I’ve made some progress on the back from my Stainer 1679 inspired violin.
The purfling channel was cut using two Ibex style purfling markers/cutter, one for the outer cut and one for the inner. This is the method promoted by Roger Hargrave. I found this particularly useful on the belly.
The channel depth was done using at Pfeil 9/10 gouge for the c-bout and a Pfeil 6/10 for upper and lower bouts, adapted from Davide Sora’s choice for the channel. These had the bevel re-ground to create an even support while cutting.
More on the method soon…
