Put a nut on first before cutting. this particular application is very tolerant of spacing, but try to make the center hole an accurate size for the motor centering boss. If I remember correctly, It was a D drill, with minor deburring. test in some scrap first.
Sorry if I misled anyone on the drill size to center the Tetrix motor. Sanddrag is correct - 25/64" is the closest size. Must have had a Senior Moment! We made spacer bushings to go around the boss, so we could drill out the hole large enough to pull the motor/ driveshaft assembly out quickly just in case a motor failed on us. This info might be especially useful to those that pressed a driveshaft over the pinion gear. Not neccessary if your driveshaft diameter is less than .3906 in.
