If someone produces a table of bird feeder threads and other useful standards like watering can rose tapers, outside tap connector threads (there are at least three) and pea netting mesh sizes, we could produce a pull out for MEW. Is pull out a suitable phrase when talking about threads? |

754 forum posts 2 photos | Sam, Looking at Ed's images, the feeder looks (to me anyway) to be die-cast rather than plastic. |

863 forum posts 104 photos | Just to confirm, it is die-cast. I found a 1/2" 'pipe' tap at work today. Will check when I get home. |

Considering the many possibilities Neil, it would be some pull-out. It was meant as a joke But it is mind-blowing how many threads and fittings there are that are standard for obscure purposes. Pen nibs, windscreen wiper fittingss, cotton real bore sizes, clock key squares, guitar string ends, aerosol nozzles, sealant nozzle threads... Neil |

![]() 922 forum posts 332 photos | I need to eat humble pie for making a momentous mistake. The green component in these two photographs had, to me at least, every appearance of being a polypropylene injection moulding. As Ed has indicated, it’s actually a metal die-casting. I stand corrected. Neil, your tongue-in-cheek humour didn’t go unnoticed, especially when you included pea netting mesh. Clearly, your humour does draw attention to the vast array of non-standard threads. There’s many a true word spoken in jest. For those still not bored with my interjections, here’s ‘Your starter of ten’...
"Specify this thread!" It's fitted to the end of a domestic broom/brush handle. Cheers, Sam |

"Specify this thread!" It's fitted to the end of a domestic broom/brush handle. This page (https://softsolder.com/2013/04/01/broom-handle-screw-thread-replacement-plug/) from "The Smell of Molten Projects in the Morning" has some details on plastic broom handle threads - potentially biased towards the US but nonetheless, enough to be going on. Ed's daily blog is well worth going through as well as an aside.

1025 forum posts 204 photos | In the plastics industry, there are many threads that are non standard, as they make the tooling nominal sizes, and the shrinkage alters it. They also make the tooling with a guess of the calculated shrinkage , and will then tune/change the one that is either easiest to either change the diameter, or to make another with compensated pitch. Glade that you have solved this one. Often I have made a cast of the thread, then measured it. just plaster of Paris works fairly good too. Neil |

![]() 441 forum posts 29 photos | Thinking laterally;
1). Use a heat gun to soften the blue plastic coarse thread on that pole, then screw it into the die casting, (assuming the OD and ID are close enough). 2). Coat a suitable release agent onto the threads in the die casting, then insert a rod of smaller OD to the thread ID, and fill the gap with epoxy and hold the rod still until the epoxy has set hard. 3). If you don't need to ever disassemble it; don't use any release agent but just epoxy a suitable pole into the thread 'socket' 3a). Glue a short metal rod with a known thread on the outside end into the die casting, e.g an M12 bolt with the head cut off. Then drill and cut that known thread into the top of the pole you want to mount it on. |

![]() 922 forum posts 332 photos | Mr Lickfold, Neil, how dare you mention shrinkage? Actually, I found it a breath of fresh air when you touched on (mould) shrinkage, with its many ramifications. Upon reflection, it feels as if I spent a large chunk of my working life dealing with the subject, often against the flow of a few controversial 'recommendations'. As for potting (either in plaster or epoxy), I ran a bit roughshod over Raphael Golez’ Macro-photography thread with this interjection … Particularly potting in epoxy resin.to determine how two (M&F) threads aligned. I could prattle on but won't. Cheers! (Loud ones) Sam |
