Cyclone bucket lid reinforcement

The cyclone works so well I had some trouble keeping my bucket and lid from collapsing.

To keep the lid from bowing I made a quick "washer" to cover more of the lid. Then I laser cut two of these rings and used them to sandwich the bucket lid. Works great.

To keep the bucket from collapsing, I'd heard that simply putting the dust collection bucket in another empty bucket would fix the problem. I was a little skeptical, but sure enough it works!
