Spire Nuts, removal of.
Ferranti U1003,
The wooden panel on to which the loudspeaker is fixed is attached to the main cabinet with several of these rectangular push-on fasteners. Whats the best method of removal without wrecking the cabinet ? regards Ian |

Re: Push on fixings -- removal ?
I use a very fine screwdriver, or a pair of needle nose pliers, and gently ease the small teeth back - the clip then falls off.
To refit you just need to squeeze the teeth back down, and push onto the stud with a nut runner. Cheers Sean

Re: Push on fixings -- removal ?
Sometimes it's possible to thread two lengths of thin strong wire under the lugs. Pulling on the two loops formed will then often allow the 'spire nut' to be pulled off.
Another method is to grip the sides of the nut with pliers and screw it off by turning and pulling. Graham. |

Re: Push on fixings -- removal ?
As Paul says, it's very difficult not to snap the plastic posts. The fact that there are often 2 posts suggests the makers didn't expect anybody to remove these successfully - you can disassemble once, then that's it
When the post breaks the clip will fly through the air and it's easy to lose it. I managed to break *all* the posts securing the speaker in my KB MR10, and had to fabricate new fastenings from long nuts and Araldite. Good luck, Paul |

Re: Push on fixings -- removal ?
Some of the things I have which use those fasteners have a post with two flats on it. You can then give the clips a quarter-turn so the clip then slides off the post.

Re: Push on fixings -- removal ?
I either use iron binding wire from a florist, or push a cheap pair of tweezers under the lugs.

Re: Push on fixings -- removal ?
Thanks all for suggestions.
I tried the pulling with fine wire technique first, result was the easy removal of four out of five fasteners. The last one seems to have been pushed really firmly up to the wooden board and the two little clips have bitten deeply into the post. In the end I snapped the post, but as suggested, there is an adjacent unused post; so all is not lost. ! Again, many thanks for all those very helpful suggestions. regards Ian |
