Folks have asked about my custom rodded Delta 50-760 DC. My camera batteries died tonight so I'll have to get some updated pictures to show a couple of finishing touches to the DC, but here is a description of the individual parts:
Starting from the Oneida Super Dust Deputy and moving over to the Delta, the parts are: Nordfab 6" machine connector. Nordfab 6" clamp. Two 90 degree Nordfab elbows with clamps. Nordfab 6"/5" reducer with Nordfab 5" machine connector and clamps. Penn State 5" "inside/inside" (don't know what else to call it) connector that happens to slide inside the Nordfab 5" machine connector. Penn State 5" spiral pipe (I have a 5' pipe from which I cut this short, seven inch piece) into which the "inside/inside" fits. And the spiral pipe fits over the 5" intake of the Delta.
To be honest I'm not certain of how I cobbled together the intake of the Oneida. I've had this connected to my Delta for several years; it was cemented to a Jet separator lid (which I had opened to 5") sitting on a trash can. I think he 5"/5"/5" wye is from Penn State. Somehow I got that to fit with two 5" blast gates that look to be Nordfab. Again, I constructed the 5/5/5 set up years ago.
To assemble this hot rodded DC I used parts I had in my basement. If I was to do it from scratch, now, I'd use all Nordfab.
The whole thing sits on the plywood (from the crate in which my Powermatic 2700 came) which I have now bolted (I'll take a few new pictures to show the finished product) to the Delta's base. Rockler locking casters now adorn the plywood (Rockler's casters are taller than Delta's casters, but in this application they are perfect given the height of the plywood).
Finally, this evening I fashioned a brace to wedge under the 5/5/5 wye to keep the whole apparatus, with attached hoses (and another wye), from pulling down on the Oneida's intake.
Amazingly, I had ALL the stuff in my house. It took pretty much a full day to figure out and assemble this with what I had on hand.
I can tell you that the CFM I'm getting now is FAR BETTER than it was with the Delta bag filter. I attribute this to the Wynn filter, the smooth surfaces of the steel duct, and the relatively large radius of the curves in the elbows. Keeping flex hose out of the equation is key.
All of this fell together when I happened on the idea of inverting the Delta.
