When I'm stack cutting I use CA and kicker. Wood must be flush on all sides. Stand wood on edges up right,flush up edges,squeeze tight and run very small bead of CA then spray with kicker. Hold tight for 4-5 seconds Your done. Do this 2-3 times (depending on length of edge) on each edge. Run bead front to back not full length of edge. Use medium CA not thin. Try to not let CA soak in to much before you spray the kicker.Wood will not shift.
