Tom -- Thanks for the corroboration. I've never heard of anyone except me using CA this way, though it can come in very handy at times. I've done it for about 5 years. While I mainly use CA and white glue with cloth or felt, it works with leather too, and sometimes I glue wooden parts together the same way, holding them together with my hands till the CA sets. I haven't heard of the joints failing so far. I try not to stress them overly till the white glue would have set up anyway. Wooden parts that fit together very well could be glued with CA alone, of course, but I use the combination when they aren't quite such a close fit, but the contact isn't poor enough to demand a gap-filler like epoxy. I think you're right about which glue is doing what, and I hadn't heard about the pH data, but it may account for the results. I always thought that the white glue makes the real glue joint, while the CA just holds it closed long enough for the white glue to set up. It takes a surprisingly small amount of CA to work. I'm glad you tried it out. No substitute for actual experience. Anyone else?
