I'll cite myself from yahoo IBX group:
As I was forced to replace several pushbuttons and both encoders on my
first-generation IB, I couldn't find a distributor that sells PIHER
encoders ( The original one is that make ) But I ran across el cheapo
Alps EC11E15244BY, a drop-in replacement with exception of the shaft (
as usual ). I overcame this by sinking the knob's bore to a total of 11mm
(3/8"), using a 6mm milling bit. The knobs slide on perfectly with a
slight press-fit and hold up well enough even when turning them
rapidly. For the more demanding, a concave piece of leaf-spring steel,
roughly 4mmx8mm, can be put into the hole and slid on the recessed
shaft together with the knob. That's it.
