I just got caught up on this thread. Wow, 38AC sure nailed it. Bravo on your troubleshooting and persistence, Hugh. So glad it worked out. I hope you can find a small machine shop nearby who can help with your custom key project.
For Christmas I got myself a cheap TIG torch, filled my former nitrogen bottle with argon and taught myself some beginner level scratch start TIG. Added a new tap so I could use just 2 batteries plus the sheet metal resistor of my direct battery DC stick welding TIG likes the lower voltage better. Tried some silicon bronze brazing with it too- easy and quite fun. That's what I'd use to build up the top edges of your keys, I think.
Best Wishes,
Bruce
