CA glue expands the wood fibers, and then promptly solidifies in that configuration. I've had great success with it, and it's an easy process to explain to customers. I have no experience with other methods, so I simply have to trust the wisdom of those who have used both and typically claim the CA provides better, and longer-lasting results. The obvious cons to CA are the fumes, and the concern that a re-application (if ever needed) may have little effect, since the wood fibers have already absorbed what they are going to absorb. And one final warning about CA that you don't hear too often: Don't use cotton rags with CA glue, because you could have a fire on your hands. I once had a cotton rag get very hot in my hand and start smoldering because some CA got on it. Here is a video of a cotton ball catching on fire just by applying CA: http://www.metacafe.com/watch/613004/spontaneous_combustion_how_to/ ben at benspianotuning.com wrote: > Hello all, > > I don't want to drive the subject into the ground, but I have a few questions that haven't been able to find answers for in the archives or from fellow technicians: In regard to pinblock tighteners, are there advantages to using one product over another?
