So, you love the convenience of the INCRA Mast-R-Lift by JessEm, but you don't own a Porter-Cable 7518? You may not need to save up for a new router.
These heavy, solid-aluminum reducing collars can adapt several popular mid-size router motors to the Mast-R-Lift's carriage. The motor is removed from the router's base, the adaptor collar slips snugly over the motor, and then the motor/collar assembly is secured in the lift in the normal fashion. The benefits of precise height adjustment and above-the-table bit changes are retained when using an adaptor collar.
