A method and apparatus is provided for making impressions of edges and profiling the edges using a profiling machine. The apparatus allows the impressionable material used for forming the impression to be held in a fixed position while the impression of the edge is formed, and then allows the impression to be withdrawn in a manner that leaves the impression substantially unchanged and substantially true to the profile of the edge. The apparatus also comprises fittings to make the apparatus compatible with a profiling machine and allows the impression to be positioned in the profiling machine in substantially the same orientation every time an impression is taken.
