Hi Don, In our neck of the woods we see a lot of pedal and lyre problems. At one time I use to knock them apart make a new maple shim and reglue, and it took several hrs, time I was through. Now I just hammer the joint back together, tape the crack with PVC electrical tape and fill all the voids with medium viscosity CA glue. I also treat the end grain of the dowel with low viscosity CA glue. This type of repair has stood up well on university pianos that recieve a lot of heavy usage. For the last two years we have been treating the end grain of the dowels with low viscosity CA glue on all new pianos. Our field failure rate has dropped to zero, where as before failures were a common occurance. In low humidity conditions it stops the shrinkage and hence the joint failure. Note the PVC tape, the glue will not stick to it, or wick into it. Masking tape absorbs the glue and you will find that you will have lots of clean up.
