Just bought a Delta 8" bench grinder and of course the dust ports are a different size than everything else I own. Anyone know where I can get 1 3/4" ID hose and a reducer or tee that goes from 1 3/4" ID to 2 1/2" so I can connect it to my shop vac? There are 2 ports (1 for each wheel) and I'd like to connect them with a tee and then to the shop vac.
