I recently received my Hammer K3 and am trying to figure out the best approach for connecting a 2.5 inch dust hose to the 50mm blade guard port. I contacted Hammer/Felder support and they said they don't make any couplings that convert metric to inches. On the main dust port I found a rubber coupling at home depot, but haven't been as lucky with the blade guard. I've surprisingly had a hard time finding a 50mm to 2.5 inch reducer in any of my searches online as well. Does anyone have a link to one they know fits? I know it's out there and probably easy to find, but for whatever reason I'm not searching right.
