After I removed the electric motor and blower unit from the wet/dry vac, I contemplated how to attach the leaf blower in its place. I decided to just cut a disk of plywood that would fit over the top of the wet/dry vac's tank. I used a jig saw to cut it out of a piece of 3/4 inch plywood I just happened to have lying around. I put three screws in with their heads sticking up a little for the hold-down clips on the tank to get a grip on.

Then I cut holes in the disk to accommodate the leaf blower. I not only needed a hole for the leaf blower's air intake, but also holes for various protruding pieces that would otherwise be in the way and not allow the leaf blower to sit all the way down flat on the disk.

The third photo shows the leaf blower test fit on the top of the vac. It looks good, but there are a lot of air leaks that prevent the vacuum from developing good suction. I needed to add weather stripping.
