Rogerio & Warren,

What Rogerio probably means, is that the groove where the center pin fits in
is too large to hold the pin properly. One way I had to go with before
replacing the butt is to file the flat part of the butt below and above the
groove so that the groove gets smaller. So you have to remove the plate,
file away some of the wood and then just reinsert the plate and the flange.
It has worked for me.
