So when I originally setup a 6”-ducted dust collection system, I built an MDF box that attaches to the back of the stock Grizzly fence housing. The 6” duct that entered the top of the hood split into a fence opening (~5” duct equivalent) and a 4” PVC line that was pointed at the spindle. When I went to oil the machine recently, I noticed that that the under-table collection was under-performing. I like the design of the silicone Keen accessory for router table collection, so I decided to scale it up for a shaper with lots of spindle travel.

First I heated up a piece of 4” PVC pipe to form a smoother transition from the 6” inlet to the 4” outlet. Next, the spindle “boot” was made from a sheet of rubber. The surface was temporarily masking taped for easier layout-lines. Vent slits allow sufficient airflow and make the boot easily collapsible for spindle travel. After lots of tedious seaming, it was ready to install. For installation, a custom steel washer bolts the boot to the spindle housing. Finally, three tabs keep the boot’s upper pinched under the table’s steel insert.

Now if I can just come up with a similar solution for the cabinet saw…

Very nicely done. Thanks for posting! I have the same shaper. Will be looking into this idea.
