I just bought a Super Dust Deputy. Its 5" inlet and 6" outlet are causing me big probs.

I have 6" hoses off my machines so I bought an HVAC 6" to 5" reducer (uncrimped at both ends).

The SDD's inlet is 5" (actually it's 5 1/8). And the SDD's outlet is 6" (really it's 6 1/8"). My hose won't fit over it either.

What is your advice to modify SOMETHING/ANYTHING to get these things to fit efficiently.

And - what are your thoughts re any advice so I can get this going fast -
- how much extra room do I acquire if I buy crimped reducers and "un-crimp" some of the crimps
- does it make sense to drill out the reducer's rivets, move the collar a little and use a #4 screw to hold it in the new position
- where to buy rubber-type plumbing 6" to 5" reducer fitting
Advice needed -- problem -- Super Dust Deputy - inlet and outlet sizing

Thanks.
