Look up 3M and Loctite epoxies. They both make a number of very good epoxies each with different qualities. Either are a syringe type setup and you have to purchase a dispenser but they’re not expensive.Saw this (old) thread (nice bass design!) and was curious about this technical point - what brand is the adhesive you mentioned? Is it a two part epoxy? I'm looking for something to bond plastic and bone (for a custom bridge) and wonder if the adhesive you used would work better than super-glue or standard epoxy from the hardware store.
