I have had an avid interest in adhesives since I did a term paper on them in advanced chemistry bach in 1962. Jeez that was a long time ago. My wife calls my passion the "adhesive of the month club". I have a few favorites. West System just came out with a very strong yet flexible epoxy that their techs could not even believe. It is G-Flex. It is a bit slow setting but great for things like rib repairs to soundboard or moving wooden parts under high stress. Usually strong adhesives that set slow and are strong are also brittle. Not this one. It has good penetration too. As stated before about the green piano bridge, I like JB Weld and Marine Tex black for high compression resistance, machinability and heat resistance up to 240degrees F. It can be used to repair an autoclave door flange. Very little creep but it is a bit thick and won't penetrate too well unless warmed up. I use Weldbond for all kinds of things. I carry a small bottle of it in my tuning kit. It looks and handles like Elmers white glue but is much, much better. It was designed to glue tiles on the space shuttle. It is great for wood. You can even glue wood to metal, glass, concrete, and plaster with it- or any of them to each other. It dries clear. An elastomeric that will stick to nearly everything including those molded high density polyethylene kids toys that resist any other glue including epoxy. It is the Welder. It works like a contact adhesive (rubber cement or Goop) but is stronger and will not yellow or become brittle like Goop. Great for gluing felt and leather. Fix your shoes with it too. Another that is a bit hard to find is a CA glue called PascoFix glue. It is anaerobic ultra pure medical grade CA glue. It can be used in dentistry. Anaerobic means that it sets quickly even without oxygen present, like tight fits, under water, inside the body, etc. It can glue where some CA glues fail miserably. It can even be used to glue rubber patches on tires. There is an accessory Pasco filling powder that can be piled up on a part to fill in a missing portion like a broken plastic part and then be polymerized with a drop of the PascoFix. This polymerized powder (now a very hard solid) is very strong, can then be machined back to any shape and be as strong or stronger than the original part. I think the powder is acrylic powder. This stuff is amazing. It has saved me a few times by reproducing a plastic part with missing portions that was otherwise unavailable. Happy gluing.
