Need to replace worn return springs, and the idea to create them seems simple - find some sort of threaded insert that will grab and hold onto the inside of the spring. But does anyone know the actual threaded insert part that is inside the return spring that a screw can anchor into? a name? or link?
Seemed like it would be some sort of a standard threaded insert as you see for wood with teeth on the outside to grab, but wanted to check to see if anyone knows. I don't want to tear into one of my current ones before I can figure out how to put new ones together! Thanks |

and they don't slip or move around once inside? How do you get them in? |

| I believe the spring itself narrows down to accept the screw threads. I don't believe that there is an insert of any kind with-in the spring. Personally I'd prefer not to have this adjustment feature. |

Return springs need to be adjustable. If you prefer the method of nibbling at them with pliers, fine. I prefer screws.
I assume the threads have the right pitch to fit the inside of the narrowed portion, although I haven't gone into it in detail.

Welllll...yes and no. Thousands of pedal steels have been produced with non-adjustable springs, and most are still being played. While it can be a handy feature sometimes, I wouldn't exactly call it a necessary one.
The more things you put in a device that allow "adjustment", the more likely that sooner or later an improper adjustment will be made. (Donny's first law of mechanics) |

I just open a little gap in the spring and shove the nut in.

| PSGP sells a set of springs, screws, Anchor plate with attachment screws, May be something to consider, May make a good upgrade. May be just be for old MSA spring spacing width. |

Indeed. I'm not suggesting that just anyone should be let loose on things they can fiddle with
