how to use it ????
thats a good ???... the feet don't look like there is mounting holes to keep it on the bench.. if u have a vise at home and of a good size u can use that just as well. small socket at one end to push through and larger socket on the other to allow the other bearing to fall into it... if u have a garage to work on the car and don't have a nice sized vise u need to get one then u'll always have other uses for it...
