Well despite having visitors for lunch I managed to finish the 'billet clamp'. Time will tell if it is strong enough but I think gentle cutting is the order of the day. Were I doing it again I'd place the nuts closer together along the length of the bolts. As they are a standard M10 tap isn't long enough to pass through both to clean up the threads - only one was in desperate need and I had to grind back the shank of a bottoming tap for it to pass through nut 1 and clean up nut 2 ! |

That clamping spider is very good. It will surely be useful to you in future as well and easy to add to if you have some horrible irregular part. Allthread coupling nuts might be good to use for this as well. I have some M10 ones that are 13mm A/F so if these are common, that might help where space is short. I think you are OK, but it is worth double checking that if the horizontal clamping bolt or lock nut ends up with its points vertical, it still meets the height restriction. Or use cap screws as the mock up. |

That’s a nice clamp idea. |

I had one M10 coupler in stock and although the local Screwfix had them and was open Bank Holiday Monday we were suffering the annual London to Hastings 1000 motor bike run on the A21 outside the farm gate I didn’t fancy my chances! So I stuck to the double nut solution 😀 |

I would have stopped in but I was meeting someone and too pressed for time. There were a lot of bikes though. |
