very very cool!! looks great i would love to hear it. Reminds me of a Zeppelin or old airplane. I've been thinking alot lately about alternative resonators for sitar and tanpuras as I have a few nice faces kicking around but the trial and error process does seem daunting. Balsa seems like a good fit as you can build in some tension but it seems like it would not be too bright or heavy like maple or mahogany. Lots of work building that frame I am sure

wow,many thanks for posting the Lahore maker's Youtube. It's very clear they use some kind of pine for construction. I've had several Sher Md sitars that I really loved and they were apparently pine....without stripping them it was difficult to conclusively determine this. I was fine-fitting some pegs and noticed the smell was just like pine when cut.
building a tumba out of ribs like a lute makes perfect sense. A gourd is a wonderful natural 'ready made' sound box but the fragility and spongey inside texture doesn't necessarily add any advantages. Pine type woods are readily available and easy to work with. Pine being a softwood, some of its qualities would approximate a gourd moreso than hardwoods.This Youtube has saved me a trip to Lahore and endless questions.... sometimes I can only say 'thankgawd' for the Internet.My next sitar build is now going to be pine with no hesitation!

Glad it was of some use to you Coyootie. They use some kind of glue sawdust and ground dust paste on the outside and then sand it down smooth. Wood strips I was told are soaked in water first. I was very surprised how light it was in weight.

the major challenge in making a rib-built shape is laying out the templates for the ribs. I've made rough models for ouds out of elongated leaf-shapes cut out of shirt board and then taped together to make the form.I'd do something similar to establish the shape for a nice sitar tumba. Once you have it figured out, you're good to go.I've found if the wood is flexible enough it's better to bend with dry heat only and not to soak the ribs.
