26 forum posts 2 photos | The item was designed and made by me this week. I have no control over the adverts & have refused any monetisation from Youtube. |

530 forum posts 89 photos | Nice job then Greg. Unfortunately these days I, along with many others, tend to be more and more suspicious of items being purported as one thing but actually are something else. So no offence intended. If you design and make other similar items do post details on here as these are just the sort of thing we like to see on the forum. All the best Mike |

Nice fixture, Greg … and well demonstrated too Just one naive question from me: What grinding wheel do you use? MichaelG. I like to use a 46 grit for most things, especially when using the side of the wheel. I find it clogs less & cuts cooler. 46KV. |

Greg Webb 1 | 25/09/2023 08:49:55 |
26 forum posts 2 photos | I machined the profile on a thicker piece of mild steel on a CNC mill. The excess thickness was then removed in two halves on a manual mill using the side of an endmill with the finished face against the fixed jaw. Then it was surface ground to thickness on both sides. |

320 forum posts 1 photos | It was the return part of the "shaft" feature that had me foxed. It looks like quite a reach if you are machining that in steps. Martin |

26 forum posts 2 photos | Sorry Martin I am trying to post an image from underneath that should explain how it works but I can't. Any tips on pasting? |

26 forum posts 2 photos | That was a bit of a faff to sort out, hopefully the new software arrives soon. So you can see the holes underneath for 5 - M4 cap head screws that go through the base & key then into tapped holes in the bar.
The elliptical hole is tapped for a sprung loaded ball grub screw that clicks into the vees on the stop shaft. This allows the stop shaft to rotate without losing its position as demonstrated in the video.
