https://www.exoticblanks.com/E-Z-Bond-Thin-CA-5-CPS-Choose-a-size.html I used a lot of CA glues when I was making pens on a lathe. You could reinforce woods which were so rotten that your fingernail could cut right through them. Soak the soft areas with a little CA and let it set for a minute. It gets hard as a rock then and you can cut it with sharp tools. CA comes in different thickness with CPS numbers to tell you the general thickness of the liquid. Thick ones penetrate poorly but fill larger gaps and are generally stronger but much slower to cure. The thinnest stuff I could find was this one above. CPS5 is much thinner than water and penetrates wood very well. Once it sets up it is very stable.
Beware it sets up quickly and is exothermic. Gets hot as it sets up to those with liberal arts degrees. If you squirt it on paper towels and throw them in a pile they can get so hot to become a fire hazard. Use in well ventilated areas and have safety glasses and latex or latex free gloves on your hands. If you get the CPS5 on your fingers you will instantly glue them together and give yourself a decent second degree or worse burn, if you get too much of it on them. This is so thin that it tends to splash droplets easily and just one drop near your eye will ruin your month. Also CA glue is a Cyanoacrylate compound and we know is not good for your health, so use in well ventilated areas. People do become very sensitive to using it and some become very ill if used poorly.
