Thanks again Charles. The 2 1/4" exhaust port for the Jessem table/fence is in the fence above the table. Because of the 3 1/2" diameter of the roundover bit being used, I am not using a tab lock ring in the Woodpecker lift plate, and for safety with this large diameter bit, the PC7518 is being run at its lowest speed, 10,000 RPM. Thus the PC7518 motor shaft end has maximum exposure to shavings and minimum air flow to keep them out of the motor. I have not observed any shaving accumulation on top of the PC7518 shaft end after running a 4' long, 2" thick mahogany test piece so it appears the PC7518 exhaust is designed to handle this max exposure, min air flow situation. The ShopVac is sucking a percentage of the shavings but not all, there is a fair amount of shavings that accumulate on the floor. The 2 1/4" dia, 12' long, exhaust hose is routed downward after exiting the Jessem fence exhaust port enroute to the ShopVac to help the ShopVac keep up with the shavings but perhaps the 12' hose length may be excessive. However, I'm reluctant to cut the hose shorter unless there's a definite need. I don't mind the shavings on the floor, I just don't want them getting into the motor case.
