This is a Keystone 16 size hunting case that Mary Ann Scott sent me to repair. I have took several pictures of the process of removing the old hinge and replacing it. This first picture is of the case.

This picture is of the really deep scrapes in the case frame. To make the hinge replacement look good when done. I decided to fill in the deep scrapes.

this one shows where I added some metal to fill in the deep scrapes on the case frame. In this picture you can see where the old hinge has been removed. Case is ready for the new hinge.

Thanks for your time.

Very nice job Leon!
Is the case solid gold or gold filled?

Leon - the case turned out wonderful! I am so pleased and can't wait to get it back! Big Grin

The transformation is incredible. What was once a beat up broken case now looks like it was just made!

It is gold filled, is original to the movement and has a very nice inscription, so I wanted to restore it. I am glad that I did. I highly recommend Leon and the work that he does! Thank you!

Leon,
That's a beautiful job. Did you grind the old hinge away, or did you use a sep disk, or ??? Those laser welders are nice, that's for sure.
Thanks for showing this project. I'd like to see more of your case work.

Hi Peter, I have 30 years as a jewelery repairman. So yes I did grind the old hinge away, and yes I did use a sepereting disc in a hand piece. I have reworked a Hamilton model 2 case that I need to get the pictures on the 185.

Leon,
I'd love to see the pictures for the Hamilton model 2 case. I used to work on watches, but a few years ago I decided to concentrate on making jewelry (although I still "dabble" in various watch areas), so I like to see this kind of work. I worked part-time as a bench jeweler and I got to assist the jeweler in a similar case repair -- it was a lot of fun to see how it shaped up. Thanks again,
Pete
