Terry, I just used to big screwdrivers and pryed the encoders off the
shaftby pressing under the aluminum boss and used the screw heads for the

Now that I am trying to do some other work, am building a small press out
of some flat stock and some screws so I won't have to worry about the
screwdrivers slipping (and that has happened)
