I'm using the German method of fixing the ribs, that we were taught at school - did my exam in Markneukirchen - as opposed to the conventional Cremonese method using an inner form, not because it's better but because I didn't want to spend time making a form for a one-off instrument. In this method the form of the back is finished and then the ribs are bent to fit. The corner blocks are fitted last. It's quite a lot harder to get the same even result as when form is used, but it useful when experimenting with different shaped/sized instruments.
Here is an inner form that I've made for a double bass. It is after a John Lott bass that belongs to the Gothenburg Symphony, which I've had the privilege of having in the workshop.
I've got this far today. Axel told me that he would like a black violin with a heart shaped scroll. Why not? I'd already rough cut the scroll, but was inspired by a heart shaped "cheerio" that we found in Axel's breakfast cereal on Valentine's day to make a hole that you can peep through. It's still just roughly formed now. I'll do a close-up when it's finished.
