The brand of epoxy does not matter so long as you get the slowest curing type you can find. I use extended cure which gives me a half hour of set up and takes 12 hours to fully sure. It has a holding strength of 3,500 psi and will be stronger than the wood you use for the scale.
Make sure to rough up both surfaces to be joined and clean with a de-greasing solvent like acetone.
Here is a sneak peak at the display base. I will use some grainy Bubinga and some sort of deer antler.
