    I need a knurled nut !

    Tom , it sure is an expensive mic , which is why it deserves radically better maintenance that it has had . The cable exit and strain relief are a serious design flaw . Every one of these mics I've seen has the same problem . The mic is free to rotate on it's 'strirrup' type mount , but the...

    I need a knurled nut !

    Yes indeed , rhankey , the knurled nut 'bites' directly on the thin metal shell . I don't think the shells were threaded . To assemble the mic it's necessary to feed the cable through the shell and the nut , but the nut can only be screwed in once the shell has been fully fitted . Because of...

    I need a knurled nut !

    Luc The 8.45mm includes the 2mm of thread . In the past someone had tried to build up the hole using solder , but used normal tin/lead solder . Doh ! Yes indeed , I'd quite like to be much closer to Ottawa ! That's the problem with this little job , it's proving very difficult to find a local...

    I need a knurled nut !

    I need a knurled nut !

    Luc Here's a few more . It's obvious that the mic internals have been desecrated over the years . Apart from the knurled nut and the horrible mess made of the mounting hole , there is an internal bracket (obscured by gaffer tape) that is fundamentally the wrong shape . The cable clamp needs...

    I need a knurled nut !

    Thanks Cogsy & CanadianHP . I'm in London . There's a little bit more to it , but the knurled nut is the crucial piece . It screws into a thin walled , possibly spun , metal housing . The thread has , over time , gouged the 'meat' from the hole it used to mount in and is now too loose to fit...

    I need a knurled nut !

    Hi I'm trying to find a little assistance with a simple metalworking problem . I have an old and rare Sony microphone which has been abused during it's lifetime and now requires some very simple parts to get it back to health . Specifically I need a small hollow circular 'nut' that serves as a...
