Play matchmaker with dust-collection hoses
One of the most frustrating parts of setting up good dust collection is the lack of standard fitting sizes. Often, I resorted to duct tape to join a hose and tool port. Then I came up with these simple adaptors. Simply trace the diameters of the port and hose on scrapwood blanks, cut or rout the holes to size, and sand the inside profile until you get a snug friction fit over the hose and port. Glue the two pieces together face-to-face, and you've got a cheap, effective adaptor.
