tuner fail...
I have these cool late-30s/early-40s open gear tuners that drop
right in as replacements for the Kluson Deluxe that came on my 57 Country western. I installed them and put on all the strings. When I began to bring the strings up to pitch, some of the worm support rivets popped out of the baseplates. I never expected this to happen. I wonder - is there some 1940 mojo that escapes me? My installation included something "clever" I came up with - perhaps I caused this failure? Here's the story: My Country Western has stamped "grommet" bushings. The 1940 tuners have associated cast(?) bushings, the kind with a splined OD that presses into the tuning head. I didn't want to modify my guitar at all to install these tuners, not even to ream the tuning head holes to fit the appropriate bushings. The string posts on these 1940 tuners are non-standard - they're not anything I know about anyhow. The two sizes of grommet bushings on Stewmac are for 1/4 string posts (large) or up to 7/32 string posts (small). The OD of the large bushings is right for my guitar, but the ID is wrong for the 1940 string posts. The OD of the small bushings is wrong for my guitar and the ID is too small for the 1940 string posts. So my "clever" idea was to get a set of large grommet bushings and sleeve them with the right sized pipe. McMaster Carr has every size of precisely sized stainless pipe you can imagine. A dot of cyanoacrylate and the bushing is sleeved. The sleeved bushings fit the tuning head holes perfectly, and the string posts perfectly. The lips on the sleeved bushings are smaller than the originals, leaving these "racoon eyes"... I imagined that since I'd solved the string post fitment problem, that I'd just find some bushings with the right sized lips, sleeve them, and be good-to-go for the next string change. But now that my tuners are flying apart, I guess they're no good, or my sleeve idea doesn't cut the muster, or... ? Did anyone read this far? What do you think? -Mike "I put my old tuners/bushings back, my Country Western is unharmed " Last edited by hubcapsc; 04-20-2021 at 05:43 AM. Reason: transposed ID and OD |

sigh...
Anywho... I have these brand new Kluson Prestige tuners on there, and they work great -Mike "original style Kluson Deluxe still drop right in " |

Too bad that happened. I am not a fan of "Vintage" parts. I like brand new, especially if it drops right in.

This is a common failure on tuners with riveted worm supports. Sometimes they can be repaired by rebradding. The bent worm supports are a bit more resistant to leaning than the flat ones, but they can pop loose from the baseplate, as you have discovered.

someone who can do that kind of work (rebradding = repeening?)... -Mike |

I have in the past refitted the posts back into place and then followed up with medium to hard solder, they are still going strong to the best of my knowledge

Nickel plating wont come off in temps under 800c, I have hard soldered many nickel plated items as I repair saxes and trumpets etc as well
