A friend has one of those 'antique' piano stools that he uses daily for dressing and other weight intensive purposes. It had been disassembled four times for regluing but the joints broke apart within a year at most. I used cinch straps to tighten it up then dribbled thin CA into one joint at a time until a stable meniscus appeared upon which I used accelerator to set the glue. Six years later it is as tight as the day I glued it up; and this after daily use. CA wicks into every crook an nanny, fills every void, then set HARD and unyielding. I have used thick CA to fill cracked and chipped plastic keytops. I quickly learned that the glop has to be carved within minutes otherwise it sets harder than the plastic and is difficult to work. Files and sands nicely then buffs up well. The repair is visible but not feelable. Great for older practice room pianos. CA cures in four hours with accelerator, can take a day or more without. It is great for securing loose bridge pins IF the hole is filled entirely, bottom to top, until a stable meniscus appears, then the corner of a tissue wicks up the excess. Allow a day or so to cure. Good stuff if used intelligently. Newton
