Plane restoration problem

[snafuspyramid]

I'm cleaning up a Stanley 289 at the moment. It was in really terrible shape when I found it, but is cleaning up well.

I've removed the rust with citric acid and the remains of the paint with stripper.

The lever cap screw (that tapped into the plane body) was a bit stuck with rust but came out without any Herculean efforts after a soak in WD40.

Now I can't get it back in. The thread on the screw seems clear enough, but I can't see the thread in the hole. I can see the bottom of the hole however so I know that it is not obstructed by, for example, a bit of Japan.

It threads in about 1/3 of the way but no further.

Does anyone have a suggestion to fix this issue?

Sorry turns out this will be a non-thread. The answer is one that my father would have been happy with (more WD40 and more brute force). All better.

If WD40 and brute force can't fix something, it can't be fixed

Not so, you forgot duct tape.

So I could have just given up on the screw and duct taped the iron onto the body. Maybe that will be the next big thing in plane tuning.
