Troublesome Door Hinge

[WK57ABF]

Hi -If anyone can come up with a simpler fix than this it would be much appreciated.

Problem - the pin on our bottom door hinge keeps working out. I have hammered it back in place a dozen or more times and swaged the alloy casting over the top, but it still keeps working out.

This "stubborn" hinge pin has no intention of ever staying where it's put. So I plan on trying to get the top pin out, take the door off, drill out the two blind holes in bottom of the hinge castings, replace the door using 1/4" SS bolts to both hinges complete with lock washers, nyloc nuts and possibly loctite for good measure!!

Anyone else had a similar problem?

Thanks, John in the UK
