After more rough arching, I finally squared the edges up for the purfling

these are the tools used on the purfling platform and arching

finally starting to take shape

the arching is not as full on the outer ections as the wood was cut poorly and very thin on one side

using a 5mm allen key to set the outer purfling line

using offcuts to have a test on how this is going to work

the outer purfling line is now marked

now after a tool reset the inner line is marked

the purfling line around the lower bout

using a strip of purfling I marked the line under the button and started cleaning out the groove

by going in stages the groove is lowered bit by bit

I have to say, hand purfling a cello back sucks. After 5 hours I still have to clean more out of the lower bout grooves.
