Thanks much!
For the cad design of this cross, I just used an old version of AutoCAD LT... something called QuickCAD. I found a design I liked, and converted it into .dxf format. I am converting everything over to RhinoCAD 3-D slowly but surely.
For years I've had that design. In my pre-CNC days, I'd make the lines dark and photocopy a printout of the *.dxf file. Then, I'd put a clothes iron on the highest setting and proceed to transfer the design to the piece of wood I was carving. Then, I'd take tiny chisels and cut out each square and try to keep the depth consistent. Once that was done, I'd get the fun of making the knot-work weave over and under. Nowadays, the CNC does the part I hated... I've still got the fun part, and I've got my cross in a tenth of the time. Thanks much!
