Stripped Cadet tumbler help?

[Jack C., 69th NY]

Upon cleaning the lock of a recently obtained smoothbore 1851 Cadet I discovered that the hammer screw was held in place with loctite or some other material. The tumbler is stripped clean, not even a sign of threads. Otherwise, the tumbler notches are in great shape. Can it be tapped for a larger hammer screw that will still appear correct for a Cadet musket? I just hate to throw it into a parts box, never to see the light of day again.
Thanks for any input or ideas.

A lot depends on the amount of metal present. I have used a larger screw or bolt and then turned the head done to the proper size. The shank can also be turned down and then threaded.

Words of advice. Be very careful on your thread size. I you thin the walls of the tumbler to much the hammer blow will break the tumbler shank off. Good luck my friend.

I would drill and tap it to the next larger size, install a grade 2 bolt with Loctite, finish it flat and then redrill and tap to the correct size.
Not sure but I think I heard the original threads are sufficiently different that you could have a hard time matching them.

I would see about replacing the entire lock with the reproduction that is being used in the repro 1851 Cadets. As I recall, the internal parts are from L&R and easily replaced if needed. I would really hate to have to replace any original 1851 Cadet lock parts, beginning with the main spring!

Give a call, I would like to give it a look. I do have some Cadet parts.
