After spending a wonderful week at the American School of French Marquetry, it’s time to build my own chevalet. How hard can it be? :-P. I purhcased the hardware and full scale plans from Patrick Edwards of ASFM, and also downloaded Shipwrght’s 3D Sketch up model that he generously made availabe on Google’s 3D warehouse.
Why build a 17th century tool that is used for traditional hand cut marquetry with a CNC machine?
1. I have a bunch of plywood to use.
2. I like the irony.
3. I know more about Sketchup and Aspire than I do about using hand tools! Hopefully this will change.
4. Seemed like a good project for the Shopbot
I picture some knitted brows from experienced woodworkers this boggling process, as seen at some of the Vetrics demos where, after a lenghty explanation of a proecess used for a simple cut, an audience member states the obvious- “Why didn’t you just use a router?” So, hopefully you all will at least find this blog entertaining!
To begin, I split up Shipwright’s model (afte making a height adjustment for me) and laid out pieces according to sheet thickness:
I made them all 2D outlines, but unfortunately could not outupt as vectors. My brilliant husband was able to import them into Rhino, then output to Illustrator as vectors, so we could then open in Corel Draw for clean up. Easy, right? :-P
Clean up took a bit of time, welding all of the paths and deleting unecessary nodes. Then I could import to Vetrics Aspire to create tool paths, and nest the shapes together. Here is the 3/4” sheet:
Will probably use the drag tool with a pen in the machine first to triple check measurements! More later…
