Tightening key bushings

[Michael Gamble]

Hello List and RicB
I've often come across keys which have been "knifed" open along side the
bushings and the new slot thus made shimmed.... Also there is a special tool
extant with a sort of inverted "W" on one side of the metal block. On the
other side it is flat. The object is to place the key, ivory down, on a
solid bench, insert the middle of this "W" in the bushed slot and then bash
the other side of the block. Sounds a bit crude - don't even know whether it
works or not - but it's available........
