UPDATE:

Well, the dust topper bit the dust (pun intended) already. All of the sudden my shop vac wasn't giving nearly as much suction and I found that the 5 gallon bucket had imploded. Yes, it was a "homer" bucket as specified by dust topper.

At this time, I'm still using the shop vac setup, but have simply equipped it with a fine filtering bag. I think the dust topper is going into the garbage unless I can find a way for it to be useful.
