The angle on the letter could be built with:
- a chamfered router bit   (would require a fair bit of manual cleanup)
- our smaller bandsaw, tilted table (this would require the chamfered router bit on the inside of the "R")
                                    (or maybe use the jigsaw, tilted table)
- use the shopbot to CNC a slope
- or mayyyybe done by hand, but that's both more work and less precise
