There is a term called blue and glue used by CNC people. It as a way of securing small project down for carving. I have been using this for over a year with no slips at all. I put a layer of tape on the sacrificial board and then apply tape on the bottom of the piece I am going t carve and then I apply 5 dots of super glue to the tape on the piece I am carving and then place it on the other tape. Once I am done with the carve I can stick a butter knife between the two pieces and twist it to remove the piece from the CNC. When I remove the tape from both, there is no residue left on either.
