I recently had an experience in which I glued a broken key button with CA. I clamped it and left it for 30 minutes while I did other repairs. The glue joint failed immediately. I started again with Titebond. The joint held after I had finished my other work. I attributed the CA failure to the fact that I had run out of accelerator. I seem to have observed CA failure without accelerator on a variety of occasions. I haven't noticed enough about the particular conditions to explain the difference. Bob Anderson
