Hi folks, I'm hoping the DIY boffins can help. I'll do my best to explain clearly.
I have a metal pedestal composed of several parts. The frame (Part A) is topped by a male thread. The secondary part of the pedestal (Part B) also has a male thread. There is a threaded coupling (female) designed to join these two together (Part C).
The thread snapped off from Part B. The item that the pedestal is supposed to hold is quite heavy, therefore the whole frame is temporarily useless.
Things I've tried:
a) inserting a supporting rod between the parts (a metal chopstick)
b) duct taping the whole thing
c) a convoluted rigging up of shoelaces (don't ask, I was trying to 'innovate')
As I'm sure you can imagine, none of these were successful. Aesthetic is not a priority here, as once the item is mounted the frame can't be seen, hence my imaginative attempts to fix it.
I am considering buying a soldering iron next, or perhaps taking it to a welder, although being such a small task I don't know if this would be considered unusual.
Not sure what part A, B or C are in the picture or what the final structure needs to be, but a soldering iron will only marginally help, you can solder some parts together with tin but this type of soldering is not strong enough usually
There are stronger glues you may use to bind two metal parts. But if this needs to hold a serious weight welding would be the best. Just ask around any small metal workshop you may find - they should not shy away from any metal work, nomatter how small
Hard to judge by the photo. You might be able to drill and tap the top part, then replace the broken-off piece with a bit of threaded rod (or is it maybe just a broken piece of threaded rod that you could fiddle out of the top piece and then replace?). The threads would have to fit obviously. This only works, if the top part is sturdy enough to receive a thread, though.
Yes, this, our town has an "expensive" hardware store, where it's filled with professional builders, as compared to our Hoornbach and Landi, which is filled with people like me. The expensive place is good for specialty tools and also advice on projects/introductions to folks who know what they are doing when it's something I can't fix.
I also agree that the soldering likely will not work.
Soldering will not work for heavy weights. Welding would work but the time and effort to finish it properly might take it out of the "quick and easy fix as a courtesy" category. There are compounds that can join metal but when required for a heavy load and without knowledge of the underlying metal characteristics, there is risk of the part failing.
The idea of making a new part B seems most reasonable to me. If new threads could be cut to the existing part B (as suggested in a previous post) that seems to be the easiest and most effective solution. If a new piece of metal is required due to a fixed length requirement for Part B, making a new part B would be the next option.
Depending on the dimensions and thread on the part, its possible something "off the shelf" could be purchased and then cut to length. (A hardware store could help you determine this.) If not, a "machine shop" should be able to do it for you. The work is not technically difficult but the tools needed to do it correctly likely put it out of the DIY category. If you have strong desire and envision cutting threads on other parts regularly, it might be possible.
I might look for an independent farm shop or something that has agricultural service capability and see if someone there would just do it for you. In a well configured shop, and unless there is something really odd about your part, shouldn't take more than 5-10 minutes.
We've had a couple of welding jobs done, by the local 'Auto Carroserie' They have all the gear, and will be local. Cost varies from, free to coffee 'trinkGeld' for 5 minute jobs.
You can help, by getting all the bits cleaned, polished or sandpapered ( emery ) and a layout / template drawn ready if necessary.
