Stu:

Though not a list of others that have done what you suggest, here's an
example from my old workshop. It required a 55 gallon drum with
removable lid, some PVC pipe a few screws and nuts, and some caulking...

It took a short bit of time, but was pretty cheap, and after it was in
use, I found out I could remove the bag filter for all but the finest
sanding dust... Doing so provides a bit of extra suction for the
longest run in the shop.
