams and then use only the flex to attach to the top of the cyclone.

My original plan was to build a stand to hold the dust deputy and then have the dust collector mounted directly to the top of the cyclone. Then I was only going to use ~ 1 foot of the 5" hose to go straight down to a drum. When I started laying it out, it was going to get to big for my space and I ended up using the 5" hose as I have it in the picture. I think you are right on the pipe. I will look into replacing the hose with straight pipe.
