I apologize if this is not where I can post my question for help. Please let me know where it should be posted.
I picked up a Hughes Dulcimer (1981) second hand. It's an hourglass model with geared tuners and one tuner is stuck. I sprayed a little WD40 in the gear but it didn't help. I believe the tuner part that goes into the hole thru the wood is where the problem lies; after years of non-use and not being taken care of properly, the wood 'contracted' around the tuner such that it's stuck.
What can I do to free the tuner so it works?
In the event I need to replace the tuners,
