Re: Neapolitan Mandolin Build in Naples - November 2022
Thank you, Sebastiaan, for this (literally) breath taking account. You are living my dream right now.
You've enlightened me on something in the rib assembly process, that I've discovered (doh!) in 3-D modeling a bowlback rib/ stave construction (and laser cutting cardboard ribs to test fit...which is the furthest I've gotten).
Yes, the 'outside' curve of a rib will need to map a slightly different curvature on the mold than the inside one.
Above, you've described the fitting process of these ribs as such:
"The centre back of the bowl is relatively flat and the bowl then rises steeply. this transition occurs over four ribs each side. These ribs need to be twisted as they are fitted so the procedure is a bit different now. Size and fit the rib to the mould, glue and nail the rib in at the head block, secure the rib with pins and then glue the tail block end. The rib is then covered in glue with particular attention to squeezing the glue into the seams. Paper is then placed over the seam and the hot iron is used to coax the rib into the correct shape. When done properly the ribs end up perfectly aligned as a bend that would be impossible to execute properly off the mould “melts” into place. "
When you have a moment, could you elaborate on this a bit?
Any further description of this process would be fascinating to me.
Thanks!
I look forward to the next phases of your project saga.
Mick
