The use of CA glue in treating bridge cracks is for the money the most effective and thorough treatment. Especially when considering the age and value of the piano in question. Bridge cracks are elongated and continue, since bridges are laminates, sometimes to the very end. A partial dosage will fail. The beauty of CA glue is it's ability to find the end of a crack. When it's right you get the excess flowing back out. But because the cracks can't be seen, a situation can seem to be solved when it has only just begun. Epoxy, messy and sticky is incapable of completely filling the crack. Sonically, CA has more to offer. It forms a solid, complete transfer of energy. But if it is used inexpertly, it only causes a larger problem. Removal of CA treated pins might be a bad move, breaking the cap is the first such thought. I would lay the piano on it's back and complete the treatment. Save time & money. P Wethington RPT
