I have been using my Makita ratcheting driver for the corner jacks. I forgot about the actual brother Makita 'two speed drill' I have, I guess it may have more torque. With the ratcheting driver, obviously I've had not 'wrist twisting', but thanks for the reminder when I now will try the drill. Unfortunately, my Makita LXFD01 18V drill has no room at the nose to mount a 'T' handle. / I wonder if holding the base with the other hand would help?
