110 forum posts | I think you will find that the round stays of the average umbrella are 8BA size exactly - if you can find one on the local scrap dump. 2.5mm MS welding rod is the correct size for 7BA studs which are widely used on the smaller Stuart Steam Engines. |

Mugging little old ladies to measure their umbrellas with a micrometer seems a bit extreme. I am sure a hunt through the cupboard of SWMBO will turn up something ! Kind Regards David |

A tool in the form of a button die, but without the thread, an external reamer. I think there was mention of a tool similar to this, with a taper, for making the tapered plug in a plug cock in Model Engineer a good few years back. Ian S C |
