These Seiko motors will operate a second hand, but second hands are considered optional. See the bottom of the motor page for the link to our selection of second hands. Seiko motors require a .034 - .035 diameter second hand bushing as shown below. This hole size is too large for many other motors..All models have a 5/16" shaft diameter so a 3/8" mounting hole is the correct size to drill in your case.
