Hello There, I have been searching all over the net for information on how to fix my tuning button. I bought my Collings MT new in December 2007 and just this weekend while away for some R&R and jamming, the inner G string tuning button just began to spin when I attempted to adjust the string's pitch. ARGH!

Looks like the tuners on my Collings MT are Gotohs & have screws at the end of each of the pegs. I removed the screw from the tuning button & removed the “spinning” button from the shaft. When I took the button off I discovered that the “collar” of the button is part of an inner plastic piece that fits over the "two flats round shaft".

When the button has become disengaged from that inner plastic piece (as the one on my mandolin has) I can easily see the fit between the inner piece and button is not a smooth fit or one that has flats to create a firmer hold. It looks to me like a bit of space is present between the inner plastic piece covering the metal shaft & the button itself. I wonder if there is a reason it’s designed like that?

Is there a particular type or brand of epoxy I should use to glue the button onto the plastic sleeve that covers the metal shaft? Should I be concerned with “filling in” the gaps that appear between the inner plastic shaft cover & button in order to maximize the contact between the two pieces?

I'm quite upset this has happened as I've been so kind to the Collings & we are at such an early stage in our relationship! Any advice on how to deal with getting the MT back up to a fully tuned 8 stringed instrument is SO very much appreciated!

First off, welcome to the Forum. Sorry your first post had to be about a problem, no matter how small it might be.

First thing I would do is call your dealer, and then Collings. If you bought the mando new they should cover a new tuner button for you.

In the meantime I would try to clean the button and the little "bushing" and put a drop of super glue on it till the new one got to you. Just don't get the glue on the the shaft of the tuner, keep in in the button. That should hold it for you.

Greetings Rick and thank you for your welcome & reply! I followed your advice and contacted my dealer (who is in another city) and he is now sending me a replacement tuning button via the post. I can't wait to get back to playing my MT once again!
