Both woodworking and metalworking machines share my shop space and are only separated by a short space. A shop vac and dust separator are used at my metal lathe and mill to vacuum up chips. It would be real convenient if my primary dust collection system could be extended and used on the metalworking side. I suppose it's possible to use an outlet of the system to support the dust separator in place of the shop vac but some metal filings could get by. Is there a metal separator that is used on dust collection systems? I don't want to get metal pieces mixed in with the sawdust because it is given to one of my neighbors for animal bedding.
