Stripped external door hinge, no problem.......

Post by bwaminispeed »

My buddy had a set of MKI/II door hinges, in pretty decent shape, re-pinned a couple, and, all the threaded holes were okay except one.........

Well, after checking through my stash of finicky repair stuff, I found I was out of 1/4-28 helicoils.........what to do, what to do......

Always more than one way to skin a cat, how about a two different sized stud, should work ok, no????

Turns out it works fine, here's some pics....

Not only could I not find any 1/4" Helicoils, I also couldn't find my 1/4-28 Die.........Oh well, I do have a screw cutting lathe, gotta do it the hard way............

Finished part......the split nut was so I could hold it in the Lathe Chuck, without damaging the threads.......

Stripped hole was just big enough to take the 5/16 UNF tap.......Only had a bottoming tap which wouldn't start in the hole, had to cheat........used a 5/16" UNC taper tap to just get a couple of threads started, then the UNF bottoming tap went right in easy peasy.......Sometimes ya just gotta do what ya gotta do.........

Once tapped, the two threaded stud spun right in.......

Fixed, Oh joy..........

Then, after doing all that work, I just realized that that particular hole uses a screw, not a stud........ :lol: :lol: :lol: :oops: :oops: :oops: :cry: :cry: :cry:

Looks like I'll have to go get some Helicoils after all :roll: :roll: :roll:

Nonetheless, it’s a nice idea and very fine work. Now to find a stripped hole to use that nice stud😁😁

Well, as it happens, I found one (stripped hole), just barely 3 inches forward of the first one I did........ :| :| :|

Just had to shorten the big end of the double thread stud, dito repeato the tapping procedure, and, William is your Mum's brother.....

Great work there, on my original 850, on the third thread starting from the side that goes on the A panel, a pan head screw is used as otherwise it damages the rubber door seal , I think.

What is the general opinion ?
