This or a similar method is by far the quickest, least damaging and least tiring way to remove hammer-heads. The German tool sold by Jurgen is certainly a fine tool if you need to save the heads, for example if they have been glued on incorrectly or wrongly bored and need to be adjusted, but for a new hammer-head job it is not necessary. I use a pair of 6" end nippers, the same as I use for centring. I fitted new hammers to a Steinway this week and removed the old heads this way. It is important not to split the hammer tail in the centre to start with, since that way you can split the shank. Instead split the tail longitudinally at a tangent to the shank. I then usually crush the moulding across the grain using the nippers just above the shank and then the shank can be twisted out with no effort. Very little glue or moulding wood is left on the shank and this can usually be quickly scraped off with a knife. Besides, the end of the shank is not crushed, as it is with the press tool, especially if the hammers are tightly glued on.
