Rather than removing the caul, I use a rotary razor blade (available in fabric stores & Pianotek) with the caul in place immediately upon insertion of the felt and caul. Works like a charm. If you soak the bushings well, you shouldn't remove any wood. I use a 50/50 mix of alcohol and water and put little felt squares in the mortise between the bushings to hold the moisture in there. Let the water to the work for you - several hours - if the bushings are not falling out, they are not ready yet! And then use Spurlock's mortise sizing cauls and let dry overnight, etc. Terry Farrell ----- Original Message ----- > Looks original to me.
