I acquired these last week. Anyone know what they are? They are only about 20mm long, and the long face is precision ground. Could they be edge stops when working with sheet metal? Frankly, I haven't a clue! John  WP_20180701_16_35_02_Pro[1] by inkaboat, on Flickr |

Miscellaneous Acquisition Disability. I've got the same problem. I suspect we're in good company on this forum.

Look up M & W "Key Seat Clamps" Thanks for that Jason. £32.00 a pop just to turn your ruler into a marking out gauge! Amazing that people will pay that much for something that could be milled out in a few minutes. John |

Back in the day they probably did not have a mill to make a pair and after marking out their keyway would have cut it with a chisel  |

Much to my surprise, it ran OK. The Americans would have just called up a new truck...  John |

So how are "Key Seat Clamps" actually used. Yes, it'll be obvious once explained - but at the moment ........

You put them on a ruler, then it will lie along a bar. You can scribe the bar, perhaps to mark the position of a keyway.  KeySeatClamp by Wilf, on Flickr Wilf |
