Vacuum hose adapter

[art_d]

I have a new table saw with a 4" O.D. hose connection. I want to connect my Sears shopvac with 2.5" O.D. hose connector. What do I need?

A bigger dust collector.

They put that 4" hole there for a reason.

I agree that the larger diameter hole is a far better idea, but until you can afford a bigger dust collector, this might work:
