Anders Nielsen Posted November 16, 2020 Share Posted November 16, 2020 Nice, exactly what i was looking for. Now vi just need some measurements of the wiring "clip" And the screw, is it a screw or a bolt? It is listet in the parts list whit the same part No as the screw for the chain guard.. So the must be Identical. 1 Quote Link to comment Share on other sites More sharing options...

flyingfleasteve Posted November 17, 2020 Author Share Posted November 17, 2020 Hi Anders. I will take some detailed measurements and post them on this thread when I have them. The clip is fixed with a screw, not a bolt.👍 1 Quote Link to comment Share on other sites More sharing options...

Ron Posted November 17, 2020 Share Posted November 17, 2020 I don't think you could use a 1/4" bolt on that clip. Far too big. I've used a 2BA (nut on the outside) Originally it was probably a 3/16" BSC which is near enough the same as 2BA. Ron Quote Link to comment Share on other sites More sharing options...
welbike Posted November 17, 2020 Share Posted November 17, 2020 Yes, now that I have the Norton clip in my hand, there's only a small rivet holding it together. Thanks, Lex Quote Link to comment Share on other sites More sharing options...

flyingfleasteve Posted November 17, 2020 Author Share Posted November 17, 2020 Hi Gents. So I have now had a brief look at the dimensions, my digital calipers have stopped working but I have tried to be as accurate as possible. I normally deal in MM but I have tried to convert to Imperial 🙈 Screw thread length = 26/64” The part is flared:- The largest exterior diameter = 15/16” The inner part of the exterior flare = 7/8” Inner diameter = 3/4” Width = 1/2” Screw hole = 13/64” 1 Quote Link to comment Share on other sites More sharing options...

That great.. Just to be sure, I also need the thicknes of the material? And then we can have a batch of them made . Quote Link to comment Share on other sites More sharing options...
Anders Nielsen Posted November 18, 2020 Share Posted November 18, 2020 (edited) First attempt ... Approved or ?? I also make the screw and nut, but if they can be bought cheaper then I do it instead.

The front rod is 5/32" with a 3BA thread. ((4mm rod might do?) But this guy is good with BA stuff / taps&dies and might be able to help with suitable rod. https://www.ba-bolts.co.uk/ Ron Ron, am just measuring this now, and I find my original is not BA, but 5/32" x 32 tpi. So a Model Engineer thread, can someone confirm? as we're having some repro's made. 5/32" X 32 TPI ME (tracytools.com) Cheers, Lex Quote Link to comment Share on other sites More sharing options...
Ron Posted November 22, 2020 Share Posted November 22, 2020 You're probably right Lex. I think I tested mine by using 3BA screws and nuts as a gauge. I certainly wouldn't have anything 5/32". I'll take another look tomorrow to see the fit of 3BA. Ron 1 Quote Link to comment Share on other sites More sharing options...
welbike Posted November 23, 2020 Share Posted November 23, 2020 Just measured the other side, the end of the rod is also 5/32" x 32 where it screws into the part where the cable ferrule screws into, and that is 2BA, just checked it with a tap, and thread counting device. Getting somewhere! Lex Quote Link to comment Share on other sites More sharing options...
Ron Posted November 28, 2020 Share Posted November 28, 2020 I've just double checked both the male and female threads on my brake rod with a 3BA screw and nut and both spin on freely. My rod was on the bike when I bought it but as it was missing the top adjuster, it's very probably a repro from Metal Magic. There is less than half a thou between 3BA and 5/32" and the tpi is very slightly different, so I guess the two won't screw together without force.

welbike Posted November 28, 2020 Share Posted November 28, 2020 Ok, thanks Ron, maybe someone else can measure his rod?? (pun intended!) Cheers, Lex Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted December 20, 2021 Author Share Posted December 20, 2021 Since completing this restoration I have spend most days looking for the correct decompression lever and air maze filter. The bike is so orginal I felt these last few details would finish of a nice project. With an airmaze filter purchased some months ago I finally found the decompression lever (well most of one) A Christmas miracle! 1 Quote Link to comment Share on other sites More sharing options...
