« Part 5: Violin 2 - The Jig for the ribs Part 6 of Musical Instruments Restoration series Part 7: VIOLIN JIG - The CLAMP for bending »

Here is the progress of the Bandurria picolo continued from this blog.

Nothing much done but this is the most crucial part in the assembly. The ribs both the starboard and port (left and right side) is difficult to clamp and glue. I have to think a lot on how to do it. The photos below will explain it.

As it looks like a mummy wrap around by a garter (1 inch width). How long? I dont know. Aside from the garter, there is also a rubber strips of 1 inch width and 1/8 inch thick. Also place some small pieces of wood strips in the edges where I want to push the ribs in. The ribs and the plates (rear and front) are bending so much and needs to be clamped and wrap around. Two things: 1) If you just clamp it from the front plate to back plate then rib will pop out. 2) If you clamp it to ribs criss crossing then the plates push out. So above way is the best.

Note: Normally, the ribs are the one done first… but in this case, I then finished the two plates first. Actually the plates are new and ribs are old… this makes it difficult to do… that is also the reason why restoration and repairs are difficult to do.

But life must go on… there is no turning back as long as there is no damages that are not beyond repair. I take out the garter and tapes just when the glue had a little bit dry (this is the time when there are no more white glue instead a transparent glue.) I noticed that there are some bulging on one of the ribs. So I reclamp it carefull and manage to put it to the right place. I forgot to take photos because my hands all wet with glue.

After this…. SANDING …. SCRAPING and here it is…

You can see that the ribs are already shorter and I have to square it so that I can glue another strip on it.

Notice how clean it is after several scraping and sanding the neck and the ribs.

And the front…

UP TO HERE at this time…
Next in line will be the interesting fretboard…. facing the following problems:
No dimension of the fret spacing….
The fretboard is not fitting correctly with the front plate… but it fits on the neck…
The frets in brass has to be made… I cannot buy the right stuff in the store…They always offer steel.

Here is the one I need from you…
Can I still make the rosette? My daughter said it will be good if it will have a design on the front! Marquetry is the best… Paul is expert on this… but I have my second thought that if ever I will make it on this… it will be a nice first marquetry but it will be very difficult and I might destroy this bandurria just because of the ambitious thing to do. I should do it on other project but not on this bulging surface and has only 1/8 inch board… As long as there is music to be produced that is okay for me…. Let me have your suggestions.

On the way to go tomorrow for the fretboard…
Till then… Have a nice weekend.

Nice Work Bert!
It sounds like you are uncomfortable with adding the embellishment, or Rosette… Don’t!
It looks perfectly fine now, and as you say, the sweet music that will come from the instrument
will be embellishment enough!
