Thanks, I'll try that tip the next time I run into problems!
I'm planning to use thickened fiberglass resin on the inside seams & fiberglass mat/resin where the handles are attached.

The wood ring used to connect the hose to the lid will also be sealed with fiberglass.
The inside of the lid will have a foam-rubber weather strip along the inside edge, The inside wood ring I sealed with some left over OSI Quad caulk.

Does it collapse any if there's a blockage, or if the inlet was closed with a blast gate?
I'm thinking of reinforcing the inside of my metal can with several metal rings?
