I think I ended up using new bolts to attach it to the DC housing, as I seem to remember the originals being too short using the 1/4" melamine. Just be sure not to use bolts that are too long, they won't hit the impeller, but would likely cause turbulence and impede material flow. A separator is also something you will want to think about. It will removed the chips and the majority of the dust before it gets to filter, there by keeping the filter clean and allowing maximum flow. Also, fine dust smaller than the micron rating of the filter that doesn't reach the filter won't get through it. I built a "top hat" design that sit atop a trash can, and dump it instead of the collection bag. My collection bag barely gets the slightest bit of dust in it.
As Alan stated the impeller is smaller than most, measuring 9.75", but the 12" impeller from a Rikon 60-200 DC is a perfect and easy direct fit replacement. It was $60 + shipping when I got mine.
