The manual says you can use a Jointer on the Power Station but as JPG said slow speed, slow feed. You cannot use the Mark Mount Planer on the Power Station since it mounts differently than other SPT's. The speed range for the Power Station is 850 to 3850 RPM. I have two of them and I keep my Scroll Saw on one.
Mark V 520 S/N 09-11-01 completely upgraded to Mark 7, with all SPT's & more.

Model 10E S/N 1077 oldest one I have restored. On bench w/ Shopsmith metal ends & retractable casters.
