Oneida Air Systems Dust Deputy 2.5 D.I.Y. Manual page 12

Additional D.I.Y. Ideas
You are only limited by your imagination. The lid must be sealed
airtight and the container must stand up to your vacuum's suction
pressure without collapsing.

Deputy 2.5.
Examples of DIY setups
[FIG. 7] is an example of a plywood top that had a groove routed out
of it to fit the bucket rim and accommodate the gasket. For mobility
and additional stability, you can make a plywood platform to fasten
your bucket to. We recommend 5 casters for the best stability.
