Door lock removal question

[fireguyfire]

I need to remove the cylinder door lock on my 1940 half ton, and have been trying to figure out a way to remove the partially stripped and rusted in set screw that you need to remove through the hole in the door edge to be able to remove the lock cylinder out of the outside of the door.

I’ve been hitting the screw with PB blaster and hit it with some heat before trying to remove it today, but have had zero luck . (Also, interestingly the is no cylinder lock on the drivers side of my truck).

can anyone make any other suggestions on how to get this set screw out, or am I stuck with having to try and drill it out through that same hole in the door edge.

In this time period, was typical when you went to town. You would park at the sidewalk then slide out the passenger side door, instead of opening drivers door into the traffic lane.

I won't say that everyone exited the car this way, I imagine it was geared towards larger cities where it was more important to practice this procedure.

The larger populated cities would have a larger automobile market to cater to.

Those out in the country or small towns never bothered to lock the doors.

 

For the same reasons they moved the floor shifter up to the column, they called this a improvement because it was easier to slide across the seat to exit.

From the window opening, a long drift and snapped off the keeper screw and it's "home" with a hammer and the lock slides right out.

I used a small drill to drill down the center of the set screw. I then went in with a larger and so on, until I was just hitting the threads. Then run a tap. In my case I damaged the threaded tube the set screw goes into. I used a structural two part epoxy to add a new tube, with threads, after drilling the original most of the way through. I had to manufacture the new tube using a lathe and a piece of SST rod.

It has worked great, but if you can get a drill down the center and then use a small extractor, that would be a lot easier.
