I have used double sided tape without tear-out. Only problem with too much tape has been denting the surface with a chisel trying to break the joint.

Another technique is to put the pivot pin on the bottom of the surface - works well for tables.

Final technique is to make a full size template from 3mm MDF and trim with router with bearing.
