Refining the edge and arching

I spent time today cleaning up the edge and the arching. For the cross-arching, I am using curtate-cycloids, which seem to follow Cremonese arching fairly well and are at the very least a practical concept for the arching. I have the edges down to about 4.5 mm, so once the edges are adequate, I can put the purfling in. First, though, I will get the back to near the same state to get the corresponding edges and overhangs somewhat coherent.
