Thanks in advance for any advice.

Revolver is a model 1917, Brazilian contract. Hammer post is broken off.

Gun is a shooter, but is a favorite of young owner and I am attempting to help with repairs or finding out how to repair.

Any suggestions?

Fred

Are you referring to the Hammer Stud?
27-3 Accessories | Numrich Gun Parts

gunpartscorp sells them for $2.75.

The part is press fit into the frame and I have no idea how to remove the broken one.

Probable buy one for an N frame and have a good gunsmith remove the old one and press in the new one

the model 1917 hammer stud (thanks for correct nomenclature) seems to be installed from outside of frame. There is a head of the hammer stud visible below cylinder release "thumb piece". This seems to be the norm for this vintage revolver.

When I get back home I will try to post pictures.

Thanks,

Fred

Replacing a hammer stud isn't a job for an amateur. It is difficult to accomplish without the proper tools. You are correct that the stud is pressed in from the outside of the frame. A jig is used to brace the frame while the new stud is pressed into place. The jig prevents the frame from warping during the process. I would not trust this job to a "smith" with a hammer and punch.

The hammer stud at this time period is not pressed into the frame, it is screwed in! You may need to make a spanner to loosen the broken stud, or simply use a punch against the notches in the stud flange to break it loose. Unscrew the broken stud, screw the new one in, with red or green Loc-Tite if you wish, and you are done. Not hard at all!

I have never had to deal with a broken stud, but sure have had to tighten a bunch that were loose over the years. Exactly the same process.

Link to M 1917 hammer stud on Numrich: Hammer Stud Gun Parts | 358200B | Numrich Gun Parts This takes you right to the specific item. They are $2.75 each. With my experience with Numrich I would suggest buying 2 or 3 just in case, you might get a good one! The annoyance and cost of multiple orders, wasted time, and shipping costs if the first one is NFG is well worth the extra money the first time!

Yup, these old ones used threaded studs. Whenever I had to tighten one, I would also stake it in place with a center punch. You then have to stone it a mite, as it leaves a burr.
