− | This is a 2.5" duct, 'cause I originally planned to use the shop vac. The hole can just be enlarged to 3" w/o other changes. For 4" or 6" gates, the plates should be enlarged, and linkages will probably need lengthening. I made a lot of paper models to get the geometry right. Someone with experience modelling moving parts with CAD could probably do the scaling more quickly. | + | This is a 2.5" duct, 'cause I originally planned to use the shop vac.
