Plexus (methyl methyl acrylate), 5200 (polyurethane), epoxy
are all good adhesives for this application.
A good clean bonding surface is important, so sanding
with 100 grit paper followed by a wipe with a non-residue leaving (not paint
thinner/mineral spirits) solvent/cleaner such as acetone, lacquer thinner or denatured alcohol is best practice.
The wood chosen for blocks is important, non-oily domestic hardwoods such as birch, maple, locust, hickory. etc. would be first choice. Blocks of non-oily tropical hardwoods are even better, but somewhat dearer and hard to find, though the prevalence of their use in flooring
has made them easier for an effective scrounger to find... careful though, because some of them are so hard that they almost have to be tapped to get screws into them.
