Hi All,
I posed a question on the Classics and Cruisers forum about the problems caused by captive nuts that aren't! and thought my eventual solution would be of use to anyone facing the same problem. My problem was specifically the nuts used on the peashooter silencers of Thunderbirds. Read on.
I am now pleased to report that I have found the answer to the problem. As I thought, it is possible to drill a small hole adjacent to the mounting nut through the steel of the silencer and just touching the visible part of the nut, into the nut underneath. Insert a pin of a suitable size. I used a ground down nail. This locks the nut into place, preventing it from spinning and you can then use mole grips to undo the shank of the bolt. Or you can cut a slot into the bolt and use a screwdriver.
I have just done this, this weekend with total success. Once the bolt was out I used Araldite to secure the pin in place and trimmed it down flush with the silencer.
To avoid a recurrence of the problem I have cleaned out the threads of the nuts with a suitable wire brush and bought a new set of brackets which I intend to fit using spring washers.
I don’t see why this solution cannot be made to work with any similar loose captive nut situation.
I hope this helps any one else with an unusable peashooter silencer. If any clarification is required please ask and I will do my best to help.
