Leather Key Bushings

<< My understanding from another local technician (who has used them) is that

they are not as adjustable as felt so they are harder to fit.>>

Greetings,
    I don't use leather, because it's service life is short.  It lasts a long 
time, but gets noisy quicker than felt. 
However, it is easy to size.  Get the leather a slight bit thicker than you 
need, and then put a sanding drum in the drill press.  By placing a block of 
wood the correct distance from the drum, you can sand down the felt strips to 
whatever thickness you need by pulling it between the drum and the block.  Watch 
your fingers!
