A while back I tried my hand at making a strum stick for my son and was added to the Stewmac email spam list.
I am not a luthier, but every once in a while I find an interesting product that I can make good use of in my woodworking.

This morning I received an add for tinted super glue. Hmm that’s interesting I thought. But digging deeper I found this “trade secret” on which super glue to use that I thought was worth sharing. Very informative for me, hope it helps someone else as well.

I use CA a lot in my other hobby, fencing armory. There are, of course, wide variation between vendors in viscosity, but you can usually find thin, medium and thick versions of most quality vendor’s products. I’m partial to Zap, but Bob Smith Industries is also very good. Pretty much as the linked article says, you use thin when you want wicking, and thick when you want it to stay where you put it. The thinner viscosity holds faster, so if you need fast hold, go thin, and of course accelerators make any viscosity hold quick. You can’t expect a thick CA to hold instantly with accelerator. Thin will. I prefer to use the accelerator on one side and the glue on the other side, press together and you get an immediate hold, but I only use accelerator when I need it. It still takes 24 hours to go to the maximum bond strength, but you get a really tenacious hold after 15 minutes without accelerator and a few seconds with accelerator. When in a pinch, water is an effective accelerator, although it will cloud the otherwise clear glue color.

CA has a shelf life. If you don’t use it a lot, buy the small bottles. You can clear the nozzle of the thin CA with a pin or needle. That’s less successful with the thicker viscosity only because the nozzle is bigger and there is more hardened glue to dislodge. I try to cap quickly when I’m using CA and I make sure the nozzle is clear before I put the cap on. Better glues have both an inner seal and an outer protective cap.

Keep debonder around for when you glue your finger to something :(
