Changing tuners on a Warren May dulcimer.
Instruments- discuss specific features, luthiers, instrument problems & questions
The Grover Sta-Tites that you are looking at are mechanical friction pegs just like your wood tuning pegs. I did not check the dimensions of the pegs, but you would need to make sure your holes are small enough to accept the new turners. Frankly those pegs would not be a great improvement over Warren's tuning pegs. I had one break last year. I sent Warren the peg. He repaired it and send it back to me along with a new peg at no cost to me. That's great service. I put the new peg in and it works fine. If you were to use Pegheds you would have to make sure you the size of the holes in order to get the correct size tuners.
