Two questions for the woodworkers who are also chemists:
I have some thick CA glue, so thick that I can no longer use it. Now I know that I can add acetone as a thinner to normal thick CA glue to make thin/thinner CA glue, but can I also add acetone to the thickened thick CA glue to reconstitute it? I have already tried this and have used the results on some jigs, but my concern is more whether this reconstituted CA glue will have its full strength, such that is is suitable for real projects.
In other words, can CA glue be reconstituted the way traditional nitrocellulose lacquer can be redissolved? or is it like varnish, which, once it starts to cure, will never be the same.
My second question regards gluing over Boiled Linseed Oil. I often wet-sand my turnings with boiled linseed oil, but lately I have been making composite turnings by gluing more than one turned part together. In some cases, I can glue the parts together first, and then wet sand, but often it is easier to wet sand with the boiled linseed oil before assembly. No matter how careful I am to avoid getting boiled linseed oil on the surfaces to be glued, it is unavoidable. It would be ideal if I simply did not have to worry about this and was able to glue the surfaces finished with the boiled linseed oil. Is this possible? with either CA glue or epoxy?
