I bought a yellow dust shoe for my XXL from eBay. It works ok but is 1.5" and my dc is 4 inch 1.5 hp Jet dc. The 1.5" is starving my cfm. The suckit seems a better option than router mounts dc but suckit is hopelessly behind on production.
What are you using for the dust shoe and what are you using for a dust collector.
FYI my Jet has a 30 gal trash can 4 inch cyclone can separater. I get very little dust in my dc bag if I keep the 30 gal can less than half full.
