A pattern for a new violin model - a Bergonzi. I make the ply shape to the exact size of the mould form including the corners. Establishing the block
positions and heights is important as this defines the radius of the corners.The ply, with a 6mm spacer then serves as a guide profile
for a following cutter on router. Ply moulds are one thing I don't use my hand tools on - even the good stuff has stones in it.
