How do you do tapping on a mill or lathe without encountering clearance problems?
Here are a few ideas I have found:

This is a standard 0-3/8" drill chuck with a 3/8" x 24 threaded mount. A short length of 3/8" dia steel rod for a shaft. Old long shank drill bit for a handle. The shaft rides in a standard 3/8" ID, 1/2" OD oilite bearing. Just chuck this thing into the mill, drill press or lathe tailstock. This size does 1/4 x 20 into steel. 3/8 x 40 into cast iron.
