I remember making glue with different solvents and ping pong balls. The two (1 1/2?) solvents I remember were acetone and methyl ethyl ketone (?). The problem with the acetone was that the glue was very brittle, "crisp" and joints didn't hold up well, often warping a tiny joint as it dried. The glue set up in the syringe too quickly as well. There's another solvent used in lacquer and glue that I can't remember at the moment but I do remember discounting acetone as a viable solvent very quickly. Ultimately it was Ambroid that won out, sometimes thinned with MEK or another solvent.

What's the matter with the new Ambroid?



Other than the mustard smell (which is a total bummer), it seems to work well for me.

The result is a decent glue, possibly suitable for indoor, or at least I will be doing more careful weight/strength tests on both these after I run out of my 8 tubes of Ambroid. One downside--many celluloid guitar picks are brown, so that's unsightly, if not a source of extra weight. The ping pong ball glue color blends well enough on balsa. Years ago I remember plain amber translucent celluloid guitar picks somewhere, and possibly clear ping ping balls somewhere.
