I have been restoring an old cabinet and I had to replace the handle, now I have a new glass handle with a brass collar but I need to weld it to the screw thread which the door catch attaches too.
It’s an extremely small job, it only involves welding an outer circle of brass to an inner circle about 10cm in circumference, so I’m not sure where to find a welding service for such a thing, or indeed just someday who can weld.
