Corner braces
Waterjet cut parts can also be used in brackets that are aligned so that the cut edge, rather than the face, connects to the part. This is accomplished using the t-nut technique. The low cost of waterjet cutting allows you to make corner braces at custom angles and with mounting points in the positions you choose. Since the cut edge is in contact with other parts, you might consider low-taper cutting for this application.
