repair clock

normally when i take the screw driver, it was been instruct by people - my 3th uncle.
after he stay with us, our broken thing also is repair by uncle.
but this time, i repair my birthday clock by myself n also is the first time...need thanks to my sis job - make the clock's leg out =="
but it is just a normal job, take out the screw and turn in back the leg, but it is take around 20 min...=="
easy to screw in but hard to take out.
