Spindle Mount 500watt Motor CNC

This Spindle Mount bolts to my 2080 or 2040 eight wheel carriages, all M4 hardware is used, recommend allan head bolts so they can fit down in the cap. The spindle motor that fits this mount is 400-500 watt 52mm diameter Chinese cnc router spindle motor, the one I have is brushless but I do believe the brushed ones are the same dimensions (52mm diameter) and should work.
