Broken Classical Guitar (already!)

Hi Olly,    Usually when the tuner goes tight under full tension it is usually due to wear in the brass worm gear, this causes it to slip between the teeth on the tuner, then they try to pass each other as they are out of sync, this causes the tightness, you can buy the buttons singly but I would advise a complete new set of tuners, not that expensive for classical guitars. 

Thanks a lot

I'll look to getting a new set and hopefully this will be the end of the problem!

Unfortunately nothing is ever simple...

I got my new tuners but they wouldn't quite fit fully into the head.

It looks like they are slightly longer than the others.

So I thought I would swap the new ones with the old but they are slightly different.

So now I am going to have to mix and match parts to get it to fit - ie new tuners with the worm drive, using the old plate and gear and whatever the part is called the string wraps around!

Can you not take them back and exchange for the correct ones? although I've always thought they were quite standard sizes, you could always take the correct size wood drill, and insert into the peg hole and give it a couple of turns by hand, (not in a drill) this should give you the extra depth you need, 

and the screw holes on the plate don't make any difference as the old ones will covered anyway,
