Recently I was contacted by the owner of a bona-fide genuine Mongolian-made fiddle. She has had difficulty keeping it in tune from the beginning and wondered if there was something I could suggest. We discussed options and I came upon a plan to retrofit it with mechanical tuning machines.
The multistranded nature of morin khuur strings necessitates a large diameter peg. Unfortunately the materials used here weren't up to the task. The pegbox seems to be made from a fruitwood, and the pegs themselves *might* be an Asian variety of soft maple.
The wood is just too soft and fibrous. Assuming I had a peg shaver large enough to deal with these, I'm confident they would quickly deform. No amount of peg compound is going to help this situation!
The cheeks of the peg box were too narrow to accommodate the electric bass tuners I had in mind so I made up a couple of little risers.
The shafts fit nicely into the vacant peg holes. I scribed around them...
