Hi banjo folks!

I noticed that my RK R25's 5th string tuner has been becoming harder to turn, and today the plastic knob broke when I was changing strings.

Can the tuner be lubricated? The plastic knob was epoxied together, and is currently in the drying process.

Thanks for your replies~

Sewing machine oil may help it limp along, but it's essentially shot. Sorry.

Personally I would just buy a new 5-Star tuning machine and replace it/have it replaced. They are great and will last for ages.  5-Star tuner. StewMac.com

Good luck! Hope this helps!

It looks like the problem has been solved!

There's a white plastic ring surrounding the post that is supposed to keep out dirt, etc. that is easy to move aside. So, I did that, and squirt some light-weight oil (Hetman's Lubricant #13) inside the tuner. i used a very small open end wrench to turn the post, and it's very easy to turn now.

The glued plastic knob has to wait overnight to dry good.

You can't keep a good banjo down! And, if so, it's good to have a backup banjo...

Thanks for reading.

Thanks for your reply, R. Squirrel!

I'll have a better idea how it works tomorrow, when the plastic knob is put back on. It turns real nice with when i use the open-end wrench, though.

I'll keep your suggested tuner in mind, as well.

Thanks again, and happy pickin'.

Might be best to just install a new tuner. A Gotoh 5th is only $12. I bet the knob will break quickly after reinstallation.

While the tuner pegs on RK's are usually Chinese made and not the same quality as Gotohs or 5 Stars etc, most of them work well. (remember there are a heck of a lot of RK's around the place). If the repaired button holds up, well and good. If not get a replacement button.

Yeah, I'll probably go that route, Bob.  I'm just buying some time with the current "fixed" status.  The glued plastic knob stands a good chance of not holding up for too long.  

Thanks for your advice.

Hi Kerry,

The main problem with using a light lubricant to "free up" tight tuners is that it then migrates slowly back out of the tuner, often soaking into the wood that holds the tuner and eventually seeps under the finish.  You can guess what happens next.

Most epoxies are rather poor at welding most plastics and useless for some plastics. I suspect your tuner button won't hold up very long.
A commercial choice for plastic repair is some form of Methyl Methacrylate, but it may be hard to find in small quantities.
I think the closest thing to it, is Devcon Plastic Welder 2. But in any case, as suggested, buying a new tuner will probably be cheaper than the glue and more satisfactory.

Thanks for all the info and advice. Looks like a new tuner is in order here.

Hey Bob, where are you seeing these Gotoh tuners for $12, now that I'm looking around?  I appreciate your help.

I'll report back tomorrow, as to what happens when I reinstall that glued knob.  Maybe someone will take bets...ha!

He's seeing it on his own site.

Scroll down. You'll see it. Gotoh fifth string tuner in nickel, with your choice of button. $12. Plus very reasonable shipping.

The current Stew-Mac Five-Star fifth string tuner is a Gotoh. Why pay more from them? Get it from Bob.

For one small tuner, the postage in the US is only $5. I don't advertise that on my website, but no one has ever complained about me charging less.

As promised, here is the result of that glued-back-together tuner knob ...it didn't hold up. It was working fine without tightening it down, easy turning, too. Then I tried to screw it down, and it caved.

Bob is sending my a new one, for the lowest price that I found...$17 total! Very fast and efficient ordering over the phone, too.

Thanks for the help... to Bob, and those others that gave their opinion. Happy pickin'!
