1: put a belt or something similar around the ratchet to avoid gouges in the chrome
2: put the ratchet in a vise
3: if you want to save the handle use something to protect the handle from gouging(open ended wrench, washer, etc.) then take a couple of prybars and remove the handle that way
4: align the handle the way you want and put it on with a deadblow
For soft handles:
1: boil some water
2: put the handle of the ratchet in the water for about 3 minutes
3: using hot pads(the handle WILL be hot) hold the head of the ratchet in one hand and pull with the other hand on the handle
4: align handle and drive on with a deadblow
