Hi Guys, Hope you can help me and the rugby club. Our irrigation system uses 2" gate valves ( 6 off), trouble is that the handles are made of Mazac this disintegrate if left wet (which happens as they are in chambers 2' under the rugby ptches). At ached is a photo of a remaining handle. The square hole is tapered, small is about 7.65mm (Nato std round!!) to 9 mm square. It is stamped "W7" So far the only source I've found is to buy a complete valve for about £60! and just use the handle :doh: I need at least two. Am prepared to pay! Question to you all: How to broach a tapered square hole :bugeye: Stay safe and regards to you all Will, Malahide Rugby Club PS: No one has told ther grass to cocoon itself and stop growing!! |

Maybe something like this would do the job with a bit of adapting. Certainly nothing to lose at the price. https://www.ebay.co.uk/itm/Gate-Valve-Iron-Gate-Valve-Handle-Ball-Valve-Hand-Wheel-Shutoff-for-Water-Pipe/383515658658 |

By one of those brass 3 way key things that have square ends of various sizes. Visit a good plumbers merchants that primarily deals with the trade (i.e not mega store). They should be able to help you out. Failing that, it is quick and easy make a handle out of brass. Get a brass bar. Mill a slot in it (or file it) so it snuggly fits the valve handle. Now you have a square hole, with one side open. Solder another piece of brass to the open side, to form the square. Steve |

Will how good are you with a needle file? Turn a suitable brass disk, bore a tapered round hole on the lathe, file the ‘tapered square ‘ with an all square needle file. Not much material to be removed as you are starting with a tapered hole. |

Why not remove the handle and make a 5' long wrench like the utility companies use for underground valves? |
