nope, rohacell is not like depron, it is hard foam wich remains after pressing it , when i press a small piece between my finger's i can't notice any swelling after release.
the TE of my wing's are paper thin and remain that way , altough the cores had 0.3mm thickness
TE of a kevlar wing i cut with a sharp knife using a cnc'ed wooden template
but for the slot of the aileron i use this tool ,it also is nice to do the cut's on the side of the ailerons , the thickness of the disc is perfect for free movement of them .
