Hi there. I have this window mechanism to repair. I was thinking I should remove the whole window and remove the mechanism to fit some sort of new pivot point on this part as the old one has sheared off.
I've never worked on a window like this before and so far I am not sure what kind of part I could source to act as the pivot point/axle that would be suitable and last.
Any ideas?
First thing that comes to mind is to replace it with a button head machine screw. A bit of work with a drill and tap will get you threads at the pivot point (if the original stub was not threaded, it might be) and then you can use a screw into those threads to act as a pivot. A good serve of loctite to hold the screw in place and ideally a nylon washer between moving parts (if clearance allows) and it should hold up well.
Another option which would be a bit more work to do well would be to remove both sections of the mechanism, clear a hole through the pivot point, insert a short length of steel rod, and peen over both ends. The hard part would be spreading the ends well while also maintaining easy movement - judicious use of the hammer would be required.
