In a message dated 98-03-17 11:45:34 EST, you write: << Dear Glen, list -- I've heard the same thing about CA glue. I've never noticed any joints coming apart, but when one is gluing (for instance) action parts together, which hopefully will be in use for decades, this problem is certainly something to consider. >> I did a pinblock repair on an upright using CA glue. The problem is that the separation was very deep. I did not have a large enough bottle of the thick CA glue needed and even after drilling though the pin block from the back of the piano, installing stove bolts and nuts then cinching them down, I heard the glue starting to separatate. I now have an Eilers upright in my shop that I am rebuilding and found a pinblock separation. The original scews that held the plate was only about 3" but the separation was at 4". With 20 pounds of tension, is it surprising to find the separation? For this repair I used the West Epoxy system because I have a lot of it (we have a dealer in our area) and it cures very solid. I drilled through, installed a washers, stove bolts and nuts at the plate area, then an acorn nuts on top for decoration. This looked especially good after I sprayed the plate. Since it is in my shop, I can monitor the repair and keep filling the crack until the exoxy is flush with the top of the pinblock. Food for thought. Dave Peake, RPT Portland, OR
