Pistol Pete Posted September 23, 2015 Share Posted September 23, 2015 My WSCC Keyring fell apart tonight, the springy bit is held in by a long screw from the bottom. Might be worth undoing and threadlocking it or just tightening it up at the least. Quote Link to comment Share on other sites More sharing options...
Quinten Posted September 23, 2015 Share Posted September 23, 2015 <true Westfield spirit> Can you not upgrade it with a better screw? 3 Quote Link to comment Share on other sites More sharing options...

Rab (bombero) Reid Posted September 24, 2015 Share Posted September 24, 2015 I torqued mine down as per the manual .. seems fine! 1 Quote Link to comment Share on other sites More sharing options...

Man On The Clapham Omnibus Posted September 24, 2015 Share Posted September 24, 2015 You can get carbon fibre screws. Jen That page about screws took me back to 1967. I worked as a project engineer for GKN at their newly formed plastics development centre in the old PECO Machinery Works on the riverbank in Chiswick. The boss of the centre was a Herbert J Sharp PhD, a metallurgist, and I was one of a staff of three engineers looking at projects that would fit in with GKN Group's repertoire of products and that would provide a basis for the Group's ambitions to grow in the plastics industry. Bert Sharp had been close to a university bod who was developing the newly 'invented' carbon fibres and he (Sharp) though that as GKN's history was in fasteners, CF bolts were a good start. Instinctively I though it a bad idea and that panels and other parts with smoother profiles would be more suitable but as a junior plastics engineer I kept my views to myself. It is fascinating that it has taken fifty years to realise this idea into a physical product. Our attempts at making CF reinforced bolts were rather less than successful, needless to say. If Bert were still alive I have no doubt he would be gratified to see that his idea was practical. Quote Link to comment Share on other sites More sharing options...
Onliest Smeg David Posted September 24, 2015 Share Posted September 24, 2015 My first 2 WSCC Key rings failed within a short time! I was hoping this new style one would be better Quote Link to comment Share on other sites More sharing options...

If Bert were still alive I have no doubt he would be gratified to see that his idea was practical. Indeed. The clever bit of these ones seems to be how they have aligned the fibres along the helix of the threads, making them more resistant to stripping. At the same time the fibres are along the axis of the bolt in the centre giving good tensile stiffness and strength. All done with a clever mould filling process. Six plus Euros each though!

Man On The Clapham Omnibus Posted September 24, 2015 Share Posted September 24, 2015 In my lab in autumn, before the works heating system came on, I used a fan heater to take the chill off. After we started working on carbon fibres a new phenomenon developed. Every now and then there would be a bl**** great bang and a flash inside the fan heater as it ingested yet another wisp of CF from the air and shorted across the fan elements. The fibre momentarily passed an unimaginable current then blew apart with a sharp crack! Shook me the first few times it happened I can tell you!
