The way I do it involves a drill press, I find a faster with the same threads as the screw, cut the head of it off, thread the fabricated screw into the insert, put the guitar on the drill press table, chuck the screw into the drill press (leave yourself some slack to pull up on the handle), Clamp the guitar to the table, and pull up on the handle. Its much easier than it sounds! The reason I do it this, this way is to make sure the bushing comes out cleanly and perfectly staright! Reduces and possibly damage to the wood or finish on the guitar.
