Since I need about 10 sets, I am looking to get some made since these are no longer available. Any interest?  |

I bought a load from Norbo when I first joined.
I think they were stainless steel.
I now just use nylocks or loctite.

I am looking at mild steel then zinc plating them. I tried some stainless disc locking tabs, but they kept snapping off or twisting round when tightening, so not going to use stainless.
Meadspeed also do them, but they are £9.50 a pair plus £3 post.
I will make a test one and see how it fits :-)

Ready to race almost Rob I reckon!
Maybe finger tighten up the 2nd nut and good to thrash.

Adding lightness  (joke for anyone who sees this later...) looks good Rob. |

I wanted to make some in mild steel as I have had issues with some stainless material in the past where it was too soft and too brittle, so snapped easily.

I wanted to make some in mild steel as I have had issues with some stainless material in the past where it was too soft and too brittle, so snapped easily. I agree, stainless is the wrong material for this application. Stainless steel is great for certain applications but not for others. It is less ductile than mild steel, and so is not right for a component that is actually designed to be bent. I don’t get people who use stainless steel screws inside engines. Its main advantage is aesthetic and it does not rust. Neither is relevant inside an engine bathed in oil. But there is the chance of gauling on removal from the aluminium cases, especially when they have been exposed to heat. It should also not be used on heavily loaded areas. It makes me cringe people bolt disks on with fully threaded stainless screws. Let alone the material properties, the fact the stress raiser on the threads is put under load is not a good idea. Jon |

Totally agree Jon, stainless has its applications but I dont like it for many things on bikes.

I have some of Norbo’s stainless hex head and flange bolts for the side cases etc. now these are being used for aesthetic reasons. However I will be spraying the threads with liquid PTFE before fitting to the aluminium cases.

Mi too but will be using molycote 111 on the threads
Use it at work as a peristaltic tube lubricant but excellent for stopping stainless galling
Found when doing up m4 SS bolts with a cordless driver if you went too fast the stainless would generate enough heat to lock them solid

Just got the first batch of 128 from the laser cutters. Need to get them plated next...

Get next set laser cut from zinc plate! Surely the edges would rust? Jon |

I ordered some from Fowlers for the SR125 but they were on back order. I got fed up of waiting for them so made some myself out of 1mm zintec then zinc/nickel plated them myself. Making them by hand was a long fiddly job but as a one-off I don't mind doing it. Zintec is a coating designed to be painted or powder coated. It's not great outdoors on it's own and discolours and rusts easily if it gets wet. Galvanised sheet steel is much better at resisting corrosion but I don't believe lasers can/will cut it. Probably because it spits back and ruins the laser lens. The zinc on a galvanised sheet is supposed to migrate onto any cut edges and kind of 'heal' the bare steel. It's a bit like the sacrificial zinc anodes on a ships hull preventing it from rusting.   |

Nice job, you could have your own little cottage industry Those took hours to make by hand using tin snips, files and a drill. I could charge £20 a pair and still only be making £5 an hour 😁. I have done them on CAD so I could have them laser profiled if I needed any more but the Yamaha ones finally arrived and are in a drawer somewhere. It's handy for any one off parts though. |

Pre-galvanised steel. Can be easily laser cut, my previous company lasered it all the time. Doesn't really rust, seems to seal the dege as it cuts. If you worried you can put a special paint which we used to brush over welds, and sometimes touch up raw edges. Just a thought. Nice work though. |

If you worried you can put a special paint which we used to brush over welds, and sometimes touch up raw edges. Just a thought. Nice work though. I have had a lot of laser profiling done over the years but always by a 3rd party but we now have a laser here. It's run by a sister company who share our building. I was asking the guy in charge of it about it's capabilities regarding type and thickness of metal. Copper would be nice for head gaskets but he said it's not capable of doing copper. He also said galvanised sheet. We do zintec all the time but galvanised steel is dipped rather than electro plated. He might have said the zinc spitting back at the laser lens was the issue but I can't remember exactly. I know different lasers have different capabilities and capacities and some can certainly cut copper but apparently this one doesn't. I was watching it cut one of my jobs yesterday. The speed is impressive. I would have done a video but didn't have my phone on me. |
