My bandsaw has a 4" port on the bottom of the right hand side therefore no dust extraction at the table.
I adapted Rob Cosman's idea, using domestic waste pipe & my shop vac, so that extraction takes place immediately underneath the table as well as the bottom. Seems to work fairly well. Certainly a lot less loose sawdust than there used to be.
Sorry no photo. Will try a take one tomorrow, if anyone is interested.
