I've had a fair amount of experience with both epoxy and CA, and I disagree with this big time. The CA won't do anything useful except soak in, and it will prevent the epoxy from doing any good as a result, by leaving it nothing to stick to. Epoxy by itself will penetrate to the bottom of the crack, and into the surrounding wood plenty good enough to make a first rate bond if the wood isn't already contaminated with CA. Ron N
