Getting the motor mounted will allow a lot to be learned about the necessary torque and speed for this project. In my experience, motors are notoriously difficult to mount. The approach to this motor was to select and appropriate bolt size for the holes in the cap and tap them.
Tapping was a delicate procedure since flakes of metal could get into the motor. It was kept upright during the whole procedure then a needle-nose pliers and a curved pick were used to clean off the internal magnets. Once the motor was clean, straight braces were attached with bolts and washers.
#10 (5mm) bolts were going to be used to elevate the motor and braces but only two were available which were long enough. Holes were marked and drilled into the board for one of the braces and the available bolts were enough to hold in place temporarily.
