Dust Collection Fitting For a Delta 31-710 Belt Disk Sander

[Roger Davis]

I have a Delta 31-710 6 x 48 inch belt 12 inch disk sander. The dust collection outlet port on the belt sander measures 3-1/4 inch outside diameter. I have searched various woodworking sites for fittings and hoses that would fit this size dust port to no avail. Has any creeker solved this on a like machine? Thanks, Roger

I had a similar situation with another machine. I used foam weather stripping to close up the gap with sheet metal screws to hold it in place. Another possibility would be to cut out a disc of rigid foam or plywood to fill the gap.
