So I couldn't help myself so I went to the workshop last night and got started 😁
I clamped the neck to the body and found it has a nice tight neck pocket, and then went ahead and found the scale length and centre line down the the body.
FIRST MISTAKE 😆
I didn't have a pencil so I drew my markings using a pen and now I can't erase my mistakes, tried sandpaper and that didn't really work either , my mistakes will stare me in the face until I add paint 😅
