To replace a hammer handle, identify the shape of the handle, place the old hammer in a vise to remove the handle, measure its length, and find a ready-made handle for replacement. Tools required for this task include a vise, a drill and a spokeshave.
Some handles have a round shape, while others are octagon in shape, so identify the right shape for the handle before purchasing or making one. Grip the hammer head in the vise, and remove the old handle using the drill. You can choose to retain the original length or choose one that is the best fit when looking for a replacement handle. Grip the handle in the vise, and insert the head. Use the spokeshave to trip the end to allow the head to fit correctly. Complete the task by driving wedges into the head for a firm fit.
