Eons ago I asked this question, and received several replies, but this time I'm going ahead with the project.
It has to do with glue holding an item in shear. Pretty sure that is correct term. If you're at all familiar with the Charles Eames molded plywood and leather lounge chair and ottoman, it would be helpful. There are four 4.5"x1.75" hard rubber with a metal base blocks, two of which support the back of the chair and two for the armrests. The metal is glued to the plywood, meaning when you lean back in the chair all that is holding it is the glue for the two blocks. Two broke off eons ago but fortunately a fellow has made new blocks which I have. He includes PC*7 a 2-part epoxy paste as part of the repair kit. I'm hesitant to use it it since it is now at least three years old - but could buy new if someone is familiar with it and agrees it would make a terrific bond for metal to wood. I'm currently filling some divots with JBWeld where some of the veneer broke off on one of the glue areas. I've considered using it, but not sure how it would work in shear. For the other, a large chunk of the veneer came off with the the block, which I've managed to glue the veneer back (much easier to write than do) using Loctite 2-part (extra time) epoxy. It claims to be 3,000 psi. Right now I'm leaning towards the Loctite, but open to suggestions. I am convinced it must be a 2-part epoxy. I ordered some Titebond III wood glue (not 2-part) which got rave reviews on the Internet. My acid test was to glue two pieces of wood together to see if the wood broke before the bond did. Bond broke, but will use it for occasional wood to wood items. I tried to pry the type of glue originally used out of Herman Miller, the manufacturer, with no luck. By-the-by, they charge something like $1,500- to do what I'm doing. So, PC*7, JBWeld, 2-part Loctite (it includes both wood and metal for its use), or?? Back to the Roll Call.
