Huh, interesting spam approach.
I've removed the text, have no way of restoring what was originally here.

It sounds like you are wanting to attach a separator to some sort of shop vac. There have been a number of threads, some with photos, describing various ways of doing that. Some are built right into a modification of the vac, and some sit adjacent to the vac on a cart built to accomodate both. To the best of my recollection, most of these builds have worked satisfactorily.
Unfortunately, I can't quickly find any links to these threads. You might want to do a search on shop vac or shop vac separator. That might lead you to some useful information.

It works very well. I have now installed a Cleanstream HEPA Filter and the improvement is quite noticeable. As a side bonus noise has gone down a lot. These filters are washable and I don't need to use that extra cover anymore.
The diameter of a 5 gallon bucket isn't much more than 10 inches (The OD is around 11.8 so subtract 2x the width of the lip at the top) so I would say that it has likely been done quite a bit. Do a search on the forum for "bucket" and you will find quite a few threads about them.
