Mine's not CNC but rather laser oriented, however, if any of my stuff can be made available from SkerchUp, PDF or CorelDraw (eg SVG, DWG, DXF, ???) for CNCing just ask... wont even cost anyone a cask. Must admit though, I'm G-code ignorant... code RC... code!
If your first cut is too short... Take the second cut from the longer end... LBD
