Here is a worn tarav mogara. The string is deeply ingrained into the bone rim… this needs to be repaired.
Start with removing the bad piece with a tight-fitting metal pin. Pry it out gently by turning round and round with the metal pin. Clean up the hole…
Select a new one, make sure it is well-fitting!! Or, if you are lucky and it didn’t break, then it can be re-used by rotating it over p.ex. 90°, or 180°…. Glue it, and let it dry.
Apply shaping with a hand-made mill.
Clean it up, check the hole (it may be obstructed by dried up glue) and mount a new string…
Metal pins, hand drill & hand-made mills.
Kartar Chand & Hari Chand add a special tiny tarav mogara bridge to support the string.
Hiren Roy & Barun Roy and many others install a differently shaped mogara.
but which glue should i use for gluing the mogras
Best glue for almost everything on a sitar is ordinary wood glue. The simple white stuff that you can find everywhere…!!
